Okay was wondering about how much land would a red clawed crab need? They need at-least 1 square foot of space.
And do they sleep in the water or land or both? I am pretty sure they sleep in the water.
Here's some other info. They will dig into the substrate a lot, temp. from 72-82, they are very active at night IMO they will try to get out so be very careful!, they will eat most vege's, most of the time dead fish, and occasionally pices of driftwood! GOOD LUCK!
