The crab is just a bit shocked because of the move and soon he will be climbing and digging everywhere to check it out. It is best to get new crabs as soon as you get the first so that way the first crab can't find all the good spots before the others and dominate them. In a well-suited ten gallon tank, up to five medium sized crabs can live happily together. The bowls for water should be in the front corner of the tank next to each other and the food bowl should be at the opposite end of the front corner.
