I have had my boy Pong in a quarantine tank for over 2+ months now. Originally he began with little tumors on his tail 2 and a half years ago when he was young. I never knew what they were but they would pop off and he would heal, then they would come back again. As he got older they became more aggressive and his health declined with it. Pong is a pearl scale so it was hard to tell if his body was swollen or it was his natural body. I noticed his scales are now filling with fluids and will pop every few days. Sometimes he has 3-4 scales full of fluids at a time. He was swimming okay but now he is upside down half the day and in a corner. His tail is pretty much shredded at this point. I know this all sounds so awful and I know I should have put him down a long time ago but I love him so much. Is there anything I can possibly try, any last measure to help save pong? He still have a good appetite.
