Aggressive acro crab??

[reefhoarder]

What's up guys. So I have had a anemone crab and a peppermint shrimp in my tank for about 2 weeks now and a few days ago I bought 2 acro crabs. I did a lot of research and from what I've seen is that the acros are not aggressive like at all. (As far as I know/read).

However, I woke up this morning and saw that my anemone crab was missing a big claw and a few legs. He can still move though. Was just curious to as if the acros could have possibly done it? I am 99% sure that my peppermint wouldn't do such a thing considering he is always friendly and usually chills on the other side of the tank.

Any help??

He may have gotten to close to a colony the Trapezia was hosting. They will protect their colony from friend or foe. Mine even chase away my wrasses who could easily make a meal of him. They do have powerful claws.
