I had a really nice and big Acropora that unfortunatly fell into a big BTA and croaked. I was able to save a few frags from it but there is a tiny crab still living in it that came in as a hitchhiker. The only other Acro colony that is big enough for him to play in also has another crab in it. Can two of these crabs live in one Acro??? Or can the crab just live in the rocks?? Are they host specific??? Any help is appreciated.
