Well when I got him a few months ago he was beautiful in color. Now he is completely black and scoots along the bottom of the tank as if hes lazy..I treated the tank with life guard and he seems to be doing better but still fights with the other blue every time I remove the divider... these guys are small and have alot of tank room to grow into so what can I do to help this guy out.. he does seem stressed out ALOT... any suggestions would be appreciated!
