Mopani wood and a home for Gouramis   11/9/09
Hi everyone,
<Hello,>
I was hoping you could help me out with something. I'm in the process of setting up a new 29 gallon tank, and I bought two beautiful pieces of Mopani wood I'm planning to use in the tank.
<Cool.>
I've been soaking each in a 5-gallon bucket of dechlorinated tap water for a few weeks now, and been doing water changes in each of the buckets every few days. One of the pieces has a faint rotten-egg smell when I remove it from the bucket to change the water, while the other piece has no smell at all. Could this be harmful in any way?
<Is certainly odd.>
If so I'll definitely toss it--I don't want to risk any fishes' lives.
<Can you return the piece? Otherwise, try putting the wood in cistern of the lavatory, and after a couple of weeks, see if the flushing hasn't rinsed away any organic matter.>
Another question I wanted to ask you guys is about Gourami compatibility for this tank. I 'm hoping to center this tank around one or two female /Trichogaster trichopterus/, and I'm wondering what other fish would be compatible, as I've read these fish can be aggressive.
<Males are aggressive, yes; females generally pretty good.>
Several other sources I've come across have suggested harlequin Rasboras/ Rasbora heteromorpha /or white cloud mountain minnows /Tanichthys albonubes. /What do you think? Any stocking suggestions would be greatly appreciated.
<Either of these would be good. Rasboras prefer water on the warm side, Minnows on the cooler, so would choose depending on what other fish you had in mind. Corydoras for example like cooler water, so Minnows are a good choice. If you were keeping Angels though, they like warmer water, so Rasboras would make sense.>
Thanks in advance,
Shannon
<Cheers, Neale.>

Thanks so much, Neale! You've really helped me out!
<Happy to help. Cheers, Neale.>

Rainbow / Gourami question... comp.    6/29/09
I have a 30 gallon tank of 6 Rainbow and 1 Gold Gourami (Trichogaster trichopterus). They seem to get along okay, but I am worried the Gourami may get aggressive as it gets bigger. Do you think this combination will work?
<It's only the male Trichogaster trichopterus that become aggressive, and even then, it's usually towards other gouramis, or at worst, other fish of similar general shape, such as cichlids. Males have longer dorsal fins than the females, so it's quite easy to tell them apart when you have a bunch of them in front of you, but if you have just one specimen, you may want to look at some photos in aquarium books to see whether yours is a boy or a girl. In any case, I'd fully expect your combination of Rainbowfish and a Gourami to work very well. Cheers, Neale.>

Rainbow Shark Compatible with Gouramis?. 3/15/09
Hello,
WWM is my trusted source for aquarium advice.
<Thank you.>
I need advice regarding two tanks.
<Fire away.>
Tank 1: An established 37 gallon -tank with 1 large female Blue Gourami - 4 inches, 1 male Swordtail, 3 Otos, and 1 small ghost shrimp that must have stowed away on a plant since I have never bought one. The tank is heavily planted with a large piece of driftwood. Eheim Ecco 2234 canister and 150W Stealth heater.
I used to have 14 Cardinal Tetras in there also, but lost them all recently to a horrible bout of Ich brought in with a few new Cardinals. The other fish all survived - Gourami, Sword, and Otos. Since the Cardinals were lost, the Gourami hardly ever comes out anymore except to eat and the Swordtail hangs very close to her - they're an odd couple. I figure they need some dither fish.
<Possibly, but neither are "dither fish" species. Certainly not Swordtails, which live at the surface, so would *actually be* dither fish, rather than needing them. Likewise Gouramis live in thickly vegetated environments
close to the surface, and wouldn't really be nearby any schooling fish most of the time. So I'd be considering other factors first.>
Our local water is pretty hard with high pH - constantly around 8.
<Should be fine for a wide range of fish. Perhaps not Cardinals though, which do seem to prefer water at least only moderately hard, and ideally soft.>
I don't want to mess with Cardinals again so I will gradually add in about 10-15 Harlequin Rasboras, which will be hardier.
<Can't say I've ever found Harlequins to be hardier than Cardinals. Both are pretty much soft water fish. When it comes to hard water tetras, I'd be looking at the "old reliables" like Pristella (X-ray) tetras or Lemon tetras. Even better, look at the Celebes Rainbowfish, Marosatherina ladigesi. This fish thrives in hard water, and has the neon blue you want, though in combination with yellow rather than red. It's a cracking little fish, and like most rainbowfish, if you buy good specimens, they're really very reliable and long-lived.>
I currently have 6 Harlequins cycling a new 10 gallon tank, which will move into this bigger tank in a few weeks. I would also like to add 2 or 3 Pearl Gouramis (1 Male, 2 Females) to the 37 gallon tank.
<OK. A male Blue Gourami would probably have a fit, but a female should be fine.>
Anyway, I just got a very small Rainbow Shark a few days ago - I caved in to my 13 yr old son who has bugged me for months about getting a shark.
This was our compromise, since he wanted Balas and that was out of the question.
<Quite.>
The Rainbow is a little smaller than 2 inches. I purposely got a small one, so the other fish would be dominant - at least until he is full grown.
<Wise.>
I still have time to get the Pearls before the Rainbow becomes more mature and established in the tank. Right now, he kind of hides in the plants by himself, but is coming out more and eating well. The Gourami has not shown any interest in him at all, which is good, I guess.
<Rainbow Sharks do tend to be amongst the mildest of all the Sharks. In general, they're only aggressive towards other shark-like fish, including things like loaches.>
My question for tank 1 is this - Do you think the Rainbow will be compatible with the Rasboras and the Pearl Gouramis - that I plan to get in the next 2 weeks?
<Always a gamble with Sharks, but in this case, I'd certainly risk it.>
Any suggestions you can offer will be welcome. And no, we can't get rid of the Blue Gourami - she's my daughter's that we raised from an egg....parents were relocated.
<Cool.>
Tank 2: In this tank which is currently being cycled with 6 Harlequin Rasboras (1 week now - fish are doing well and Ammonia, Nitrites and Nitrates are all 0 daily. Filtration: AquaClear 20 and a 50W Stealth
heater. I was considering a pair of Blue Rams. However, after research, I am coming to the conclusion that these will not be the right fish for this tank.
<Would agree. Mikrogeophagus ramirezi is one of the more demanding fish species, and many aquarists completely fail to keep them alive for any substantial length of time. A much, much better choice is its close
relative the Bolivian Ram Mikrogeophagus altispinosus, a species that thrives across a wide range of water chemistry conditions and, most critically, at regular temperatures (Blue Rams need much hotter water than
most tropical fish like). There are few fish I recommend without reservations, but Mikrogeophagus altispinosus is one of them. It's slightly bigger and perhaps a little less gaudily coloured, but mature fish are
still very beautiful and the fact they're hardy (by dwarf cichlid standards, at least) is a major plus.>
Most of what I have read says they need more territory and softer water with higher pH - like my Cardinals, which were fine to a point, but as soon as something upset their balance, they couldn't bounce back like the other fish did.
<Precisely.>
My other thought was to put in a pair of Labidochromis (Electric Yellow Cichlids). Our water conditions would be more suitable, but this tank size is also too small.
<Agreed; these are superb fish for a Mbuna community tank, or possibly mixed in a community with robust rainbows and barbs, but like all Mbuna they need space.>
Question - What other fish or fish combinations could you suggest for a 10 gallon tank that is more suited to higher pH and hard water such as we have in our local area? I'd like to give them the optimum living environment considering it will be such a small environment.
<For a 10-gallon tank, if you're up for a challenge, and want something quirky, consider Tanganyikan Shell Dwellers. These are small (typically an inch or so) cichlids that live in empty snail shells, sometimes in pairs,
but usually as harems. Lamprologus ocellatus and Neolamprologus multifasciatus are probably the two most widely traded species. Besides looking good, these fish have the usual fabulous spawning behaviours we
expect from cichlids, but scaled down to the point where males barely show any interest in things more than a couple of inches above their shells. As such, you can add some genuine dither fish to the mix in the form of
suitable hardwater species; Endler guppies for example are popular choices.>
We also have a Betta in a 1.5 gallon tank - quite old (almost 3 years old) and may soon be on his way to a happier hunting ground.
<A heck of an age.>
Your help is greatly appreciated.
With kind regards,
Sandy
<Cheers, Neale.>

What's Up w/Gourami Swordtail couple? Re: Rainbow Shark Compatible with Gouramis? (also, stocking a 10-gallon) 3/15/09
Dear Neale,
<Sandy,>
Thank you very much for the speedy reply. Much appreciated.
<Most welcome.>
Have taken in all you wrote and will seriously consider the Celebes Rainbowfish although I have never seen them in my area. I was very excited to learn about these fish that I have not read or about before. What I have just read about them on the web suggests they may be a bit finicky and I found more than a few articles that suggest adding aquarium salt. Is this your opinion as well and would that be alright for my other fish - the Gouramis, Sword and Otos?
<They don't need salt. This is 'old school' from when they were considered brackish water fish. What they appreciate is a steady pH, an at-least moderate amount of carbonate hardness, and lots of oxygen. Excessively high temperatures should be avoided; 25 C (77 F) is ample. Most problems with this species come down to keeping it in stagnant, overheated tanks.>
Also as you said - I need to consider what else is going on with my Gourami and Sword...
<Quite.>
History - They were previously in a healthy, well-planted 20High tank and I moved them into the 37 gallon tank last Xmas. She has become more skittish and typically hangs at the bottom of the tank - but she did in the 20 gallon as well. The Swordtail comes out more and hangs at the top more than the Gourami, but they both hang more at the bottom of the tank than at the top. The bottom of the tank is more densely planted and there are more places for her to hide, but I suspect also that the Eheim makes more surface movement than the Aqua Clear in the 20 gallon that she was accustomed to before. They were definitely more active in the tank when the Cardinals were around though. This tank is much deeper, so there is more open space in the top levels of this tank than there was in the previous tank. Pennywort, Rotala and hairgrass are growing in nicely, so that may help to bring her to the top more as they fill out the top levels more.
<Sounds promising.>
I also have two young (4 and 3 yrs old and very active) children and the tank is located in a fairly high traffic location. She sometimes darts when the kids run by, but not always and this is the same location as the previous tank. The only other change is the substrate. I had pea gravel before and now have eco-complete. Oh - I also add Flourish Excel Liquid Carbon every other day, which I didn't in the previous tank. Would that make a difference to her behavior/behaviour? It seems to make a big difference to the plants.
<Substrate shouldn't be a factor for the Swordtails. Banging about outside the tank could be an issue though. Adding a couple of female Swordtails may help; females are gregarious and, unlike the males, don't fight for territory.>
Regarding adding the Pearl Gouramis. Alas - even though the males are showier, I may just get 2 females to keep things sane - since I don't really want to mess with spawning in this show tank.
<OK. But I've rarely heard of the males of this species causing problems.
Pearl and Moonlight Gouramis are both towards the peaceful end of the Gourami spectrum.>
I have always like the look of Diamond Tetras - What do you think about a few - 4 to 7 Diamond Tetras - Moenkhausia pittieri - if I can't find Celebes here? They would be in place of both the Pearl Gouramis and the Celebes.
<Diamonds Tetras are lovely fish. When happy and fully grown, they're exceptionally attractive and live for several years. Sometimes they don't adapt to hard water though. Supposedly, farmed specimens tolerate hard water acceptably well, but wild-caught fish don't.>
Tank 2: I will look for Bolivian Rams - Great thinking! I suspect they may be available here and sold instead as Blue Rams (for more money) by less reputable shops....But I have not seen "Bolivian Rams" in local shops here.
<They are in the trade, but admittedly the common Rams are more widely sold, though I'd argue because of high turnover: few aquarists keep common Rams alive for more than a few months! Bolivian Rams should live 5+ years without problems.>
Looking forward to your reply.
Gratefully,
Sandy
Whose husband wishes he were a fish.......
<How odd. Cheers, Neale.>

Thanks so much Re: What's Up w/Gourami Swordtail couple? Re: Rainbow Shark Compatible with Gouramis? (also, stocking a 10-gallon) 3/15/09
Neale,
Thanks again - so happy I have not more serious issues with my fish today.
<Great!>
Your advice and suggestions are thoughtful and most appreciated. All will be considered as checkbook and availability allow.
<Very good.>
Will probably not go with female swords....until we're ready to deal with all that spawning - I have a 4 yr old budding naturalist who would really enjoy it though - she knows all the Latin names of our fish and plants!
<Outstanding!>
The hubby thing - every single time I am at the fish tanks, he sings wistfully, "Oh - I wish, I wish...I wish I were a fish!
<Hmm... not quite Henry Rollins, but okay.>
He complains that he dropped down one more rung on the ladder behind the children - Wah Wah Wah....
Wishing you a lovely day!
<I hope so too; my sister is in the middle of giving birth to her (first) baby, so with luck, I'll be an uncle for the first time at "close of business".>
Sandy
<Cheers, Neale.>

Add pair of three-spot gouramis?  3/8/09
Neale,
I have a 20 US gal tall tank w/ 1 dwarf Pleco and 10 glass fish. I'm in the process of slowly but surely adjusting the tank to a live planted tank.
Other than the tannins from the new drift wood turning the water reddish, water parameters appear to be in normal range. I know the reddish water will resolve over time as normal water changes are made. I've been approached by a neighbor who is trying to find a home for two blue gouramis (presumably Trichogaster trichopterus). One is a male and the other a female. My reading here and on other sites suggest varying minimum tank sizes - some say 20 gal and some say 30 gal. Is my tank big enough to peacefully house these pair along w/ my other inhabitants? I know Gourami
and glass fish are good for one another. just wanted to make sure my tank was big enough before I invite them to stay.
Thanks - as always!
Kristi
<Hi Kristi. I'm not a huge fan of Three-spot Gouramis (indeed, Trichogaster trichopterus) in community tanks. The females are reliable, but the males less so. They're hardy enough that being kept in a 20 gallon tank won't cause health problems, but the males can become so territorial they chase everything in sight. In bigger tanks this is less of an issue because there's more space. But in a 20 gallon tank, it's risky. I'd perhaps inquire why these fish need a new home: if they're terrorizing her other aquarium fish, your answer will be right there. If you watch the fish and they seem perfectly settled and peaceful, then you might be okay. Glassfish and Plecs should be fast/armoured enough to handle a Three-spot, so the gamble isn't too bad from their perspective, but if you add more delicate species in the future, like Angels or Guppies, that's when things become problematic. In short: 30 gallons best, 20 gallons adequate; females peaceful, males sometimes waspish. Cheers, Neale.>

20 Gal Set-up 12/28/08
I think this is way over the limit but I thought I would try anyways.
1 Gold Gourami
<Mmm, do keep an eye on this Trichogaster... might become a bully here>
1 Dwarf Gouramis
1 Bristlenose Pleco
2 Upside-down Catfish
<Mmm, are social animals...>
3-4 Cherry Barb
4-5 Neons
I have two filters and plenty of plants and caves for hiding and such.
Think I could pull it off? The tank does not have the fish in it yet. If this set-up is not good, do you have any suggestions. Thanks.
<Mmm, I'd likely leave out the Gold Gourami... but otherwise, this mix should work here. Bob Fenner>

Gouramis as "the butler"
The angelfish are both babies, and SEEM extraordinarily peaceful. In regard to the Gouramis, I had to return the gold Gourami to the store, as he was terrorizing the powder blue one, but he would have been in the tank a full 24 hours before I added the powder and realized they couldn't co-exist.  He only seemed aggressive towards his own kind, but I suppose he could have done it.  Also, the Danios are about the same size as the tetras and they play chase with each other quite a bit-although neither seems to dominate.
That said, however, the tetras ranged in size from babies to adults, and I think the one that got killed was one of the smaller ones.  Could one of the Danios have done it?
<If the fish was weaken or damaged by another fish then the other fish start looking at the wounded fish as food. At that point they are probably all guilty.>
There's still 5 out of 6 in there, though, and I would think that if it were a fish still in the tank that he would have taken out another one. I plan to clean gravel and change water today, so I guess it's possible that I'll find his body and find that he died of natural causes-although I still imagine he'd be viewed as food and eaten already if that were the case.  Is that correct?
< I think any dead fish soon becomes looked at as food by the others.-Chuck>

Gourami shredding goldfishes

I have a 20 gallon long with 3, 4 inch goldfish in it. And 1 blue Gourami. I have had the tank for 2 years with no major problems. About 2 months ago, I bought a shubunkin fish. It swam with the pack almost immediately. This morning when I woke up I noticed that my blue Gourami was chasing around one of my 2 year old goldfish whom he's lived with all along. His fins are almost shredded and he is floating sideways. I love my fish dearly and am very confused at why this is happening.
<Blue/two-spot/Opaline/gold Gourami (all color morphs of Trichogaster trichopterus) tend to be rather aggressive.  Chances are, with the addition of the new fish, the Gourami felt crowded, and decided to, 'uncrowd' the tank - his way.>
I put my Gourami in another tank for now.
<Good.  Keep him separate from the goldfish, or this'll probably happen again.>
Can I save my Fish in time?
<Hopefully!  Keep your water quality as good as possible, keep up with water changes, and stay on top of ammonia and nitrite.  It might be a good idea to medicate with an antibacterial like Kanamycin sulfate (Aquatronics sells this as "Kanacyn") or Nitrofurazone (Aquatronics sells this as "Furacyn").  Watch him closely for bacterial infection if you don't medicate; wounds are an open door for illnesses to set in.>
All the other fish are fine. And my pH and ammonia levels are normal.  Katana
<Wishing you and your goldfishes well,  -Sabrina>

Gourami question
Hi all,
<Hello Mark>
Can't say enough good things about the amount of help you've given us fish lovers.
<You would, perhaps will do the same>
I've got a 10 gallon freshwater tank.  Some fish have come and gone, but the mainstays in the tank are a 2 1/2 inch Gold Gourami and a 2 1/2 inch Iridescent shark.
My problem is that I've recently begun to add fish to the tank...I added a 2 inch silvertip shark who gets along great with everyone one, but the Gold Gourami seems to be attacking a 1 1/2 inch Blue Gourami that I added.
<Mmm, really, the root of the difficulty here... the size of the tank... too small>
The Gold Gourami has always been aggressive to smaller fish (small leopard puffers and mollies).  I figured that adding a larger sized fish (the Blue Gourami) would help to calm the Gold Gourami down, but he just cant seem to break the habit of chasing all of the other fish around the tank.
<It might work... to isolate the original... gold Gourami... in a breeding trap, or even just a good sized net, hung on the corner of the tank... for a few days... This often re-sets the "dynamics" in a system>
Barring total isolation of one, is there anyway that I can keep the Gourami's together?  The attacking never goes beyond chasing and the occasional nip, but I'm just afraid that the stress will do him/her in.
Thanks for the help,
Mark
<You are likely right... try the isolation trick... and if this doesn't work? Perhaps a larger system? Or a trade-in. Bob Fenner>

Blue Gourami Aggression
I have a blue Gourami fish and just the other day it started chasing around my 2 Bala sharks. When I bought them they were in the same tank.
And the Gourami doesn't seem to care about the other fish in there. I did hear that blue Gouramis can be territorial but at the same time peaceful. Do you think that the Gourami is really out to kill the Bala sharks?
Nick
<Well, some Trichogaster Gouramis do "turn mean", but Bala Sharks are fast and smart... able to stay out of the Gourami's way... if the tank is large enough. Am sure you're aware of how large these minnow-sharks get, their propensity for jumping... Bob Fenner>

Three Spot Gourami Aggression 1/15/08
Hi Bob,
<It's Neale here tonight, actually.>
I have read many of your answers to questions on aggression often encountered with the Three Spot Gourami and found them very informative.
<Yes, male Trichopterus Trichogaster are indeed very aggressive fish. Not recommended for community tanks.>
However, there are some details I would like to be more clear on. First, a bit about my tank. It is a 21 US Gal tank containing 3 Otos, 3 Zebra Danios, 1 Betta fish, 1 Three Spot Gourami and 1 Dwarf Gourami. There is a porous rock, a plastic plant (waiting to introduce real plants) and a ornamental castle as well. The Dwarf Gourami was added 2 months following the Three Spot Gourami. Upon introduction of the Dwarf Gourami the Three Spot was aggressive towards it almost instantaneously.
<No surprises there at all.>
I let them be for about 20 min or so, but the Three Spot was relentless in its pursuit of the Dwarf. Finally, I had to separate the two since the Dwarf was beginning to suffer immensely.
<I bet.>
I read on your site to isolate the more aggressive fish for about a week and then see what happens.
<Hmm...>
I am wondering how effective is this?
<With Trichopterus Trichogaster, not effective at all.>
Even in isolation in a homemade colander, you can see the aggressive behavior of the Three Spot whenever the Dwarf is close by.
<Indeed.>
If this does not work will heavily planting the aquarium be beneficial to curb the Three Spot's aggression?
<Nope.>
Or should I add a couple of Three Spot females or instead add a couple more Dwarf's.
<Nope. These two species are simply not compatible. Certainly not in a 20 gallon tank.>
In regards to the Dwarf, its tail fin is severely damaged (~1/3 of it) as well there is some damage to its ventral and dorsal fin. Will the fins heal and grow back?
<In theory, yes.>
If so, how long on average does one expect the healing process to take?
<Couple months, assuming it doesn't get Fin Rot in the time being.>
I look forward to your responses, you have a great site!
Ryan
<Hope this helps! Neale.>

Re: Three Spot Gourami Aggression 1/15/08
Hi Neale,
<Ryan,>
Thank-you for your quick response. It is too bad that some sites do say that the Dwarf and Three Spot Gouramis are compatible, otherwise I would not have purchased the Dwarf.
<Indeed. Female specimens of Trichopterus Trichogaster get along fine with the Dwarfs; it's the males that are mean!>
A couple more questions.
<OK>
Is the Dwarf compatible with the Pearl Gourami?
<Should be; these are generally very mild animals.>
What other Gouramis would go well with the Three Spot?
<Moonlight Gouramis (T. microlepis) should work well, too. I'd avoid mixing Dwarfs with other Colisa spp though.>
Thanks Again,
Ryan
<Happy to help, Neale.>
