i was in my lfs today and saw a crocodile fish? he was around 25 bucks...i was tempted but never heard of one before. he looks sort of like a flounder and stays on the bottom. i wander if hed be good at keeping my live sand from getting algea on it. does anyone have any experience with these fish? would they get along with 2 triggers (huma,niger) in a 72 gallon tank?
