Somethings nibbling my Sarcophyton! 04/11/2008 Hello Crew, how are you all on this fine day! <<Hello Simon, Andrew today>> Since Bob helped me rather well last time I am seeking some advice on a new problem. I have attached a picture of my leather coral (Sarcophyton) that last night appeared with bite marks all around it. This all happened over a short period. Two days ago it was fine, all polyps out and reaching up to the light, yesterday it looked like this. <<I agree, bite marks>> It has been a little 'in and out' over the last month, but I had put that down to the usual 'sloughing' of surface skin that they do every now and again. <<Sure>> I have three possible fish culprits, a Niger Trigger, an Emperor Angel, and lineatus Tang. I say the tang because I noticed it nipping some Zoanthids yesterday. Do the marks look like fish bite marks, and if so which is most likely? Or do I have an unseen invertebrate (Nudibranch?). I am sorry that my picture is not great, I am in the lower leagues of photography I am afraid, still looking for promotion but without the funds to buy a star player (a top camera). Maybe I will have to ask the chairman!! (woman!) <<Yes, all three of those fish will have a tendency to nip coral. In reality, i would be tempted to go for the Angel or more likely the trigger, as the niger trigger should only be housed in Fish Only tanks>> Only the surface layer of the coral has been eaten (Or is it diseased?) it does not go all the way through. It looks like there are little green blobs around the wounds. Is this likely decaying tissue? I could not get a close enough photo. They do not look like Nudibranchs, but I am no expert which is why I am writing this! <<I would not suggest Nudi involvement>> If it is my Emperor then is the only solution to remove the coral? The Emperor is going no-where as it is the most majestic thing this side of the milky way! <<Of course, the choice is yours when you have confirmed the biter. Remove the offending fish, or the coral>> Thank you very much, Simon, England <<Thanks for the questions, hope this helps. A Nixon (also in England)>>

Uhh... what's that to the lower left? Source. RMF.

Re: Somethings nibbling my Sarcophyton! Further  04/14/2008 Thanks Bob, those are 'hairy mushrooms', Rhodactis. Do you mean that this could sting the others, or possible allelopathy at all? I was not aware that these had large/ extendable nematocysts please advise should I move this coral away from the Sarco's? (and therefore everything else as well?) Thanks a lot, Simon, England <Yes... sorry for the lack of clarity. I am indeed speculating that the Corallimorphs are mal-affecting your Sarco... note the arrangement of damage on the toadstool. I would at least separate these Cnidarians... a good foot or more between. Bob Fenner>
Re: Somethings nibbling my Sarcophyton! Further  04/14/2008
Thank you again Bob, will do. Simon, England <Ah, good. Please do send along a follow up in a month or so. Cheers, BobF>

Re: Somethings nibbling my Sarcophyton! Further  - 04/14/08 Will do! I don't know if you saw my previous answer to Andrew, but I thought that it was quite interesting that the 'green' blobs (not a scientific term I know!) were actually the polyps. <Ahh! I did see, yes> Good health to you! Simon, England <And you, BobF, Ca>

Cauliflower Colt Coral Dying -- 03/19/08 Hi, <<Hello, Brad>> I am new to managing a salt water aquarium and I recently purchased the above which I understand can also be called Soft Finger Leather Coral. <<Hmm'¦one brings to mind a Cladiella species and the other a Sinularia species 'but then, that is the problem with such 'common name' usage>> When we first introduced it to the tank it seemed to fill out and stand quite erect. Now it is limp and small with (a) some white spots on some of the branches; and (b) the base looks like it is separating from the rock it came on and tearing right where all of the branches start. <<Very bad 'this organism is likely dead and decomposing/disintegrating 'I would remove>> I introduced 3 other corals at the same time (Star Polyp, Toadstool Mushroom Leather, and Devil's Hand Leather) and they don't seem to be an issue. <<The Colt Coral may have been doomed before purchase/from the start>> I also have a Ritteri Anemone, <<Mmm'¦do read on our site re mixing Actinarians with sessile inverts>> several fish, and other inverts that seem fine and my water seems fine too (nitrate is climbing a little - could this be the problem and if it is, how do I manage it back?). <<The elevated Nitrate is probably due to the decomposing coral. Remove the dead coral and perform a partial water change>> Your guidance would really be appreciated. Thanks, Brad <<Based on the information provided, I can only speculate that the Colt Coral was already doomed from damage during collection and transport, or something in the system poisoned it (and was the 'last straw' in its weakened state), or maybe, it was placed too close/stung by the Anemone. Regards, EricR>>

Re: Cauliflower Colt Coral Dying -- 03/19/08 Thanks Eric. <<Quite welcome, Brad>> I'm going to move to my quarantine tank and see if there is any hope but will get it out of the main. <<Ah, good!>> Not sure if you can help me here but I'm not thrilled with the local retailer I've been going to as in the last 3 months I've had (a) 2 ocellaris clownfish die in quarantine before introducing to the main tank; (b) 1 4 striped damselfish get parasites (Ich I think) within 24 hours of buying - luckily we got rid of it and he's fine now; (c) a cleaner shrimp die in less than 24 hours after being in the main tank (didn't go into quarantine); and now (d) the coral problem. <<I see>> My water tests I've done at home and had the retailer do are all very good so I worry the retailer isn't providing the best quality and there are no guarantees with them. <<Mmm well, the fact that 'you' are 'new to saltwater keeping' aside'¦to be fair, it may not necessarily be the quality of care/service provided by the retailer 'but rather the quality of the care given to the livestock 'provided to' the retailer. Still 'doesn't help you/change facts 'if this is the case>> I understand marine aquariums are tricky but I am somewhat concerned as I get different answers from many staff. <<You will find the same here 'the hobby is ripe with opinion>> My question is do you have a list of retailers (physical or mail order) that are known to be of extremely high quality in the Toronto area of Canada (or can mail order to Canada)? <<Mmm, none that I have dealt with directly 'but Big Al's in London, Ontario is reputed to have quality livestock/dry goods/service 'and it may be worth investigating Reef Solution in Laval, QC and Aquaria Canada in Hull, QC. As for mail order of saltwater livestock, I don't think anything from the US is going to be economically feasible for an 'individual''¦but within Canada, JLAquatics in Vancouver is favored by some, and I have heard mention of Gold Aquarium in Calgary. A quick keyword search of the NET re the store names should yield more detailed information>> Any advice is welcome. <<Hope it helps>> Thanks again, Brad. <<Happy to assist. EricR>>

Sinularia flexibis, hlth./comp.  -- 03/18/08 I added a large healthy Sinularia Flexibis (spaghetti coral) from LiveAquaria to a 90g reef tank (other coral inhabitants: brown toadstool mushroom coral (Sarcophyton sp.), green toadstool mushroom, (Sarcophyton sp.), Ricordea mushrooms, other assorted mushrooms, pipe organ coral. While the spaghetti coral is thriving, the soft leathers (Sarcophyton) are not; they have retracted their tentacles and appear 'slimy,' 'flat' and 'collapsed/closed'. <It's probably that you have too many different types of soft corals and leathers in the same tank. Exactly how many is too many? I honestly couldn't tell you. We usually don't find out until something starts suffering.> (I have rearranged so as to modify light and water flow conditions to no avail. They are additionally often covered in the sweeper tentacles that extend from the spaghetti coral at night (Very long webbed strings that can extend half the length of the tank) that have presumably broken off on it. Are such sweeper tentacles deleterious to the health of the (soft) corals <likely so, to some degree or another> - or are my concerns misguided such that I should instead be looking for some other potential problem (everything tests out fine so I am thoroughly perplexed by the change in condition). <These animals produce all kinds of chemicals and toxins, it's often impossible to predict exactly how one coral will affect all others under a given set of circumstances. But generally, this sounds like an allelopathic problem of some sort to me.> Additionally, a change in location of the leathers is not thought possible given the size of the tank and rock wall positioning - and in any event, unless perhaps placed on tank's bottom where lighting may not be sufficient, all locales likely within reach of such long string-like protrusions from the spaghetti (if that is in fact what is causing the disturbance). <This could very well be the case (especially if they are mesenterial filaments).> Note: a frogspawn introduced at same time as spaghetti also died - <LPS corals are thought to be especially vulnerable to leather coral toxins.> although I suspect the butterfly may have picked at it sufficiently (have been conscientious in selecting coral species that would not be harmed by the butterfly - <Good start, but the next step is to think more carefully about selecting corals that will not harm each other. At this point, the only advice I can give you (aside from removing the S. flexibis) is to run a lot of activated carbon.> this was a surprise to me, introduced based upon the advisement of a professional reef-keeper / maintenance person). Thanks! Mike <De nada, Sara M.>

Unwell Coral, Alcyoniid allelopathy   3/9/08 I have a soft coral in my reef tank which was absolutely flourishing until a couple of days ago when we introduced three new corals. <Oh oh... it's losing> I think it is a leather coral (soft) maybe something called Devils Finger. It retracts quickly when the lights are switched off, but in the morning comes out and is quite large with polyps extending from the fingers. We have had it for a couple of months now with a couple of other sorts and it was growing rapidly. It was a soft pink in colour. <Mmm, might be artificially dyed> This week we introduced another leather coral, a bit like a toadstool, a leather coral which is flat, and a star polyp coral. We attached these fragments to our live rock using Milliput. While doing this the Milliput seemed to leak a foggy substance (small particles) and the Devils Finger (If it is that) retracted quickly and went very mauve in colour. It has remained like that now for four days, despite water changes and a thorough clean of the external filter. We have put Poly Filter and Carbon in the external filter. <Good> Could you have any idea what has upset our coral which was so well established and doing so well. Will it recover. I shall be very glad of your advice. Byan King ( In UK) <In a word, allelopathy. Read here: http://wetwebmedia.com/cnidcompppt.htm and the linked files above... and then on to the "Compatibility" FAQs files of the Cnidarian groups present... via the index or search tool.

Growth on coral question   3/5/08 Hi, My colt coral has a white growth on the side of it. I have noticed since it started growing about 2 1/2 months ago, the health of my colt has been off. I'm not sure if it really has anything to do with my colts health or not, but it showed up at the same time it started not doing as well as it had been. ( I have had the coral for 5 months) Thought I had lost it about a month ago, but it is slowly bouncing back and is feeding more hours a day. <Good> The white patch also "grows and shrinks" during the day like a coral does. This patch has also really had a growth spurt in the last 2 weeks. Insight anyone, to what this might be...good or bad? Sal. 1.025 Calcium 460 Alk 5 PH 8.2 Nitrite 0 Nitrate .02 Ammonia 0 Silicate 0 Phosphate 0 Thanks for any info, Katie <I would look closely... perhaps a Nudibranch predator at play here... Could be an ongoing infectious agent... there are folks (esp. commercial) who would "cut to the chase" and frag this Alcyoniid, excising the troubled area.

Dyed coral -02/25/08 Crew, Thank you in advance. On the way home from purchasing this coral today (picture attached), it suddenly occurred to me that it is most likely dyed. There is probably a reason I've never seen one this color. <Indeed, this is an unnatural pink for a leather coral. Please see here: http://www.wetwebmedia.com/dyedcorals.htm> I believe it is some sort of leather as that is the feel it has. My question is will it harm any of my other tank inhabitants? <The dye or the leather? If the tank is a decent size (not a nano), the dye probably won't harm anything else (but it's a good idea to run some activated carbon anyway). However, leather corals in general (dyed or not) can be toxic to stony corals.> I realize it is probably doomed itself, but is that the extent of the threat? Thank you, <No, it's not doomed. But as it recovers, the pink color will fade. It's hard to say what color it will be after the dye is gone, but hopefully it will survive and you'll find out. :-)> Ben
Sara M.>

Yowzah, dat's peenk! RMF.

Yellow Leather Coloring Issue -02/21/2008 Good Morning WWM Crew, I¹m writing today to inquire more about a coral vanity question rather than its health. <Not to get too philosophical, but shouldn't these be more one in the same? How "beautiful" could any unhealthy coral be?> I got the most spectacular yellow Fiji leather a few months back. As you can see in the picture attached it is sunshine yellow. (Forgive the unhappiness of the coral, the picture was taken only moments after introduction into my tank). <Please see here: http://www.wetwebmedia.com/dyedcorals.htm> I have it situated approximately 5² below the waterline under 4 54W T5 bulbs. (1 white, 2 Blue, 1 Purple). Over time it has gradually become more brown in color towards the edges of the skin and the polyps. <Hmmm, this tends to happen as dyed corals recover.> It is growing nicely and extends its polyps daily, <awesome> but it just isn¹t the same spectacular sight anymore. <Sure it is... but it's spectacular in a different color now.> Is the discoloration from lack of light or too much light? I¹ve also attached a picture of the whole tank so you can see that it is placed far enough away from any other corals that might be causing chemical warfare. <Well, as far as chemical warfare goes, I'd worry more about the leather coral(s) hurting the stony corals. Leather corals can be quite toxic to many stony corals.> I¹m interested to know your opinion and your recommendations for how to get the old color back. (Please note these are old pictures and do not accurately portray the color now) <The best advice I can give you is to care for the coral as best you can and to maybe be a bit more "flexible" in what you consider beautiful. Or, if you really must have a bright yellow coral, try to find one that's naturally that way (rather than artificially dyed that color).> Sincere Regards,
Jessica L.
Sara M.>

Sarcophyton elegans... or dyed? The latter. RMF.
