So I’ve recently moved back into my parents house where my avid lives. He’s not well. He has two growths on his back, his tail is very red and now he’s getting extremely bloated and not pooping or eating. Ive purchased an ammonia alert that sits in the tank and says ammonia is fine. I’ve checked the ph which was a little high but I’ve managed to reduce that to safe levels. I really don’t know what to do to help him. I’ve been doing regular partial water changes and I’ve been using API stress coat for the water. Please any advice would be greatly appreciated.
