hello. i have a 90 g tank, with a blue tang and a moorish idol. i have just got the moorish idol feeding, and he is hungrier than ever. when he was being introduced, the tang was really aggressive and at one stage tore his fin. it seemed to be growing out, but now im not so sure, as he now has about an inch of just bone, where the fin should be. the end of his skin (or what ever) is all shaby and there is a bit of black where it should be white. what is causing this? is there anything i can do?
