ok i at first my cool baby star was great and now well he eats at least three full coctail size shrimp a week. the only problem anyone have problem with these once they get 3 inch across because mine now has knocked out a huge turbo snail, three nass snails, porcelian and aneaome crab. now at first i didnt reconize and missed feeding him one week and got of his feeding schedule and i let the turbo and nass snail go. but i think i will be trading him in before he starts going after fish next. anyone else have this problem i was told it was reef safe???
