I have a ghost shrimp and Nerite snail that were in a tank with a Betta that had advanced Swim Bladder disease. They have been in a quarantine tank since December 28. Can they infect other fish or shrimp if I put them back in a community tank. Is there any medication that is safe to use to make sure they will not transmit any diseases? Should I be concerned? Can I go ahead and put them in the tank with healthy fish and shrimp?
