Are acro crabs bad?

[mmotown]

I bought a couple of acro colonies from live aquaria and they came with small little brown acro crabs. Not hairy but a smooth brownish tan color. Are they bad for the coral?

 

[Znut Reefer]

Those sound like the good ones. The bad ones are usually hairy and have blue eyes and a black claw. HTH.

 

[DaddyJax]

Good ones have a black mask across the eyes.

So what about the hairy ones?

I know I have one of those in one of my colonies.

I have one of these crabs in a Acro colony I got from LA
