I've found that crabs in general are pretty nasty little buggers....and that's part of the entertainment. I've got a couple golfball sized Tongan Tricolor Hermits with the rest of of various Hermits (about 20 total), really cool to watch. They push and shove at feeding time, missing out on food because they're busy holding back another crab, and the Tongans like to flick grains of sand at other crabs to make them move. I've got land hermits too, same thing, rude little jerks, but so cool.
