Can you pick up fiddler out of their tank and play with them?

eeehhh.... if its going to be a pet... i wouldnt. however, i use crayfish as food for some of my fish... and every time i go to feed them to my fish, i first put it on the floor for a few minutes and let my cats play with it lol.... and crayfish are similar... but i wouldnt do it if it is a pet or at least not very often... however, they do enjoy having places to crawl on outside of the water... so it might not hurt them since they naturally do it anyway... i dunno, its up to you
