Hi, this is my little guy Squish. I’ve had him since October 2019 with little to no health problems along the way. He is in a heated &filtered 5-gallon tank with places to hide and silk plants throughout. About 3 days ago I noticed he may have been starting to show signs of swim bladder disease and/or dropsy. I started treating the water with bettafix (today will be day 3 of treatment) and I fasted him the past 2 days (I did give him a pea yesterday and he ate a little more than half). I have inserted pictures below, as you can see his belly appears bloated on both sides and his scales may be starting to pinecone, although I can’t tell if they’re just sticking out slightly because of the bloat. I know my guy is getting old, but I can’t bear the thought of losing him so I thought I’d reach out for help. Thanks in advance.
