a gall crab? I got a new acan colony in today and pulled this one out after the dip, it died. I put the colony in the tank and was looking as it about 30 minutes later and notice a smaller one. They both had holes inbetween acan polyps. I pulled them out with the tip of a knife.
Anyhow any risk there is more, or will spread. Do they harm the coral or just live in it, and are they gall crabs?
