Red Clawed Crab Help

[hermitcrabsrawesome]

I am planning on purchasing 3 Red Clawed Crabs from Petsmart, but no matter how much i search I can not find any information on them exept that they require brackish water with a salinity of 1.005,and they need room to climb. Any information on them will help me alot.

I can't remember the website or I would link you, but someone kept red clawed and fiddler crabs and learned that both in the same tank was a bad idea--the red clawed went after the fiddlers--and that both species of crab liked the burrow in the substrate, so sand/dirt/coconut husk. They had it set up as a beach because apparently while they like to climb, they can't do it very well, and if they couldn't reach the land, they drowned. Apparently, they got on ok with his mudskippers, though.
