I have a sun coral that wasnt doing we mainly because when I feed it my hermit crabs attack it and steal the food. So I made a little feeding dome for my sun coral it was doing lots better untill last night. I fed my coral with the dome and as usual the crabs attacked the dome. However this time when I took the dome off they went more crazy then normal and clawed at the sun coral so badly to get the food that the coral is now dammaged in several spots. You can see the skeleton in spots. I am at a loss as to what I should or could do about the crabs. They get lots of food. They are reef safe crabs. They are just a little crazy. Any Ideas I dont want to lood my sun coral because of my stupid crabs!
