Re: WTB Acropora Crabs
Had an acro crab...lost the colony it was living in to red bugs.
After he tried to relocate to another colony...my wrasse at him.
He didn't seem to do much as far as protecting the colony from red bugs, but he did remove/eat detritus that settled at the base of the colony where he hung out.
They're pretty entertaining, but I don't think they patrol a colony like a wrasse searching for food...mine was usually in 1 or 2 spots on the colony and rarely budged.
