Thanks Bronco. I'll google some sps corals.
Well, it's not corraline, because it's soft. Not as soft as a mushroom but definetly soft. Both places on either side of the crab picture are the same coral. The one at the bottom looks like it may be thicker? and it could be my imagination but seems to be rising up over the ridges now. I've also just found two more unidentified corals on this shipment of rock too! One is an area that has two quarter size brown patches. I thought is was just algae and even tried to scrub it off. Today both patches are raised up just a little with little polyps sticking out but the whole thing is brown, polyps and all. I'm going to try to position that rock in a better light location. The other one I found is on the back of the same rock and the only way I can describe is is a 4" long 1/4" wide strip of greyish/bluish coral. feels like leather or rubber underwater, but also somewhat soft. This side of the rock doesn't haven't any corraline on it, so I don't think it was getting a lot of light, whatever is was. I'll try to get pics tonight.
