This guy I met at an lfs said he puts his new fish in a saltwater solution for about an hour before he puts them in his tank. he said any illnesses are killed off, and if the fish died, then it was weak anyways. has anyone done this, or know of any way to quickly kill off anything sticking to the fish? I've had some trouble with new fish contaminating my tank, even if they and the tank they were in look well when I buy them. I really don't want to have a quarantine tank if I can help it.
