I got my Kole from j&l a few months ago and it took a few days for him to get comfortable.
Mine loves nori and gets a little aggressive if I don't put a fresh clip in there daily... Also he loves flakes, pellets and frozen which I find odd... and he constantly grazes on the film algae on the back walls and rocks.
When I clean the glass he fights with mirror image which is entertaining to watch. My favorite fish, well they are all favorite
