I don't know if I should euthanize Alphie, my male Betta. I don't want to. He has had several weeks of compounding problems. He shares his tank with two Tetras. Around Christmas I attempted to introduce a Plecostomus . The Plecostomus attacked Alphie and left him with only one half of a pectoral fin. The fin has shown some regeneration. A couple of weeks ago he started floating on his side at top of tank but was still eating. Last week he was curling his body into an "S" form and was showing a sore on one of his gill flaps. Following advice from forums on this site I administered diluted doses of Melafix. For the past three days he barely seems to be hanging on. Mostly he's lying just how he's fallen at the bottom of the tank. I have stopped the Melafix doses (unsure as to whether or not I was exacerbating his condition) Until a couple of days ago I was changing the water in the 10 ga. tank at about 25% ever day. The last water change seemed to cause him a great deal of stress so I have not continued. I don't have a water diagnostic. I'm a Newbie-thing-a-ma-bob. Alfie is my first fish.
Please advise. Thank you.
