8/13/2009 Joculator Pygmy Angel Nipping At LPS Corals, Please
Don't Say "I Told You So!" 2/27/09 Hi
Bob, <Hello Laura, James with you today.> First and foremost,
your crew and website are, bar none, the greatest educational tool I
have encountered in this hobby. <Thank you.> Now for my dilemma,
which won't surprise you in the least. One month ago, I purchased a
C. Joculator Pygmy Angel for our 85 gallon reef. <Wowsie, are you
sure it is a Joculator? Very rare, are only collected from Cocos and
Christmas Islands and command a very high price, upwards of $800.00. Is
also known as the Cocos Pygmy Angel.> She is beautiful, healthy,
eats like crazy, and is virtually the little queen of the tank,
basically running the show in there. Her downside? She is nipping at my
open brain coral (which I purchased at 4" and has grown to over
8" within a year), and a beautiful multicolor Blastomussa. <No
guarantee on pygmy angels being reef safe.> Ironically, I have a
Crocea Clam she ignores, as she does most all other LPS and SPS corals
in the tank. These are the only two corals that take offense at her
occasional, but consistent pecks. She is good most of the morning,
after she eats her Spectrum pellet breakfast, but by noon she is
starting to pick at the two LPS I mentioned. I truly don't think
she is after the corals themselves, but more the slime or detritus she
can find on them. I read your site and got a lot of tips on keeping
these little guys away from the corals. She is a juvenile, and I have
had her one month, so her habits are not set in stone. I started to
drop in a few Hikari algae wafers, hoping to keep her busy and full.
These she loves, and they definitely keep her occupied for a couple of
hours, but by late afternoon, as soon as the wafers are gone, she is
back to the two corals in question. There is no doubt that when she is
kept occupied with another food/picking source she leaves the brain and
Blasto alone. If I keep her busy enough with other things to nibble,
the two corals return to normal within a day and show no signs of long
term damage. I can't keep babysitting this way (we are going on
vacation for a week in March), and I know these corals will eventually
begin to suffer from the pecking. <I am sure.> I feed Spectrum
pellets twice a day, sheets of Nori clipped onto the glass (she is not
big on these, at least not yet), and give the tank a whole concoction
of phytoplankton and zooplankton daily for the SPS and LPS, corals and
clam I have. We have a 125 lbs of live rock in the tank that she
constantly grazes on. I don't know what other tips or tricks you
can offer me, but any would be appreciated. If it comes down to a
choice between the Joculator and removing two corals, I will choose to
remove the corals, <Definitely.> but I am hoping there might be
something more I can do to curb this undesirable behavior. I am also
fearful that if I do begin to remove corals she is nipping, she will
move on to others she has left alone up till now. If you could suggest
other corals that are lower risk, please do so. <I'd remove the
two corals in question and see if she tries something else on the menu.
In good faith, I can not recommend any corals that would be safe, is
the personality/eating habits of the fish. The Joculator Angelfish is a
good choice/risk for a reef tank with caution, as in all pygmy
angels.> I know Pygmy angels are a gamble in a reef tank, but the
Joculator seemed like a good calculated risk. <It was.> I have
had pygmy angels before, and have been extremely lucky in this regard.
Any advice is more than welcome, and thank you in advance!!! <As I
mentioned above, remove the two corals and see what happens. You are
doing the right thing in keeping the angel well fed to minimize picking
at the corals, but.....James (Salty Dog)> Laura Garmizo
Territory Issue'¦Tang vs. Angel -- 06/27/08 Bob, <<Hi Brian'¦Eric here today>> I recently added a Half Black Angel to my FOWLR tank. <<Centropyge vroliki? Neat fish>> The Yellow Tang that has been in that tank seems to be giving him a hard time and keeping him from coming out of hiding. Every time he comes out, the Tang tries to swipe him. <<Not uncommon, Zebrasoma flavescens can be a nasty character. Especially once well established, and more so if in smallish volumes (sub 100g systems)>> How should I handle this so the 2 can co-exist in the same tank? <<Mmm, the tang likely senses/recognizes the angel as a competitor for algal foodstuffs'¦but I think there's a good chance this will resolve itself/things will calm down soon>> Should I separate or let them figure it out on their own (which I've seen work before), or is this just a pair that will never get along? <<The latter is always a possibility'¦but I think the odds are these two will learn to cohabitate>> Any suggestions would be appreciated. <<If the aggression lingers or worsens, removing the tang to another tank for a few days would likely help'¦or maybe just try rearranging the tank decor first, to create some disruption/distraction/disorientation for the established fishes>> Best regards,-Brian <<Cheers, EricR>> One Too Many? (Adding a Dwarf Angel) -- 05/12/08 Hi Crew, <<Hey, Chris>> We enjoy reading your posts. <<Me too!>> I have a 72 gal bow front FOWLR. Currently the tank is stocked with the following fish: 2 tank-raised Clown Fish (False Percula) 1 Tomato Clown 1 Half blue Damsel 1 Royal Gramma 1 Skunk Shrimp Button Polyps on live rock Nothing has been added to this tank in over two years, and currently I have a Lawnmower Blenny in a QT which will be added. <<Okay>> My question is I also wanted a Coral Beauty for this tank? I read on your post the cubic-inch for 5 gals, I am afraid we might be pushing it with the blenny. I need an expert's advice if the Beauty should be added or not. Thanks in advance! Chris <<This could work'¦ The Dwarf Angel should be pugnacious enough to fit-in with the others 'the trouble will be in finding a specimen of this species in good condition. This Centropyge species generally suffers badly during capture/handling and thus often does not fare well for long in captivity. But if you can find one that is eating and has been adjusted to captivity for a bit, they 'can be' quite hardy and long-lived. I know you already have several red/orange fishes 'but a better and hardier Dwarf Angel species would be my personal fave C. loricula (The Flame Angel). This species handles the stresses of capture/shipping better, and acclimates readily in my experience to captive keeping. Regards, EricR>> Adding multiple pygmy angels 3/28/08 Hello, <Hi> I was at my LFS last night and was admiring a dwarf angel. I advised the salesmen that I already had a Flame Angel in my tank and as such couldn't add another. The salesmen went on to advise me that if I added another 2, (not 1), and then shut off the lights that the angels would get confused and after a couple of hours give up on any potential fight. <Maybe temporarily, but most likely the aggression would return.> Any truth to this or is it just a sales pitch? <Maybe he has had fish with non-typical behavior before, but most likely a pitch.> I wouldn't mind adding another dwarf but everything I have read indicates that you can only keep 1 per tank. P.S. I have a mixed reef tank, 85 gallons with the following fish: Regal Tang, Sailfin Tang, Flame Angel, Blue Reef Chromis & 2 false clowns. thanks, Frank <I definitely would not add another angel to this tank.> <Chris> Pygmy angels, comp./sys. 03/19/2008 Hi, <<Hello Marianne, Andrew today>> I'm learning just by searching your site. I checked out the questions on dwarf angels, but didn't get a definite on this. I was told I can have multiple dwarf angels if I introduce them at the same time. I'm thinking (and was told by the shop owner) I could add a flame angel, dusty, and coral beauty if I add at one time. <<I have seen these together in the same system before. Your tank is a good size. All 3 are territorial, so ensure plenty of hiding places / cover is available. Do add them at the same time.?? The flame is about 2 1/4 inches and the other two are closer to 3 inches. I have a 115 G live rock tank (135 lb rock) with a powder brown tang, sailfin, foxface, and 2 fairy wrasses, blennies (1 scooter, 1 lawnmower), 2 starfish, and 2 diamond gobies. Also have a few Zoanthids, 2 anemones, 2 clowns, and 2 small blue green Chromis (original fish from set up--they lived through it all). The angels would be my last addition. Reading your site, I am wondering if I have too many, but I would really like at least 1 or 2 angels (I should say, my husband wants all 3!). What do you think? <<In my opinion, at best, add one. You are very borderline on your stocking levels. Read more here including linked articles and FAQ's http://www.wetwebmedia.com/marine/fishes/angels/centropyge/index.htm>> My husband takes care of the tank. I don't know the numbers, but he said all is where it should be. Filter-wise, we have "mud filter" with protein skimmer ( sits underneath main tank), and extra pump for water circulation, and 10K (2 white, 2 blue) lights, and blue moon lights for night. Marianne <<hope this helps, A Nixon>> Fine Spotted Fairy Wrasse Lemon Aid? (Dealing with Lemonpeel Angel Aggression) 03/19/2008 Good morning- <Hi there! Scott F. in today!> C. punctatus I believe is the correct name. <No, it's SCOTT F> Heheh, just kidding...Think your reference to a wrasse got cut off?> I have a 55 and the current inhabitants are 1 Lemon Peel, 1 False Perc, 1 Firefish goby and 2 Yellow tail Damsels. The Lemon Peel rules the tank and probably chased the smaller Perc to his carpet surfing death. <That sounds about right, given the typical personality of this species.> I would like to add another Perc and at the same time add a flame hawk and 1 or 2 C. punctatus. Can I add 2 to my 55 if they are not a pair but just 2 individuals or do I need to find a pair or just add a single? <I would limit my fish additions in this aquarium. Maybe the "replacement" Perc and the Hawkfish. The Hawkfish, may be able to better stand up to the nastiness of the Lemonpeel than the Wrasses. Really, adding any new fish to a relatively modest sized aquarium with a known "alpha fish" is a dice roll. Be prepared for possible issues and the need to rescue someone if things get out of hand. You could try the old trick of shuffling the rockwork around to create "new" territories for everyone, but this still may not work. Be forewarned!> I would like to have 2 fairy wrasses so the male will display and stay more comfortable. I want to add them all to the main tank at the same time to spread out the aggression from the Lemon Peel. I would Qt the new arrivals for a month. I would put the LP in the fuge for a week or so until the new fish have been in the main tank and settled down. Thanks again! Walt <Well, Walt, the idea of the "timeout" for the Lemonpeel is a good one! I'm still a bit hesitant to give you the thumbs up for the two Fairy Wrasses. I think that one more fish is really all the system could handle from a bioload perspective, as well as a social one. I can't imagine the Lemonpeel getting any more sociable, but he will ultimately accept (or kill) the other fishes in "his" aquarium. Sounds rather brutal, but this is the reality of stocking dynamics. Proceed with caution! Regards, Scott F.>
2 Dwarf Angels In A 135g Reef? -- 01/29/08 Hello, <<Hi there!>> Just wanted to get your opinion on the likelihood of 2 dwarf angels *eibli* and *loricula *getting along in a 135 gallon (72 x 18 x 24) reef tank. <<Is a possibility. I have kept multiple Centropyge species in about this volume of water with success in the past. Do make sure to have adequate rock/hiding places for these fishes 'and keep all well fed>> If you think this is a decently "good" idea which should I add first (both at same time)? <<I would add them at the same time>> Also, I have a *loricula* in a 55 gallon reef right now, I was considering adding a purple tang. Will the 55 gallon be too tight for the 2 of them (there are no other fish; the 135 won't be ready for approximately a year)? What are the chances the angel will accept the tang if I introduce a tang of similar size (maybe bigger?)?? <<The 55g tank is really too small for either of these fishes alone, and certainly if combined. I suggest you hold off on the Tang addition until the 135 is ready>> Thank you. <<Happy to share. EricR>> Re: New Tank Setup and Trigger Selection... Now Centropyge comp., incl. argi 12/29/07 Hi Dr. Fenner, <Ummm, just Bob please. I have no doctorate> Thanks for the info. Your response about the Cherub concerns me. What is your opinion of adding the Cherub to the new 215g tank with a 2.5" Coral Beauty (at the same time)? <This dwarf dwarf Centropyge should be fine in this size setting> I've searched your site but couldn't find this exact match. I've even thought about putting the Cherub in my 65 gallon sump. I really appreciate all the support your team provides online. Thanks in advance, Nancy <Welcome! BobF> "Sweet" angel, Centropyge comp. 11/22/07 I'm interested in starting a large marine setup and have been researching fish. I'm absolutely in love with the dwarf/pygmy angels. What I would love is an entire tank of dwarf angels... <... not how they live, w/ the exception of harems... of the same species> ok, I'm dreaming. My question is... 1) are there ANY dwarf/pygmy angels that are NOT considered aggressive? <All is relative here...> 2) How many "aggressive" dwarf/pygmy angels could you acclimate at the same time, as juveniles, hoping that some harem? Thanks for all you guys do... I live in a city without a lot of good marine advice sources and your help is invaluable!! Happy Thanksgiving! <Thanks... Please read here: http://wetwebmedia.com/fishindex3.htm The first tray, under the heading: Centropyge BobF> Centropyge Eating Coral ...You've Got To Move It, Move It! 11/22/2007 To the WWM Crew <Hello Flavio, Mich with you today.> I just finished, one month ago, the process of joining two 450 l tanks sharing the same 120 l sump. One of the tanks is about 7 years old /established, so I simple add more 450 l of natural salt water, new and very fine sand and "dry" rock and connected all the system. The new animals are a yellow and a veliferum tangs, a loriculus, a bispinosus and a flavissima Centropyge, two tank raised Ocellaris and a Gramma loreto. Also there I put a Trachyphyllia, a hammer (Euphyllia) and a small Sarcophyton. All the fishes and coral are in good condition. The only problem is that the Trachyphyllia is being eaten by the Lemon peel. At this moment about 10% of its tissue is damaged. Removing the coral to the other tank is a good thing to do <Absolutely!> or is the coral lost considering the amount of the injury and the coral species? <If removed from the antagonist the Trachyphyllia will likely recover. I would not give up hope on this coral.> The coral is lying from the first day on the sand bottom and today is not fully expanded. <Likely because of the continued presence of the Lemon Peel.> Thanks is advance for your advice and for your fantastic website. <On behalf of Bob and the crew you're welcome! Mich> Flavio Multiple Angelfish. Crowding Centropyge 11/6/07 Hi WWM crew, <Pete> I have a 65 gal. that has been running for about 5 months. I have a Red Coris Wrasse, <Will need larger quarters> a Six-line Wrasse, and a Coral Beauty angel, along with some corals. <... some... corals... What species?> My question is at the coral store I go to ( I live in Okinawa ) the tank with angelfish in it had at least three Flames, three Bi-color, and a Half-Black in it and was only 25-30 gal. <Yes... temporary... jammed together...> They all seemed to be fine swimming around in groups, not displaying the behavior I have come to expect from reading countless forums. Any idea how he gets the fish to live peacefully? <They don't... Think of being crowded in a locker room with a bunch of other fellows... tenuous...> I would ask him myself but his English is about as good as my Japanese. Thanks, Pete <Centropyge, other Pomacanthids, other groups of fishes can be housed in such settings for a short while... There is no room for dominance, hierarchy to become established... but it's not healthy, nor sustainable. Bob Fenner> Mixing Centropyge in a Very Large System 8-27-07 I recently put in a 20 foot long X 8 foot wide X 6 foot tall aquarium (roughly 5,000 gallons). I have a LFS shop that is strictly marine aquariums. I went there this past Saturday to see what they had. They have numerous species of Centropyge (nox, aurantia, potteri, flavissima, ferrugata, eibli, loricula, multispinis, and a few others). I have 6 large piles of coral and various rock structures with lots of nooks and crannies. I want to keep at least 4 nox and 4 aurantia angels in this setup. All of the fish are around 1 1/2 inches to 2 inches. Will they cohabitate in this setup. Your help will be greatly appreciated. <Well as I'm sure you know the mixing of Centropyge angels is usually best avoided in the average system...of course your system isn't average if we factor in size alone. With a tank of this volume your chances are definitely increased though the risk is still there, just much more miniscule than usual. I would say that the territory should be big enough to compensate this animals though I would attempt simultaneous, or close to simultaneous addition of course after proper quarantine. Good luck.> David <Adam J.> Centropyge Reef Compatible 4/19/07 Hi, <Hey, Joe!> I am in the process of creating my 36 gallon tank reef, when I upgrade my lighting to a 150 watt VHO fixture (24 inches) and shortly after adding a refugium. At the moment I have a Flame Angelfish and a Clown goby. I was told a while ago that my tank was not large enough for my angel, and could not keep him for the long run. <True. They need more space, are very active.> Also, since I am adding corals, I don't want him to gobble them up, since in the beginning I might know if he is interested or not, since each individual fish is different. <Also true, but unless you are planning a larger tank in the future, he would be better off in a new home.> I truly do like the fish, <They are one of my favorites also.> and don't know where else to give him to other than my LFS, who won't give me anything back for him. <Nothing? Mine will give me half price for a healthy fish, especially one purchased from him. They should be willing to pay wholesale prices for a local fish that has essentially been quarantined and will not have all the stress of recent capture, acclimation, and shipping of a new import. Hmm. This is a common situation, but I admit it confuses me. The LFS should be willing to work with you on making room for your future purchases (he could sell the same fish multiple times at 100% markup if he played his cards right). Sorry, I'll get off my soapbox now. Maybe try again to reason with him, make sure you are talking to the decision maker.> I am not sure of any Local reef clubs either, since this would be a better option. <There should be a way to get in contact with others aquarists in your area who would be interested. ReefCentral has a huge number of local reef club forums: http://www.reefcentral.com/forums/forumdisplay.php?s=d527912f59f1d2456a10f8d690f9d360&forumid=80 > Is there a dwarf angel that is more reef compatible and smaller, so it can thrive in my size tank? <Yes. The dwarf dwarf angels might be what you need. I like the Centropyge argi (Cherub Angel). Much smaller, blue with a yellow face, lots of personality! There are others that are very similar but not as common at my LFS such as C. aurantonotus and C. acanthops. See FAQ's and linked articles here: http://www.wetwebmedia.com/dwfangsysfaqs.htm > Thanks again, Joe <Welcome, Alex> Flame Angel w/pygmy angel? Mixing Centropyge - 4/6/07 I have an established flame angel in a 75gl FOWLR tank. This fish is appx 3 1/2 inches long. <A nig for this species...with an attitude to match?> I would love to add a pygmy angel. <I wouldn't do that with the pre-existing angel, especially of one with such size with "meat on his bones".> Any chance I could do this? <There are always chances but this not time not in your/our favor my friend.> I have read that two angels are not ideal (putting it mildly). <Especially those of such similar lineage...same genus.> However, I have also read that with plenty of hiding spots, it may work. <Yes but if one were to chance this I would only recommend it in tank of at least double this size...territorial/psychological crowding issues of concern.> What are your thoughts? <Would enjoy the healthy Centropyge you have now.> Thanks. <Anytime.> Steve <AJ.> Crazy Flame Angel 3/16/2007 Hello All, <Hello James, Brandon here.> I have a 46 gallon bow front aquarium with 60+ pounds of live rock that I have had set up for a little over 6 months now. I have several soft corals along with the following fish: 1 Flame Angel, 1 Royal Gramma, and 2 False Percs. I just re-introduced all 4 fish after being fallow in my aquarium for 6 weeks due to and ich breakout. <Good idea to let the tank run fallow.> After the re-introduction my nitrates went up to 10, ammonia 0, nitrites 0, Ph8.4, but have been slowly coming back down (I realize this is due to bacteria die-off from having no fish for 6 weeks and then adding a little too much bio-load back). <This is a possibility. Nothing to be greatly alarmed about.> My question is, my flame angel has gotten strangely aggressive. <C. loriculus is one of the more aggressive Centropyge Angels.> He will tip on his side and circle tightly below the clowns forcing them to the top of the water he then proceeds to attack them. <He is defending territory.> If the clowns attempt to move anywhere near the rock work he does the same thing again. I do not see any signs of sickness in any of them, they are all eating like pigs, and they have been doing this for 2 weeks now. What can I do to help curve this aggressive behavior? <You little fish is all grown up, and sometimes they do this when they mature. There are several ways to go about this. First way, move all of the rock work around. This will break up established territories. Second way, Take the C. loriculus and put it back in QT for about two weeks. This will give the other fish time to establish territories. The hope being when you add the C. loriculus back, it will find somewhere else to reside in your tank. Third way, catch the C. loriculus, and start over with a new one. Had I been you in this situation, I would have reintroduced the fish separately, adding the C. loriculus last, as this is the most territorial fish that you have.> Will this behavior ever stop or should I remove the flame angel and get another? <The behavior could stop, or it could not. Removing the fish is one option.> Would moving the rocks a little help (hard to move them too much with all the coral)? <This could work as well, but it would have to be a drastic movement of rock work. As in a whole new structure.> I read your site all the time and find it to be a valuable resource any advice would be greatly appreciated. Thank you, <You are welcome, and thank you for the kind words, Brandon.> ~Jim Mixing Dwarf Angel with Larger Angels. 2/28/07 Hi Crew, <Hi James, Mich here.> Great website, you guys rock. <Thanks!> My question revolves around a pygmy angel that I have in 125gallon fish and live rock tank. I wanted to add another angel (Koran, French or Emperor) down the road. I know you can't mix angels of the same family, but can I get away with this or does Mr. Pygmy have to go back to LFS. <Probably not the best idea to mix these two.> Other fish include small hippo, medium yellow tang, 2 purple fire goby's and a royal Gramma. Thanks, James <Welcome! -Mich> Multicolor vs. Flameback for peaceful, reef safe angel 02/17/07 Hi Bob and/or Crew members, <Art> I gave up on Centropyge angelfish when I turned my 55 gallon tank into a reef tank-- but now I am dying to try one in a reef setting. I have been reading everything I can find, and have narrowed my choices down to a couple of fishes. I know the African Flameback is supposed to be one of the most reliably reef safe Centropyge species, <Yes... a fab dwarf-dwarf> but my dilemma is that I have an extremely passive tank of extremely small, and in some cases rare and extremely expensive fish, and I am concerned that the Flameback angel is too aggressive for them (because of it is so similar to the Cherub). The other fishes in my tank are a 2" Diadem Anthias, a 2" Purple Firefish, a 1.75" Green Mandarin, a 1" Yellow Assessor, and a 1" Candy Basslet that cost the equivalent of a house payment. <Am still amazed at how folks capture this genus... I've barely seen them in the wild... always in the back area of caves...> As far as corals are concerned, I have about two dozen that constitute a Centropyge buffet: Goniopora, Open Brain (I think) Pineapple Brain, Maze Brain, an Unidentified Brain, Turbinaria, Star Polyps, Zoanthids, Purple Fungia, Branching Hammers, Candy Cane/Trumpets, Mushrooms, and Hairy Mushrooms, Torch (or Tooth) plus one whose name I can't remember. <A bunch of garden variety for such a small volume...> Alternatively I am considering a Multicolor Angel, mainly because I like it, also but because it is more shy and reclusive and because of this I am hoping that it is more compatible with the fishes, if not the corals. <Is gorgeous as well... and might fit... I do wish your system were larger though> Actually, I haven't been able to find much information regarding the temperament of this fish. What do you think of this fish with my current livestock? <Temperamentally likely okay... just needs more room psychologically than you have> He will be the last fish I add, and I am planning to obtain a small specimen, about 1.25" body length (this applies to either angelfish I select). What I've read about the Multicolor's suitability for a reef tank is not encouraging, but I thought I would test it in quarantine by adding an LPS coral after the fish has been eating to see if he starts noshing on it. Probably not a reliable test, but definitely easier than extracting him from my reef tank. Do you have any more input on experiences with this fish in a reef tank? <Have seen this species in many reef settings...> Whichever angelfish I select, I plan to feed 2-3 times a day, with frozen brine, Cyclop-eeze, Mysis (if he is large enough to eat it), Nori dried seaweed and also incorporate a Continuous Hatch 'n Feed Brine shrimp feeder in the reef tank, <Neat devices> so live brine shrimp will be continually released into the tank. Basically, offer enough food and enough variety to out compete the coral as a food source. So which one should it be? Any suggestions for success in this endeavor? (besides Genicanthus-- collected too large, and in my experience with a Bellus female, more active and chased smaller fishes). <Also a useful genus... the Swallowtail Angels... for large/r reef settings> Thanks again, as always, Art <Actually... if you had to have a Centropyge, all you have room for is one of the small/er species... I would give a pass to all though myself... and start putting the money away for another (larger if possible) system... I can foresee problems with allelopathy... and your wanting to expand and separate some of your stated animals, fragment some of them perhaps... specialize. Bob Fenner> A variety of Centropyge questions, and NMA fishes volumes 12/21/06 Hi Crew! <Hi Ed! Mich here.> Love the site I learn so much each time I come. <Glad to hear you both like and learn. It is always good to expand one's passions and intellect.> In an earlier post, Bob said that a 150 gallon tank with lots of live rock could handle a Coral Beauty and a Flame Angel. <Yes> I have a 90 with a good amount of live rock (100 pounds or so) I was wondering if this is big enough to host the same? <It might be. Lots of variable come into play none the least include the temperament of the individual fish.> It currently has 2 clowns a royal Gramma some shrimp and serpent stars with oodles of snails. <Well, your system could certain support the added bioload.> An article on your site suggested adding 2 angels simultaneously to reduce territoriality issues. <Yes this would be smart in my opinion. But if it can't be done I would introduce the Coral Beauty (Centropyge bispinosa) before the Flame Angel (Centropyge loricula)> My problem is that my quarantine is only 29 g and to add them at the same time I would want to purchase/quarantine at the same time. If I stagger them, who should I get first? <Centropyge bispinosa tend to be less aggressive than Flames.> Will they do okay in the 29 for a month with lots of PVC to hide in? <They may, they may not. The good news is if they fair well, they obviously should be fine in your 90 gallon, If they don't there are mesh type tank dividers that you could install temporarily to keep them separated while in QT.> I can raid my 'fug for pods and have a dedicated 10g algae tank for fresh red and green macro. Will that help? <Wouldn't hurt!> Lastly, any idea when the "fish book" announced in your reef invertebrate book will come out? <Sorry, I have not hear any rumblings.> <<Mmm, JasonC (if HE finds the time) and I may generate the other volumes... Antoine has seemingly lost all interest... is onto other full-time projects. RMF>> Thanks <Welcome! -Mich> Ed Mixing Pygmy Angels - 10/15/06 Hello crew, <Hello.> Your website is invaluable. <Glad you think so.> I have a question regarding pygmy angels and stocking levels. I currently have a 50 gallon "show" tank (30"x18"x24). The only current resident is a 2-2 1/2" coral beauty. I would like to add a flame angel and possibly a hardy wrasse species. I have read accounts where aquarists have had success mixing these species. Do you think this is a "good" idea in a tank this size? <No.> If not is there another species of pygmy angel that may be "more" compatible? <Not really in a tank of this size - they will likely fight to the death.> I haven't been able to narrow my list of wrasse species to an appropriate selection. I really liked the leopard wrasse but read in multiple sources that this species is very difficult to keep in the long run. <Very, very difficult.> Can you recommend a species of wrasse that might be suitable and interesting? <How about the fairy wrasses?> As far as aquascaping there is around 25-30lbs of live rock in the tank and I will be adding another 20-25lbs over the course of the next month. <The more the better, but still won't change the amount of total space you have.> This is my first attempt at a marine environment. I have been keeping brackish tanks for a few years now and am trying something new (and thoroughly enjoying it). If you have any feedback or ideas, I am more than open to suggestions. <Would just keep your eyes open to possibilities... many other fish out there for you to choose from. Cheers, J -- > <Aqua-C> Skimmer rave and Angel Question - 09/14/06 Hi Crew: I just wanted to take a minute to thank you for recommending the Aqua-C Remora. I replaced my Prizm with one and had some trouble getting it to work. I emailed Aqua-C and the quickly responded to me that my fake decor could be the problem. They recommended I remove it and rinse it all 3-4 times for an hour at a time. Needless to say my skimmer is working like a charm now. They mentioned that fake coral is notorious for causing issues with the skimmer due to the oils that leech into the water. <Yes... a problem that a couple of friends in the manufacture of this are earnestly endeavoring to fix> For anyone that is considering purchasing an Aqua-C please do! They have amazing service and the difference is unbelievable in the skimmate that they collect. Now for my question, sorry to go on for so long. My local fish store is very good and separates all of the Angel fish that they have. <A wise move> I noticed that the only exception to this is that they always keep Flame Angels and Lemon Peel Angels in the same tank. I questioned them and they said that they are the only ones that are compatible together. Have you ever tried this mix? Would you recommend it? Thanks for everything, <Mmmm, by and large, no... have seen this and other combinations of Centropyge together... with and w/o success/compatibility. I would not give carte blanche to this combo. Bob Fenner> Bi-color angel vs. flame angel - 09/01/06 Hello Crew, <Hey, Mike G with you today.> Thank you so much for your help in the past. You are truly an asset to the aquarium community. I have spent many hours reading your comments and learning a whole bunch. I ran into a bad situation with a 5 inch bicolor angel. He fit into the community tank wonderfully for a couple of months and then started to pick on the 5 inch dwarf lionfish to no end. The active lionfish responded by hiding to the corner of the tank and looking sad. <Angels have been known to be aggressive, but I have yet to hear of one that actually bullied a lion. Sounds like you've got a particularly nasty fellow.> Although I love them all, I must say that the dwarf lion is like a puppy to me. To calm down the situation, the only thing I can think of was to take the bicolor angel to my LFS that belongs to a national pet retail chain before I go on vacation in order to put him in a kind of fish jail. <Eek! This is what we call "foreshadowing"> Although the store's policy and their overall setup are less then ideal, I get to know the caretaker of the fish department over time. Even though I don't really trust the store, I came to know that he is a true fish lover. When I return from vacation to pick up my bi-color angel from the LFS, I was told that an inexperienced associate have mistakenly sold my fish as a very large Damsel though a series of errors. I was also told that there is not a possibility for them to get it back from whomever they have sold it to. Needless to say, I was very disappointed, but I do appreciate their honesty. <Ouch! I would be disappointed, as well.> At the same time, I realized that he was actually doing me a favor by holding it for me against their policy. I was promised that a replacement will be ordered, only that they won't know for sure when they'll have it in stock. Although the bicolor angel is not a rare fish, it is hard to find one that would live by eating like a pig as the one I�ve lost. Meanwhile, I have purchased a flame angle to fills the empty space. I really needed a red fish in the tank. After about a month, the replacement finally arrived at the store. The only thing is that it is about the size of an average retail damsel in contrast to the large angel that I used to have. He told me that they�ll try to get another one that matches in size to the one I've lost if I am welling to wait. Here is my question: I now have a 3 inch flame angel in the tank. Would a small bicolor fits or rather a larger one would have a better chance in this case? <I'm going to have to say neither. Unless your aquarium is exceptional and your flame angel a pacifist, I wouldn't chance it. Dwarf Angels are notoriously combative with one another, and I don't see any good coming out of such a mix, most especially when one (the flame angel) has a clear advantage in his size. As far as your store credit goes, see if you can put it towards some equipment you need, additives you're running low on, or more compatible livestock. This way, everyone wins.> Thank you for all your help. <You're welcome. Good luck! Mike G> -Hoshing Bi-polar angels 8/18/06 Hello crew, I have an interesting story to share with you, and a question to boot! I have a 90 gallon tank which is home to a 3 inch one eyed eibli angel who is an extremely territorial fish. <Some Centropyge individuals can be so...> He even spikes my finger when i feed them. I was keen to place my 3 inch blue ring angel in the same tank <Not a big enough volume...> but after reading several FAQs i thought it would be a bad idea. <Agreed> Anyway i decided to give them a try knowing that i would probably have to remove one or the other shortly after. On the first night they were together old one eye was like an angel straight from hell-relentlessly attacking the poor blue ring all around the tank. That night i tried unsuccessfully to remove one of them, so i turned out all the lights and covered the tank with towels to completely black it out until i had time to have another attempt at catching one. The idea was that if they couldn't see anything, they couldn't kill each other (and I'm certain that if this behaviour had gone on, the blue ring would not have lasted 2 days). So when i removed the towels and turned the lights back on the next day, the 2 angels were reasonably peaceful toward each other! <Interesting> As a few days have passed now, they have become even more peaceful. They have come within 2cm of each other and hardly noticed! It's amazing; and a nice feeling to be so lucky that these 2 angels can live together. Even feeding time is without incident. So my question is: is this unusual behaviour? why would these fish suddenly become friendly? Thanks! <Perhaps they became "friends through common adversity". Don't know... but a "hint", "bit of advice" I'll pass on to others to try with similar situations. Bob Fenner> Half moon Centropyge behaving badly ! Incomp. mix period 6/17/06 Hi Bob, Eric or Crew - Thanks for the info. on "lace rock". I now will ask what to do if your half moon angel is going after your clown grouper? <Likely separate them> go figure. My tank is a 135 gallon 72x18.5x25.5 and I have tons of hiding spaces and room for theses guys to swim. The angel is about 4" and the grouper is about 5-6". The angel seems to nip at him a lot and he seems slightly stressed by it. None of my other fish are harassed by the angel. The other fish are sixline grouper, clown trigger <!?> and 2 damsels. Any help? I don't want to get rid of the angel, but will if I have to. I had the grouper first, so he would stay. Thanks - daN <... Likely the Trigger will become an issue... all of a sudden... as well. The Sixline is a Grammistes? You don't want to upset this species even in this seemingly large volume of water... See WWM re the "Systems", Compatibility of all these species. Bob Fenner> Re: Half moon Centropyge behaving badly ! Still not reading... 6/17/06 Thanks Bob, I had a feeling I would need to separate them. Yes, the sixline is the Soapfish. <I hope you are reading re...> I guess I will be removing the angel since all was well until he arrived. I am disappointed as he is a very beautiful fish. Also, it seems a lot of people tell me the clown trigger will "become" a problem. So far..... for a trigger, he is well behaved. <Your time will come...> For a trigger. What do you mean by "all of a sudden" he will become a problem? Again, thanks in advance - daN <Please read... on WWM re... don't write. BobF> C. argi addition - 5/17/2006 Hi there, <Hi.> I have a 50G reef tank containing two A. percula and two G. okinawae. I would like to add one more fish and I have been thinking about a C. argi. <Good choice.> Have I room?, <I believe so.> would there be compatibility problems? <No way to know for sure with individual personalities but likely yes.> and would it leave my inverts alone. <Most do...but no guarantees.> Inverts are Sarcophyton, Sinularia, polyps, xenia and maybe some other soft corals, with hopefully a clam in the future. <The Xeniids and Tridacnid would probably be the most likely prey if the angel decides to "nip."> Thanks, once again, for your time, <Mmm-hmm.. David <Adam J.> Mimic Tang/Pygmy Angel Compatibility -
05/13/06 Hi guys - <<Very astute gals here as well>>
Love your website and how informative it is. Quick question:
I have a Golden Pygmy Angel (have had for over a year), and am thinking
about getting a Yellow Mimic Tang, and am wondering, if since the tang
mimics another species of pygmy angel, I will have problems with
aggression between the two of them? <<Hmm, I have kept different
pygmy angel species together in years past. Several factors
to consider here 'size of the system, size differential
between the fish (if any), and of course, individual personalities of
the fish themselves. If these are favorable then yes,
there's is a good chance the two will learn to get along>>
Thanks advance. Best, Alex <<Regards, EricR>> Lionfish help ... Centropyge comp. - 3/1/2006 Hello Bob <Wayne> I read until my eyes dried out trying to find the answer to my Lionfish question. <Google on WWM, the cached view...> So forgive me if I'm asking a repeat question. I have a 120 Gal, that I upgraded to from a 55gal, with about 50-60# of live rock, Volitans Lionfish, Snowflake eel, Coral Beauty, 2 Yellowtail Damsels. I also have 2 Condy Anemones, Devils Hand Leather, Cauliflower Leather. I'm using a Berlin Skimmer, Orbit 4x96w 10K/Actinic lighting (switched from a Coralife 4x65), a 40 gal refugium with a mag18 pump. I have a small powerhead that I use to keep circulation going behind the rocks. So far I've only tested for Nitrates, Nitrites, Ammonia, and PH, which are a 0,0,0,8.2 respectively. <All sounds good thus far> I just added the Berlin (5days ago), and was using a Skilter prior. <Heeee! Some difference now!> I've had this tank running now for about 7 weeks (upgraded from a 55gal which I had for 1 year). We've had the Lionfish now for about 7 months. Here's my question/concern.. My Lionfish has recently (past 2 weeks, since we introduced the Coral Beauty) started to be extremely active. This is just the opposite of what I'm used to. <Yes... Centropyges can "pick" at Pteroines mercilessly...> He usually hangs out in some "caves" I made for him, and was relatively inactive during the day. Ever since I got the Coral Beauty, the lionfish no longer goes to the bottom half of the tank and is constantly facing the glass and swimming against the current. He is eating well (I feed him a combination of frozen shrimp, scallops, and flounder every other day), and his black stripes are now slightly brown. I noticed one of his eyes looks slightly "cloudy". <Good observation> It's so subtle that I'm questioning whether or not I'm just being paranoid. Paranoid or not, he is definitely more active than I've ever seen him. Today, I restructured the "seascape" and made more caves hoping that he'll get back to normal. Should I be concerned about this energetic behavior from my Lionfish, or am I being paranoid. He has never been this active before. Thanks again for all your help! Wayne <Only time can tell whether the Dwarf Angel is directly pestering your Lion... If so they will have to be separated. Bob Fenner> Butterflies & angels/Compatibility/McDonalds on the reef 2/14/06 I know that no fish can ever be considered reef safe, but which butterflies are least likely to pick at soft corals? Everything I read tends to lean more towards them munching on worms and LPS corals. <If I were to take the CHANCE, it would be with a Raccoon Butterfly if yellow is what you are after. Second choice would be the Auriga Butterfly. I want a good bit of yellow for some reason and was also looking at a Lemonpeel angel as well. Do you foresee any great threat? <I have a false Lemonpeel in a reef tank causing no problems. They are easier to acclimate to prepared food than the Lemonpeel. All you are giving up are the blue eyelids. Compare to women...Two identical gals, one with blue eyes the other brown. The brown is much easier on your wallet...choose. James (Salty Dog)> Mixing Centropyge Angels - Research First!! 01/22/06 Hello Crew, <<Hello Jim. Ted here>> I just purchased a Half Black Angel about 2 inches in length. <<Given that you have a Coral Beauty already in your 75G tank, this was not a wise purchase. Return him if you can. Please read and research before purchasing. For example: http://www.wetwebmedia.com/dwfangcompfaqs.htm>> I set up a 10 gallon QT tank and filled it with water from my 75 gallon reef. I plan on keeping the angel in QT for about two weeks, however, I am concerned about feeding.<<You QT fish for several reasons including stopping the introduction of disease to a healthy tank. The QT period is also a time to acclimate and "fatten" the new purchase. Finally, the QT period also allows for the opportunity to cure a fish of Ich and other diseases. Because of this, the QT period is a month or longer. Please research an read. This will start you off: http://www.wetwebmedia.com/QuarMarFishes.htm>> There is no live rock in the QT tank. What would be the best choice for food? <<Please read here http://www.wetwebmedia.com/dwfangfdgfaqs.htm>> This is my first attempt at using a QT tank and although I have read info on QT tanks I am still not certain that I am doing what is best. <<What is your concern? Again, the purpose for quarantining is to prevent the introduction of disease and to provide an environment that is stress free for the new purchase. The Coral Beauty will most assuredly harass the new Angel.>> Additionally, I have read conflicting information (or maybe I simply don't understand) regarding Centropyge compatibility and the size tank needed. I currently have a 75 gallon reef with approximately 100 pounds of live rock. The two fish that concern me are the Yellow Tang and Coral Beauty. The Coral Beauty was about 1 inch when purchased and is currently about two inches in length. The Half Black that I want to add is just slightly smaller than the Coral Beauty. I really want to add this little guy to my main tank and would appreciate your advice.<<Two Pygmy Angels in 75g is asking for trouble. One will be unhappy is likely to hide all of the time and have a short life. If you keep the fish, QT it to ensure that the fish is as strong and healthy as possible prior to the introduction to the other fish.>> Jim Brown <<Good luck - Ted>> Betting The Long Odds (Mixing Two Centropyge Angels) 1/22/06 Hello Crew, <Hi there! Scott F. with you today!> I have a 75 gallon tank with approximately 110 lbs. of live rock. Can I put a Half Black Angel in this tank which currently houses a Coral Beauty. Information on your site suggests that housing a Coral Beauty and a Flame Angel together is a recipe for disaster but I did not find any specific reference for a Coral Beauty and Half Black. I live in Pittsburgh and my husband has already named this fish "Steely." Steely is in the QT tank and we were hoping to put him in the main tank on Superbowl Sunday. Any chance of a win here? <Well, the line on this match is that you'll probably have a conflict of some sort with these two guys. Just about any two Centropyge Angelfish species will have some problems if housed together in a system of this size. When mixing Centropyge Angels, you'll have a better chance of success if you start with juvenile specimens, added simultaneously. In addition, the tank should have rockscaping arranged in such a way as to avoid a continuous run. Better to have multiple "atolls" or aggregations, which provide each fish a small "territory". Adding a new Centropyge Angel into a system that has an established one is almost always a problem. Sure, you could attempt to mitigate the situation by re-arranging the rockwork in the tank prior to adding the new fish, in the hope that it will put both fishes on a level playing field, but that's a dice roll, IMO. My best advice would be to pass! On the other hand, you could buy another tank...LOL Good luck! Regards, Scott F.> Thanks for time and help. Valerie Mixing Centropyges 1/13/06 Hi Bob, <Actually you will be with me, Adam J tonight.> just wondering what your thoughts <Thoughts> are on mixing these two angels. <Okay.> I have a golden angel in a 42 hex with some soft coral; he's been in the tank for about six months and is very hardy. <Be aware that your experience with this animal is opposite to most. The majority of the ones I cared for while working for a large retailer failed to adapt to captivity, most refusing to eat (even live foods) until they were to weak and succumbed to starvation or diseases. Furthermore, while this animal is relatively small, to increase it's survival chances I recommend keeping it in large aquaria (lots of live rock, and a fishless 'fuge) to increase survival chances.> I also have a 75 gallon fish only with live rock, skimmer, and refugium, the tank has a potters angel, yellow tang, solar fairy wrasse, and a twin spot wrasse, my question is can I <I> put the golden angel in this 75 with the potters , <I would not miss to Centropyges in a 75 gallon, especially these two species.> the potters has been in the tank for four months and is very hardy also. <Heehee, see my comments above about the golden 'you can go ahead and mentally paste all of that in --here-.> The reason for the move is i <I> think the 42 hex is just two small for the golden <Me too.> the tank is only 30 inches and it just looks a little tight to me, <Yes.> thanks Ron <Ron, I agree the golden needs new quarters, but not cohabiting with your potters. Adam J.> Kim's Angels <Centropyge comp.> 12/13/05 Hi guys! Happy Holidays! My Christmas is turning out wonderful! My husband is getting me a new tank, a 96x24w x20h !! I plan to combine my 2 large tanks, a 125 with a Raccoon, an Iridis Wrasse, a Candy Hogfish, 2 Ocellaris Clownfish and 2 Argi Angels. And a 90 with an Arc eye Hawkfish, Salon Fairy Wrasse, a Blue Devil Damsel and a Coral Beauty Angel. I also have a Acanthurus japonicus [sp?] in qt. I may find my Arc eye a new home, I kind of like my Cleaner shrimp. I also may find a home for the Salon Fairy Wrasse, <Best to do this ahead of placing in such a large system...> he hates me, but that's a whole other story. Anyway I would really love to keep all my Angels if possible. I know its a risk, but I thought since they will be housed in an 8' tank and I will be placing them in at the same time that it might work. But I never make a move like this without consulting the 'Great Gods of fish Care'!! So would it be possible? Thanks so much for your help Kim <These dwarves should work out fine in such a large system. Cheers, Bob Fenner> This Angel Is NO Angel! 11/21/05 Hello, very helpful
& informative site. <Glad that you enjoy it! Scott F. here
today!> I recently acquired a mature 120 G FOWLR system and added
live rock so that now I have about 150lbs. I raised the rock into 2
piles using PVC structures that create cave-like hiding spaces.
<Excellent way of aquascaping!> The incumbents were a Porcupine
Puffer, Bicolor Angel, Tomato Clown, and Yellow-Eyed Tang, all between
3.5" to 4". They appeared to be getting along well when I saw
the tank set up at the former owners. Since I set it up, the Tomato
Clown has been hiding in the corners, but the other fish were getting
along well and eating. My LFS says the clown is probably stressed from
the move and should get more comfortable over time, but that has still
not happened after about 1 month. It appears that the Bicolor Angel is
harassing him. <Well, the fish can definitely become better
acclimated to new surroundings in this period of time, but the
harassment from another fish is definitely a factor that can affect
it.> I added a 5" Black Damsel (I believe it's a
Microspathodon dorsalis) and a smallish Snowflake Moray, my kids'
choices with LFS guidance. These fish have fit in fine with the rest so
far, and the moray seems to like the rock arrangement, but the clown
still has not improved. <It's likely to be a chronic problem if
the Bicolor continues to harass him.> I also inherited a Majano
anemone problem, so on the advice of the LFS and some web research, I
just added a 4" Raccoon Butterfly to control the anemones. The
Bicolor Angel almost immediately started harassing the Butterfly, and
he is staying away from the rock, which will keep him from doing his
job. <An unfortunate, but familiar trend with this angel, huh?>
He seems to have befriended the puffer, which works well since the
angel stays away from the Puffer, but whenever the Butterfly approaches
the rock, the angel shoots out to protect his turf. <"Protect
his turf" is a good description! Centropyge angelfish are
extremely territorial, and will defend a large area of reef from other
fishes. The fact that your tank is a bit crowded doesn't help to
reduce this behavior.> I realize 7 fish is too much for this size
system, especially since there are a couple of largish species (the
Puffer and Damsel), and am thinking that if the angel found a new home
(a shame since he's beautiful, very healthy, and a good eater) that
might make things better for both the Clown and the Butterfly. What do
you think? Where else should I look to reduce my bio-load (except the
Puffer, everyone loves him, and the Butterfly, since he has a job to
do)? <Unfortunately, removing the angel may be the one definitive
thing that you can do to reduce this problem. Personally, I would
remove the Damsel as well, but that is a personal opinion. Do consider
what the Butterfly will eat when the population of pest anemones is
eliminated...Will you be able to get him to eat prepared foods?
Although I'm in favor of biological controls for pests, where
possible, I don't like using Butterfly fish for this purpose,
because they may or may not adapt to a captive diet. Make sure to try
and wean yours to prepared foods...> Best Regards, Michael LeBauer
<My pleasure, Michael! Do consider removing the offending fishes and
re-thinking your bioload...Best of luck! Regards, Scott
F.> This Angel is A Holy Terror! (Centropyge in A Reef Tank) 11/9/05 Hi WWM Crew, <Hi there! Scott F. here today!> I've been a long term reader of your website, but never needed to ask a question. You are always very helpful, so hopefully my question can be answered. <We'll try our best!> A little background on my tank: 37 gallon tank that is 30" long, 780GPH return pump, 200 GPH spray bar behind 30 lbs of live rock, and about .5" to 1" of fine sand. I have a couple Acropora colonies, as well as many frags of SPS. I have a Hammer Coral, a Xenia, an Open Brain in the substrate, two Digitata frags, one Acropora tenuis frag, along with some others. <Neat mix for this sized tank..> I introduced a Flame Angelfish into my tank, about 5 days ago. For 4 days it only picked at little bits of hair algae (I solved the growth problem, but the existing ones were not all harvested out), and the algae on the live rock. I fed it some Formula Two food, but it only picked at a couple pieces, it ate some flake, but definitely not too much. I even fed it and my Clownfish some brine shrimp, and it at that too. Problem is, on the 5th day it ate all my SPS. By lunchtime, it had cleaned my Digitata clean, they were only skeletons rather than the usual fuzzy look. My open brain's "mantle" was very chewed up, showing green marks on it's pink/red surface where it got nipped. My Xenia retracted itself, looks like it was harmed. My Zoos were all closed. My Acroporas had maybe one or two polyps each open. My Hammer was untouched. Over $300 worth of damage done. I immediately took strawberry baskets and zip tied them to the top of my tank, submerged of course, putting all my SPS in there. I have to get more baskets to put my LPS and Zoos into. <Yikes...An all-too-familiar story, in my experience...> So my question is: Are my SPS just retracted or were they actually eaten? <Well, in all likelihood, some of the polyps are still intact, "hiding" in the corallites. However, with continued harassment from the Angel, they may not expand regularly, potentially dooming them.> Will this behavior continue to the point where my corals will die or be very unhealthy? Or, will it give up picking at my SPS and LPS and they will still be able to grow? <Gosh.. That's a question that simply has no definite answer. I have personally kept certain Centropyge species in reefs for years with no damage at all, but that does not mean that you or anyone else will have such success. For that matter, 3 years from now, my Angel may start plucking polyps from my corals. Maybe I've been lucky-who knows? It is a calculated risk, IMO. I have a friend that keeps a pair of Goldflake Angels in his 350 gallon reef system with tons of expensive SPS. He's had no problems so far, but I wouldn't be surprised to hear that they started tearing up corals at some point. "Conventional Reef Wisdom" indicates that the smaller Centropyge species, such as the "Cherub" (C. argi), "Fisher's Angel" (C. fisheri), or "Flameback Angel" (C. aurantonotus) are "safer". Even then, thee are no guarantees. Fishes are individuals, and may not conform to our behavioral expectations.> Are all angelfish like this? <Many do nip at corals to a certain degree. Some are simply foraging on mucus and algae associated with the corals and calms. Nonetheless, these are potential risks that you need to consider.> Reading I heard it was 50/50 chance of it being reef safe, and my LFS told me they were definitely 99% reef safe. <Really irresponsible for them to make such an assertion without "qualifying" it by stating that this was THEIR experience with this fish. The Flame is one of the more notorious Centropyge for coral nipping.> I know being reef safe, they will still nip once in awhile. Do you think it was just exploring and will shape up? <So hard to say. You'll just have to wait and see. One thing I have noticed is that hobbyists who have succeeded in keeping Centropyge in reef systems have categorically higher success in larger systems (100 gallons plus). Perhaps this is because these tanks afford greater "grazing" opportunities on live rock. Perhaps it's simply that there are more corals to choose from, and the damage to any one specimen is limited by this variety.> I can't catch it either with a net. Do you have any suggestions? I want to catch it and return it to the LFS unless there is reason that it won't kill my corals. <Again, no guarantees. You can use a "fish trap", but these fishes can be extremely difficult to extricate from an established tank without completely taking the rockwork apart. Work at night, and be prepared for some frustration.> Thank you! Art <My pleasure, Art. Best of luck to you.> Cyano Issues, Aggression From Centropyge Towards Tangs 11/01/05 Hi Crew, <Howdy Steve, Ali here...> I hope this query finds you all very well! I have been fighting a bit of Red Cyano lately and have made some progress by picking up more frequent water changes, cut back on feeding, and reducing phosphates. I read in several FAQ's from Anthony to "never allow thawed frozen pack juice" into the tank. I never really thought about what he was saying but maybe you could help me. I feed a large variety of food, however when I thaw my frozen cube food, I typically cut a small chunk of Angel or other "green" omnivore frozen food and also cut a chunk of omnivore frozen cube, in which I place in a small cup with a few drops of Zoe and tank water to thaw. Once thawed, I mix the food, turn off the pumps/power heads and dump the contents into the tank. I believe all of the thawed water, along with the Zoe that is in solution may be adding to my excess nutrient problems, do you concur? <Steve, consider keeping the following items near your feeding station/sink: a water bottle filled with ro/di water, a handheld fine strainer, and some Selcon (vitamin/essential fatty acid drops, MUCH better than Zoe). 1. Simply place the food you desire to feed your fish in the strainer; 2. Hold the strainer underneath the tap until the food is dissolved and excess oils are leached out; 3. Simply squirt ro/di water from the bottle directly over the strainer to 'clean' the food (final rinse); 4. Add few drops of Selcon over food.; 5. Feed fish. I would add Selcon at perhaps every 3rd feeding, however because you are having these excess nutrient issues, you can cut back totally from the Zoe/Selcon for the next month or so.> My fish consist of a 6" Bicolor Rabbitfish, 3.5" Orange Shoulder Tang, 2.5" Chevron Tang, 4" Bicolor Dwarf Angel, 5" Longnose Butterfly, and 30" Zebra Moray eel. These fish reside in a 250 gallon tank with 250 lbs. of Tonga Live rock, live fine Aragonite DSB, TurboFlotor Skimmer (producing lots of skimmate), 50 gallon wet/dry, 40 watt UV sterilizer, and refugium. In the refugium I have crushed live rock substrate, with mini PC (24 hours) on Caulerpa. <Sounds like a decent set-up you have going there Steve. You may consider upgrading the protein skimmer to an even more powerful model. Additionally, I would seriously consider increasing the water circulation and flow within the tank. This will help out tremendously with the red slime as well.> Second issue: My Bicolor Dwarf Angel is a recent addition to the main display tank and he is showing some signs of aggression towards the Chevron and Orange Shoulder tang. At one point he had the Chevron cowering in a cave and he would only come out to take a look and swim back in. Normally this Chevron is grazing off of the live rock non-stop and only hides at night when the lights go off. I know it is hard to say, but should this subside eventually? <Bicolors do have the potential to be somewhat overly aggressive towards tankmates. His aggressive behavior should however, subside shortly. Overall, they are not good choices for aquariums in my opinion. Just too finicky, perhaps improper collection methods.> The Bicolor Angel was in QT to settle in and never really fed well except off of the live rock and is still only grazing off of the live rock. Is the live rock enough to sustain him until he gets into the mix of feeding with the rest of the fish? <Hopefully he will do well. The LR should provide him with enough nutrients until he takes in prepared foods.> Your comments and help are greatly appreciated. Best Wishes, Steven <No problemo Steven, Good luck with everything! - Ali> <<No problema. No hay "problemo". MH>> Damsel Pestering Pygmy Angel 11/01/05 Hey Bob or Steve whoever gets this. <Ali here...> I have a 75 reef and for a while there was only a damsel in the tank (my parents took care of the tank this summer for me and that's all that was left) I just recently added a Flameback to the tank and the damsel is going crazy. He is attacking it and showing a lot of aggression. <Typical behavior for a damsel who has had a tank all to himself for a year.> I have the lights turned off now and there is over 100 pounds of rock in the tank. I don't know what else to do if this doesn't stop I think the pygmy will die. I can't trap out the damsel there is too much rock. Would adding another fish calm the damsel down so its just not the two of them? thanks any help will be great. Matt <Matt, you are in a dilemma here. More than likely, the damsel will not stop showing constant aggression towards the angel. Both fish more than likely have very similar body shape/size and diet. A damsel that has 'owned' and dominated the aquarium all by himself can be especially terrorizing towards other small fish. Generally speaking, the Flameback pygmy angels are an assertive fish that can hold their own with many other species of fish. However a newly added, un-QT'd fish placed within the grasps of a well-established, dominant damsel isn't really the best practice. Please consider removing some rockwork and gently trying to trap or catch either fish. I would not add anymore fish in the aquarium as the next fish you add will most likely suffer the same unnecessary fate as the angel. Good luck. - Ali>
