Not sure what to think: my black neon tetra is bloated and swimming eraticly away from the school. when he stops flapping his fins he floats to the top up side down!

Try feeding the tank peas. It sometimes helps by giving the fish gas, and they get over being full of air.

For neons, the peas will, of course, have to be crumbled into tiny little pieces.

This sounds like a swim bladder problem, and peas can sometimes treat that, but swim bladder problems are often pretty serious things. If you don't have any labyrinth fish in the tank, you might also want to try some PimaFix or MelaFix (I can't remember which one is listed for internal problems, but it says on the bottle), as well.

the swim bladder thing is what I thought, but I should have said My neon was swimming eraticly around the tank, because he was dead this morning. I just wanted to know incase it happened to any of my other neons.
