When I purchased my BGK, i noticed it had a chunk bitten out of its fin. This was probably from another BGK in the over crowded tank my lfs had kept it in. When I brought it home and upon further inspeection i noticed a some whiteing areas around the injury. Fearing that it may be ich or fin rot, I placed some aquarium salt, raised the temp, and added a half-dose of medication in its tank. After a few days all the symptoms had disappeared, and it was eating and swimming actively now. However, it still had a missing chunk from its fin. I was wondering if that will ever grow back?, and if so how long?
