Poorly Gourami (Red Robins; taxonomy, health)   2/11/09
Hello Crew!
I've had a look all over the internet and at your recently answered question but haven't found anything that really applies to the problem my Gourami has, so i hope you don't mind me emailing!
He's is a 'red robin' honey Gourami who i have had for about 6 months and always been well. Yesterday i came home to find him sitting at the bottom of the tank with a slightly rounded underside - just around where i assume his swim bladder is, at the base of his feelers. He was moved about a week ago from my previous 30 litre tank to a new 120 litre. I have given the tank a water change and the water results are still within the normal parameters (I'm going to test again this evening). I've also put some peeled peas into the tank but he doesn't seem to be interested in them. He is currently sitting at the bottom of the tank and taking the occasional trip to the surface for a quick gulp of air, then sinking slowly back to the bottom. Also, when he's swimming he seems to be finding it difficult and his lips look a bit greyer than usual.
The only other thing apart from the new tank, that has changed, is that i bought 3 small Corys at the weekend, one of which died within 48 hours after barely moving. My second honey Gourami is still behaving absolutely normal and the 2 remaining Corys are perfectly fine. Can you give me any advice? Should i quarantine him? I've also been reading
about some antibiotics that aren't compatible with gouramis and others that shouldn't be used when Corys are in the tank!
Any info you could send would be great - i can't get to my local fish shop until tomorrow evening.
Many thanks for your time

<Hello Jess. Red Robin Gouramis are curious fish because nobody really knows what they are! Several different fish are sold under the name, most commonly a hybrid between Trichogaster chuna and Colisa lalia, often, though not always, fed with colour-enhancing foods to make their colours brighter than they actually are. Quality is extremely variable, and like a lot of fish mass produced in Southeast Asia, bacterial infections can be a real problem because of the widespread use of antibiotics on the fish farms. Whilst they don't seem to get the dreaded Dwarf Gourami Iridovirus (DGIV) they aren't the hardiest of fish and lifespan is often rather short.
Sometimes Red Robins are merely red-coloured Colisa lalia, in which case DGIV is a risk, as well as all the usual bacterial problems Dwarf Gouramis are prone to. Inbreeding is an issue here, and indeed with almost any fish
that doesn't have its wild-type colouration. That's a point worth reiterating: when you shop for tropical fish and you decide to get a "fancy" form, you're doing a trade-off between genetics and physical appearance. Finally, some Red Robins are fancy Honey Gouramis. Again, inbreeding is an issue, but on top of that you have the problem that
Trichogaster chuna is simply not a fish that does well in hard water, so unless you have soft, slightly acidic water conditions, it's a species to avoid. Having laid out the problems identifying the fish, treatment is somewhat difficult to suggest. DGIV is impossible to cure, so if that's the case, there's nothing much to do beyond painless destruction of the fish. Internal bacterial infections are extremely common among these fish, and only reliably treated with antibiotics. In the UK, these have to be obtained from a vet, and the so-called "anti-internal bacteria" treatments sold in fish shops in the UK are, frankly, useless. Never once heard of a fish cured of anything by using them. Antibiotics used properly (i.e., as per your vet's instructions) will be perfectly safe with your Gourami.
Internal bacterial infections often caused abdominal swelling followed by distinctive raising of the scales along the flank, so that viewed from above the fish looks like a pine cone. At that stage a cure is unlikely and again, painless destruction is the only humane option.

Constipation is a problem with Gouramis since most are partially herbivorous in the wild, and careless aquarists often forget this essential fact. If squashed tinned (or cooked) peas aren't accepted, then Daphnia may be, and these are almost as good. Obviously Gouramis are slow feeders, and if there are tetras or barbs in there, the Daphnia will be eaten long before the Gourami gets a therapeutic "dose", so you'll have to work around that using a hospital tank of some sort. If the Gourami is healthy-looking apart from the swollen abdomen, then constipation may be the issue. Adding Epsom salt at 1 to 3 teaspoons per 5 gallons can help with constipation alongside the high-fibre foods, but remember to stop adding Epsom salt once the fish is better.
Hope this helps, Neale.>
