I have them, too! But mine are kinda reddish. Nothing eats them. If I brush them off the glass with the magnet or blow them off with the turkey baster, they just swim until they get to a coral or back to the glass. I can't tell they hurt anything, but they sure do hurt the view. I don't know how to get rid of them since I can't find anything to eat them. Hope you find out soon. Let us all know. islander |
