Little crab in my monti. Ok or not so much?

Kinda hard to get a pic but he looks like he's got star trek goggles on. My clown goby keeps trying to attack him.

I don't even see it, but that's acropora.

If it looks like this:

or this:

You're good to go; those are Tetralia spp. crabs. Commensal crabs of acros.

 

[Ssteve]

I have a couple of those is some of my acro colonies. Just keep an eye on them, the shouldn't hurt the acro, but if they start, you will need to get them out.

These acro crabs never hurt the colony..
The blue eyed hairy crabs that come in the colonies sometimes do eat the coral but the smooth bodied crabs like yours are always safe..
