not really , if you mean separated than seerated then no again as the crayfish may scare the pig it would be advisable not to as the crayfish could also get its claws through bars and snap at the pig , the pig might even bite it! also crayfish can only live out of water for a few months so if i was you i'd buy a fish tank and fill it with water and put the crayfish in there!
