I just picked up about 7 small crayfish( crawdads, crawfish...) today and i really would like to know if any one has successfully quarantined them. i have read and heard a lot of things but not anything definite. they are in a 10 gallon and i want to add ghost shrimp and maybe snails so that the tank will provide a good food source for my oscars. the crayfish came from a small run off from the pond near my house. can salt be used? the anti-parasite tablets i got said they weren't safe to use on crustaceans. any advice would be helpful.
