Hi all,
I hope someone can help. I came home today to find one of my serpae tetras swimming head down in the tank. I've had it a little over a week and would say he's been a little more lethargic than the other one the whole time (I don't have room for a full school).
I've been reading up on the site and think it might be swim bladder disease, but I don't know if feeding him peas will work because he hasn't eaten anything at all the last few days. He swims up to look at the flakes then doesn't eat them, or spits them out again. If I give him a pea, the other one will eat it.
What should I do?

You might try Hikari freeze-dried daphnia. Fish that aren't eating will sometimes eat that and it will help his system simliar to peas if he eats it. You could also try soaking tiny pieces of pea in a little garlic juice to enhance the appeal of them.
