Hey guys. I'm faced with a difficult decision here. I have a fish in my 45g that is very old and has a crooked spine and abrasions on its side. He's some type of tetra I was given a few years ago. These are symptoms of fish TB, and I don't want it to spread. Should I euthanize this guy before the condition spreads to other fish, or will the others be ok if I let whatever's ailing him take its course? He seems to be acting fine, but he's just crooked and has some abrasions.
Thanks.
Thanks.
