I have Ich in my quarantine tank. I have 3 swordtails and an Amano Shrimp in the tank. I have been doing heat treatment for 2 weeks at 87 degrees and the ich keeps coming back. I guess I need to medicate or salt. I have never had inverts and know my meds are not safe for them. Can I just move them to my community tank since they aren't supposed to be carriers? Should I add salt? Any advice is greatly appreciated!
