I'd prolly say 70% no 30% yes. Most of the time the hammer is the aggressor and stings the torch. Hammers seem to be OK next to frogspawns and frogspawns seem to be OK next to torches for the most part, but usually hammers and torches aren't the best of friends. When mixing Euphilia genus corals I always advise to give it a shot for a couple days and keep an eye on them. If they don't play nice, seperate them. Either way, they can handle a little warfare for a few days
