strawberry crab-experience?

Anyone here have any experience with strawberry crabs? I was tempted to buy a little guy today; fish store said they were 'non aggressive', ate algae/detritus etc..... Is this true? I'm a little nervous about crabs after our emerald crab incident (ate my mushroom, knocking over a lot of stuff, etc..)
Thank you!

 

as for crabs, i wouldnt trust anything bigger than a blue legged hermit crab in a reef tank

 

I have one in my 120 gal reef tank his shell is about 1 1/4 across and while he is avery cool color he mostly hides during the day I only see him through spaces in the rocks during the day. He is active during the evening but he is very non-aggressive and very slow moving and shy he has never knocked anything over to my knowledge. I think that emerald crabs are more of a problem when they get bigger I have a pretty large emerald and he is much more of a trouble maker. So if he is not too expensive , I would go for it but dont be surprised if you hardly ever even know he is in the tank.

If you like it they will eat it.
Whisper this like they did in the movie, "if you build it they will come."
