He's nibbling at the brown algae I let grow onto my QT. I have seen him nibble a little bit on some garlic and vitachem soaked algae. I just got him yesterday and he hasn't been in QT for even 24 hrs yet, and that's usually how long it takes the fish I've had to really start eating. In my tank he looks a little thin, but not too bad, don't worry I spoil my fish in QT, he'll be fat in no time!
I'm just concerned about that darn white spot on his tail fin. I don't know if I should treat him or not. My temp is 82 and I'm feeding garlic. The lfs ( a good one) I got him from said they run a little bit of copper in their systems and treat any diseases/parasites quickly, and it shows. He did however, have this spot when I bought him, so I don't know what to think. I just want to pull it off!
