ya he seems to be adapting quite well actually! hasnt bothered anything in the tank. I guess im lucky! i have sm hermits and a skunk. I keep my animals well feed. He does perch on everything....kinda keepin an eye out lol even at night or early in the morning when i wake up to turn the moonlights off for darkness, there he is the night watch! Very kool fish, hes still small i think though about 2 1/2"....
