Tropical Rainbow Crab.

Hi I have a Tropical Rainbow Crab it was bought for me by my family who know my love for strange critters and animals in general. I have crab food and give him fish and he has a heater and water and a platform to get out of the water to eat. However I can't find any information on the net about them are they rare? I can't seem to find a book either normally I wouldn't by a pet without know every thing about them but I just came home and there he was. Does anyone know where I can find information about them and id they can be tamed petted what ever. thanks

um HELLO?!?!?!? this is the lizard forum, not a dumb crab forum! please stay in your oun pet area, because some people actually WANT to talk about lizards! THANK YOU!

I think since we don't have a crab forum then its OK :) Who says crabs are dumb anyway?
