I was fishing today and and caught 2 nice crayfish. I have them in a 2 gallon plastic aquarium thinger (used to have anoles in it). Anyway i found a little white worm on the bigger one by his claw that looks like a white leech. I wanted to put them into my 55gal, but figured id quarentiene them before i do. anyway to get rid of these things w/o killing the crays?
