My little guy was subject to accidental melafix poisoning about 2 months ago. He was nearly dead, but I managed to cure him with BettaRevice but now I think the damage that had been done has finally caught up with him and I wanted some advice on what I should do (does he have a chance? Should I let nature take its course?)
A couple days ago I noticed some very minor pineconing and from what I've read this always means dropsy, which is almost always fatal. Since the illness I've changed his water about 4 times every week (he's in a 2.5 gallon). I also tested the water a few times. So I know the reason for his ailments are not due to poor water quality. He also has not eaten like a normal betta for the past two months, and I always take out uneaten food after a couple minutes. I've tried a lot of different things and I'm able to get him to eat about one pellet every week :( He still swims around but since I've noticed the pineconing he moves a lot less. He doesn't have any noticeable swelling, but I also read they can be so skinny you can't notice, which would make sense since he's not eating anything.
I have a theory that when he was exposed to the melafix it damaged some of his organs and they're just now starting to fail. Which to me sounds like he really doesn't have a chance... Does anyone have any other suggestions as to what is going on with him, or what I should do?
