I was at the Florida Aquarium yesterday and was admiring their reef tank and they had very large Hammers, Torches, and Frogspawns all literally touching each other they were huge and flourishing in different sections of the tank, my question is can this be done safely? I thought that these 3 corals would all sting each other to death since these are usually all pretty aggressive corals, in my tank they are separated, all of their corals were large and very healthy so I guess it's safe but I thought that this couldn't be done
