You're in a difficult situation, indeed. If you really want to keep them all, medicating first may be the way to go. My concern is that cycling is hard on fish even under the best conditions. With fish that are unhealthy, you may lose them anyway as the tank goes through the cycling process to be honest. But I also hear the theory that all the fish have been exposed to whatever those platies have. You may just have to medicate first, then, and hope for the best in cycling.
