Bad acro crab?

[cotter4601]

I recently lost a acropora and I just thought it was something I did. The coral did have a little crab in it that I assumed was a acro crab and was beneficial to it. Recently the crab took up residence in another piece of acropora I have and now it appears to be nibbled on. Does this pic look like a hairy acro crab?

Bad crab. They've done damage to several acros I have. Tweezer him and banish him. The good acro crabs usually come in two varieties that I've seen. One is basically white with a black mask across it's face and the other is a bit bigger, and a combination of pink and blue coloring. Though I'm sure there are more acro crabs out there that don't cause any harm.

I just saw one on my SPS....I will try to catch it out tomorrow, but I haven't notice any damage on my SPS.
