I have a bubble coral not doing well. It just will not swell up. It has retracted in one half of it's skeleton. I have a dragon sand sifting goby dumping sand all of the corals and bubble. Most pictures of the bubbles I see in this website have been placed on the sand. Should I pick him up and put him on a ledge? I have a 90gal reef with sump and Metal Halide lights. I feel the substrate the goby is dumping on him is the problem. Any ideas? :thinking:
