What species do you have?
Madkins007 said:The idea behind the crabs is that they need about the same habitat and diet that the Red-foots do and they eat the wastes as well. If you are thinking about this, the guidelines I would recommend would be:
1. Have a big habitat- crowding will probably contribute to interspecies problems.
2. Figure 'big torts, small crabs' to further reduce conflict.
3. Make sure there are places the crabs can go for sleeping (they are nocturnal and should be allowed to sleep in peace.) This can be in a thick planting, box with a small hole, etc.
My torts occasionally gnaw on the crab's shells, so toss a few empties in as well- both for the torts to chew and the crabs to take over.
As for exposed, shell-less crabs- see point 3. They know they are vulnerable and will try to hide as much as they can.
I occasionally toss some pellets in the crab shelter area to make sure they have enough- but they don't need pellets any more than torts do.
