Crab Attack...

Ok I picked this Frag up today. I am not 100% sure what it is but I do know this. My Emerald Crab is having a field day with it. He doesn't bother any other corals in my tank. This is something new. He keeps picking at it and eating it. I moved it to see if that would help Any suggestions? Here are some pics tried to get a clear one but having trouble gettting a clear pic of it.. Thanks everyone.

 

There may be dead flesh it is removing or detritus and algae also. Good move to change the location it should give the coral time to acclimate. Just keep watch on it.

 

Thanks 2in10. I will keep en eye on it. Its on one of the ceramic things. Hopefully he won't find it again. Shame I really like this frag....

 

I wouldnt worry just yet, I have seen and many others have reported their crabs just cleaning coral. but you do need to keep an eye on it cause crabs will be crab sometimes.

 

Yah he didn't look like he was cleaning this.. He was pulling it apart..

 

its a goniopora thats retract its tentacles/heads. when its looking good i bet they look like zoanthids heads on long stems doesnt it? if so, then its goniopora or alveopora.
