So I was at my LFS the other day and saw they had an oscar that had been baddly injured. His entire gill cover is repped off exposeing his red gills. So i decided i would take him home (for free of course) and i set him up in a little twenty gallon. Hes about an inch and dont worry he wont be in the twenty for long. He is really active now that hes alone. What i was wondering is if he'll survive and/or will his gill cover grow back? will it always be exposed?? or is death inevitable and Im just prolonging it? Just about an hour ago he ate three feeders. He swims arround fine. Just wanted some of your input.
