oh.. if you want these crayfish, you will need a sturdy cover
over the tank coz they'll climb out and try to run away
they're cool as heck..
and if you can get stuff like snails or worms, they'll catch and
eat them 
what will happen if I eat crayfish in front of them :P
oh, I think that's exactly what happened to zora's departed pet
lobster. the poor fella tried to run away or something :P
