Just so you don't have to look it up yourself, this is from LiveAquaria.com (a go-to site if there ever was one):
Care Level: Expert Only
(Organisms in the "Expert Only" category are very difficult to maintain in captivity in the long term. The requirements of many of these corals and invertebrates are specialized, and may need to be kept in a species-specific aquarium. These species are best kept by the most advanced hobbyists and research institutions. A well-established reef aquarium is a must for these species.)
Reef Compatible: With Caution
(High:Most of the corals and invertebrates in this category originate from the shallow, pristine waters of the coral reef. They demand intense lighting along with good water flow and low nutrient levels. Because of these requirements, the Care Level for most of these corals will be "Difficult" to maintain. However, given the right conditions, they can be the fastest growing, most colorful corals in the aquarium.
Provide a lighting intensity of 4-8 watts per gallon using a combination of Metal Halides or HQI's, along with Compact Fluorescent Lighting, VHO
or T-5 Fluorescents. The spectrum of the Metal Halides will depend greatly on personal preference, but should be between 6,500°K
(reddish yellow) and 14,000°K
(blue/white). Use actinic bulbs for the supplementary fluorescent light fixture in a ratio of 1/3 to1/2 of the total wattage of the system. These actinic fluorescent bulbs can then be set on a timer to simulate both dusk and dawn on the reef.
Please Note: The lighting systems recommended for light-loving corals and invertebrates that fall under the "High" light category, produce a large amount of heat. Cooling fans and possibly a water chiller is a necessity when using these lighting systems.)
