Can i house a crayfish with a crab?

[Bryan M]

Hello i want to know if i can house a crayfish (brown lobster pet store calls it) with a red crab (dont know what hte name is but about the same size as the crayfish).

Would they fight? if they can be housed would by 60 gallon be big enough to give them there own space?

No. The crayfish requires freshwater and the red claw crab requires brackish water.
