My advice if you are concerned about the temp, which most of your stock will handle with little issue, is to raise it to 80-81, add salt as well as seachem paraguard or rid-ich( I've never used rid-ich so I don't know how harsh it is, but all my fish, scale-less included, handle paraguard without any stress). the raised temp will speed up the life cycle of the parasite, and the salt/med combo will knock it out in the free swimming stage. You are looking at a 7-10 day battle generally. The high temp method prevents the parasite from reproducing but again if you are concerned about the fish handling the hotter temps, I'd go the other route and just treat the tank.
