How hard are they to keep? What kind of lighting do you use? Are they more nitrate tolerant then other corals?. I would never keep them in my 75. Trates too high, nasty hermits and i only have 80 watts of light. Maybe on my 28g, 150 watts , 2 clowns , brittle star and anenome. What do you think. I would appreciate it if you could help me out.
