Almost everyone on this site recommends raising the temp to around 86 F and doing extra gravel vacs to rid ich.bryangar said:I wouldn’t. Raising the temperature really does nothing if you aren’t treating the tank. All it does is speed up the ich life cycle. Raising it also lowers the oxygen in the water so you’ll have to add a lot of aeration. It’ll probably die at 96F but so will everything in the tank.
Don’t medicate the tank until you are sure it is ich. If it is ich, I have heard good things about Kordon Ich attack and Rid ich plus. I’d leave the snail in there because it’s possible ich attached to him. I’m not sure if it’s invertebrate safe. Check it out but just to be safe to add him to another tank.
