Acro crabs

[Luis Figueroa]

I've heard and seen these guys online. I know they have a symbiotic relationship with sps corals but what about regular clean up crew crabs? When I got my pavona coral I had one who always stay on it but without any ill affect so should I be worried if they're on a mini colony?

you should be happy they clean the coral and eat the bugs.
