rabs and Lobsters

[Josh]

I have a 10 gallon with a little Blue Lobster 3'' or so and i have another 10 with 3 crabs a red claw crab and 2 fiddler crabs all are about and 1'' to an 1 1\2'' i would like to bring it down to 1 if possible cause i also have a 30 gallon and am going to be setting up a 55 gallon soon, so how well or not well will they get along...

I personally wouldn't risk it, crayfish are species tank only as far as I'm concerned. I think you would be risking your pets putting them together.

the lobster will kill your crab. plus putting 3 crabs in a ten gallon is already overstocked as crabs need space and hiding places. you'd be better off with two crabs/ ten gallon and putting the lobster somewhere else.

You'd be running a risk even having 2 Blue Crayfish in a 10 gallon tank together, so I'd be reluctant to put other species with it either. I'm not sure about the cray hurting the crabs, but when the cray moults, he can be pretty vulnerable himself.
