So I'm new to this site and I've been reading some other posts trying to see if they solve the answer to my question, but unfortunately they don't!
I've had my fish, Cinnamonbuddy, for 2 years now. He is a male beta fish, and he and I have become close over these two years. I bought him from Petsmart when he seemed to be very injured from fin rot.
Now, after 2 years, I have a feeling that his life is ending. About a week ago I noticed that he was floating on his side with an EXTREMELY bloated belly! I took some photos of him to petsmart and they diagnosed it as swim bladder, and told me it was nothing to be worried about. They gave me some aquarium salt to put in his tank, and told me how to treat him. I put him in an isolated tank with the salt, and after about 20 minutes in his salt bath he already started to seem better! He was more lively that I have ever had him!
But now I'm starting to get a little worried. It's been about a week since that happened and I'm already noticing him acting weird again. He used to float at the top of his tank, but now he is floating at the bottom, he won't eat, his scales look like they are starting to "pine cone", and his belly has gone from bright bright red to a very pale grey. I've been looking online to see if I can diagnose him myself with a disease, but nothing matches up properly. The closest thing I can diagnose him to is dropsy, but even that isn't making a whole bunch of sense because he is no where near bloated. Please help!
As of right now he is isolated in a gallon sized tank that is being heated to 80 degrees. I haven't fed him because he won't eat it and I don't want excess ammonia in his hospital tank. He just lays against the bowl and doesn't come up unless it's for air. PLEASE HELP!
ALSO PLEASE READ THIS: I noticed a couple of times where he would put his mouth to the gravel in his tank and his tail up. Then he just sits there. If that helps with anything!
