Hi there. I'm Theresa from the Philippines. I need help with my FH. I think it ate something that did not agree with him. Suddenly he was swimming upside down. So i restricted his space to keep him upright. He was not eating. First I thought that he probably hit his head and was just dazed but after three days his bottom area where he excretes became swollen, red, and was decaying. So i placed some penicillin tablet which I powderized. It healed his wound. AAnd he was able to potty. But now he cant seem to keep his balance. So i still keep him contained. I have limited resources. I dont know how to check the water acidity. Please help me. I am worried for my baby fish.
