Got myself a 20 gallon high tank that is setup. Other than some Anthelias I am looking for some very basic starter corals with little care needed. For now I am using a 15W Flourescent 50/50 Actinic bulb. So the amount of light needs to be very low light. My lfs and my research has recommended leathers, anthelias, zoas. What do you think? are their any others for my setup?
