So I bought this guy at my pet store today to try and save him. I'm pretty sure he has swim bladder disease and I don't know if he has any other issues. His little container of water was filthy. I put him in a 5 gallon inside of a breeder box so that he wouldn't be floating around the whole tank. I'm trying to feed him peas but he doesn't seem interested when I get it by his mouth. It seems like he tried it to get a few at the bottom when he was in the store container but now he can't swim down to the bottom of the breeding box to get any once it sinks. I put Seachem Stress Relief in with him. I don't know what else I can do to help him. How do you cure swim bladder disease in a betta.
