i have a cherub angel in my 90gal.(had to borrow this pic cause he wont stay still.)a few weeks back he started pestering my clam and i feared that i would have to get rid of him like the first one i had got from HOF.anyway i moved my clam away from the angels area and its been a week that he hasnt bothered the clam and its closer to my clowns where they live in there anthelia colony so the angels gets chased off. also i added a gold maxima and he doesnt even look its way,so im keeping my fingers crossed.
