I bough 1 male guppy with my 3 females. All the males in the tank had ripped fins, I associated it with being all males and them being aggressive with each other.. Anyways, now he isn't using the fin on his left side, it looks like it's dissolved away, and his tail isnt healing. I'm assuming its fin rot. There's a bad picture below.... how does one treat fin rot?
I know its a bad picture. I'll try and describe it.
His fin seems to have disolved and that side of his body has turned sort of pink and swollen. I've never heard of anything like it.
These fish are just making me angry with how sick they are. I feel bad that I don't know how to help them, and that I may be putting my other fish at risk by keeping them together. I think I'll set up my nursery as a hospital for the time being
