Yes Anthony! They are more of a curse then you would think. Unfortunately there are very nice corals growing on the same rock so no flipping over for these. My only option is to continue to cut them off.:tired:
Awilda - can you remove the other corals sharing the same rock and then trade the rock to someone who wants them? I know you don't want to give up the rocks due to their size. Trade a rock load for an empty rock?
Kat, 1 of the rocks has 3 acropora sps, and completely encrusted with the green cap. the other one has some other sps on it.
Cutting them off every so often is my only option.LOL At least they have chosen rocks that are high up. I only have to go up to my elbow to get at them.
