Mystery Crab

Hi Folks,
I ordered a cleaning crew online, and got a couple extra hermit crabs with it. The website I ordered it from could not tell me what they are. They seem to be quite aggressive. They constantly fight with one another and have already killed 2 cerith snails and jacked their shells despite extra shells being available. I have no coral yet, but am wondering if these guys are reef safe.

Thanks!

Hermit crabs, and a lot of other crabs, are snail killers. Its just what they do and why a few of us dont like to keep them in our tanks. They are a good part of your CUC but you have to weigh the pro's and the con's For me murdering my snails isnt worth it. Plus they scare me.

As far as an ID, it's a thin striped hermit ReefCleaners.org | Clean Up Crews and Macro Algae - Thin Striped Hermit*

I've been considering taking crabs out, but they are fun to watch.

I took all the crabs out of my tank. I hate the little bastards.
