HELP! loosing acans...

[nerdz]

Still not sure whats going on...

I did just pull all my rock out tonight to catch a pest crab that has been in there 3+ years... He has grazed my SPS down, maybe Acans too?

I've tried to trap him before without success. I resisted pulling out the rocks because I didn't want my 2 RTBA to walk, (its only a 34G).

Anyone know what it is? Xanthidae Crab??? Ether way, he's now living on top of a Mag5 in the sump...
