Injury?

[thupp11]

I have a rainbow fish with what appears to be an injury at the base of his tail. What do you guys think? Medicatuons/cures?

That doesn't look very serious. Probably just an abrasion. Clean water & good nutrition should clear it up. Might dose Melafix for a disinfectant.

Thanks V, that was kinda my thought as well. Doesn't look distressed just does not swim around as he usually would with the others.
