hi, quick question. i've read that all euphyillas can touch one another without any worries about aggression. I've also read that this only applies with frogspawn and hammer corals, but not with torch coral. so which is true? the reason i ask is that i have had all three specimens in my set up together for one year now and although i have the frogspawn and hammer coral within touching range, as a precaution i have kept the torch at a distance. now i plan to rearrange my tank and i would like to keep my torch closer to the others. can i/should i do this? also, relative to the other two, my torch is fairly slow growing. do they need more light/nutrients than the other two, or are they simply more delicate? i have a 72 bow lit by 4*54w T5's. the tank is 22 in. deep and i have all three are roughly 18 to 14 inches from the surface, with the hammer being lowest and the frogspawn highest. both have shown fast and extensive growth, but the torch has grown very slowly. thanks for any help. sorry for the long post
