A few days ago, I noticed that one of my 2 year-old neon tetras had a swollen abdomen and the rest of him looks emaciate. He was still swimming around and eating so I decided to observe him for a few days. 2 days ago he developped a dark spot on the side of his abdomen, so I figured he had some kind of internal tumor. This morning, the tumor or mass was completely protruding from his side. I decided it was time to euthanize him - which I really hate doing - but while netting him the mass became completely dislodged from his body. There was no bleeding or oozing fluid, but now he has a clean whitish hole in the side of his abdomen. I inspected the mass, which is about 1/4 inch (8mm) in diameter, which is huge ocnsidering that the fish is only about an inch long. The mass has the color of pale liver and a squishy, almost mucous-like texture. I can't tell if it's an organ/part of his digestive tract gone cancerous or a seperte tumour. The little guy is in quarantine right now but I'm not sure what to do. I now it's just a tetra, but I don't like killing my fish. Can he survive this kind of trauma? If so, what can I treat the water with to prevent infection and promote healing? Should I jus euhthanize him? Any advice would be much appreciated.
