Anyone have any idea what this Bump could be on my fish? Parameters of my water are always basically perfect. I take well care of them, but when I got him, he seemed to have this. Doesn’t have any issues, isn’t scared and eats and stuff. Any ideas?
It could be a cyst? I had a goldfish with similar bumps, I wound up lancing them to get all the stuff out.
I would keep an eye on it. If it eventually bursts, treat with hydrogen peroxide swabs and frequent water changes. If it starts growing, it may be a tumor. In that case, you can’t really do anything except call a vet and get it removed. Good luck, let’s hope it isn’t something serious!
