So, I have the small (5-6") spotted grouper that I recieved for free about a month ago. The orriginal owners of this fish have had it for about 2 years in a 40gal bowfront tank with so much liverock that there was barely room for the fish.
Anyway, he seems to me missing scales on his head, this was like this when I got the fish & they said that it's from him rubbing on the rocks all the time.
Before I introduced it to my own tank (55 which had just been upgraded to a 125) I quarantined him, treated him with pimafix & did a freshwater dip as a precaution, I introduced him to the tank after this was done & he seems pretty content. He eats well, is active & aside from the skin rub areas appears very healthy and alert.
I was just curious if anyone might know what it is. I have seen hole-in-head, but this doesn't look like pits at all, it's just smooth as though the scales are rubbed off. The previous owners said it's been like that for about a year.
Do you think with good care (their tank was pretty filthy) the scales & coloration might come back?
