I have had this betta for a little over a year now. I feed him 1 piece of bloodworm or brine shrimp every day so I know he is not overfed. About a week ago I noticed he was unable to get away from the surface of the water. He still agressively attacks the food when he is fed but if it starts to sink he can’t go more then an inch down into the water. Sometimes I find him on his side as well. 2 nights ago he seemed like he was fine again since I saw him near the bottom but the following morning he was on top again and has stayed that way, still with a healthy appetite. I’m guessing he is having trouble with his swim bladder. Any ideas on how I can help him out? Please don’t say his days are over just flush him.
