What is this poccilipora.. is it a bug..critter..i am trying my best to stop this with glue, and cutting off parts of coral that the flesh was removed.. does not seem to bother other corals,like zoas and candy-cane... i do have a yellow wrasse,and he is always on the prowl.
Wish my eyes were a little sharper..Hope it gets better as i have 5 other sps in the tank. the tank has been running now for about 9 months..loving it and know there will be ups and downs.
