Moonlight Gouramis

[LongS]

My girlfriend has just bought one moonlight and one Indian (banded) gourami. They Indian seems to be very healthy but the moonlight seems to have trouble getting to the bottom of the tank. When it tries to swim down to the bottom it swims in a kind of juddering motion like it has floats attatched to it preventing it from gracefully swimming.

He also looks a little bit bloated.

I noticed in the shop before buying and told the lad not to give me that one but i think he picked it up when i wasn't looking.

Is this normal?

If not what can i do to prevent death?

Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

Feed some shelled peas.
Cook peas for a few minutes, let cool down and pop out of shell.
Chop or mush the peas into small pieces and add to the tank.

It sounds like swim bladder.
Causes of swim bladder are to many dried foods, constipation, bad water quality, internal parasites, bacterial infection of the swim bladder, injury, deformed swim bladder, unstable temp.

Feed the fish frozen foods like daphnia, brime shrimp, green veg.
Frreze dried foods can also lead to swim bladder if there overfed.

Also make sure he's not resting on his side.
Looking pale or darker in colour.
Acting listless and lethagic.

He seems to be swimming about as if nothing is bothering him, he just looks bloated and looks like he is having trouble swimming to the bottom. He doesn't seem to be going off his food, or laying on his side. Just looks less stable in the water than the other fish (noticable in the shop before purchase like i said)

Girlfriend fed some peas when she first got him and doesn't seem to have done much. Is there a specific treatment for swimbladder i could get from the shop? I was tempted to try and treat the tank with an internal bacterial med. I am pretty sure it must be swimbladder though.
