Eibli angel's body rotting

[LobsterOfJustice]

Hey all,

I bought this Eibli angel about a week ago, he is about 1.5". On his sides, where his pectoral fins touch his body, they body looks "worn down"... the tissue is getting thinner and turning into an open wound. It is on both sides. His fin on one side is also missing some tissue. There is no visible fungal growth or anything, its just like his skin is disappearing. He is swimming, eating, and otherwise acting completely normal. Normally I try to let fish get through things on their own but it has been a week and has definantly become worse.

I have a 15g quarrantine tank I can set up, as long as I can catch him, but I'm not sure what to treat with once I get him in there. I tried to get a picture, but he is too small and quick.

Thanks,
Mike

It sounds like fin rot a bacterial infection. Treat with antibiotics for seven days. If you can't QT him try melafix in the display. This is a natural antibiotic. Shut simmer down during treatment. Remove carbon if your using it. Once treatment is finished do 25% water change.
