Tell Me about Emerald Crabs

[boomper]

I have some bubble algae starting and I want to get some emerald crabs. How many would I need in a 29 gal ? Will they have a problem with blue and red leg hermits?

IMO 1 or 2 max. shouldnt have problems with the hermits.

I have 2 in my 30 gallon with no problems.

Hiya,
I've got two in my 37 with red hermits, turbo's, nassirua and a peppermint shrimp. No problems there. At one time I thought I had a mantis shrimp because my red's were disappearing but now I think the hermits were fighting each other for their shells. Didn't want the ones on the sand...NOOooo, had to have their tankmates.
