I've got a couple in my tanks, and they've been pretty easy for me at least. Got them in the very bottom of my tank in a low to moderate flow, just enough to keep the polyps waving in currentMy top ledge is pretty much over crowded now. Not much room for any more Acro’s. Guess I need to look lower in the tank for new ideas. Got plenty of Zoa’s. Got a hammer, Favia, some Monti’s, some Stylocoeniella and a Platygyra. The thing I don’t have and think I might like is a Torch. Are they hard to care for? The area I have left would be close to the bottom. There are areas down there where the PAR is around 200, but mostly 80-150. What are the requirement for a Torch?
