Everytime I feed him, I think those sinking food wafers are laced with LSD or catnip for blennies. he stops when I get too close to the tank if I stand back I can laugh my head off for a full 5 mins before he finishes.
Naa he doesn't trust me yet he hides when I get to close but I can almost hand feed my emerald crab (almost not sure how close I want to get those claws look like that can pinch pretty good) and my clarkii still bites me when I reach in the tank.
(he is a bit of a putz)
