Mine sits under a ledge all day looking cool, I am lucky he picked a spot I can see him otherwise I guess he would be pretty boring. I bought mine from a fellow reefer who had him well trained to come up and eat, he had lost most of his fish to some parasite in his tank but the beta lived, they are very hardy. I have small fish and shrimp in the tank and he doesn't bother them at all, he is not aggressive but no one bothers him either.
