The Horn Coral prefers a high light level combined with a strong, alternating water current within the aquarium. For continued good health, it will require the addition of supplemental calcium, strontium, and other trace elements to the water.
The symbiotic algae, which is called zooxanthellae, are hosted within its body, allowing it to receive the majority of its nutritional requirements from photosynthesis. While it does not require additional food to maintain its health in the reef aquarium, it will feed on micro-plankton or foods designed for filter feeding invertebrates.
Here ya go... Not my writing though, took it from another site ;) .
Good luck
 
xrayman,
It is sooooo refreshing to see a reefer asking questions and doing research BEFORE the purchase:)
Good for you. And good luck.

The "Horn Coral" is also known as the Hydnophora. Most likely this coral you're talking about is Hydophora Rigida. From my experience, it's been quite a hardy coral, and a fast grower at that. I got a small frag of Hydnophora back in August, the size of a pencil eraser. Since then, it's grown about 2-3"
I personally wouldn't keep it under anything but Metal Halides. Mine hasn't showed much growth at all under Power Compacts or VHO's, and the coloration was very weak. They do best under metal halides, and in a mature tank. In my opinion, and only in my opinion, this coral should be added to an aquarium which is 7 months or older.
FWIW,
This is a small polyp scleractinian, which will need a stable calcium level, preferably of around 400-500ppm, as the coral is calcium carbonate based.
Good Luck,
Graham

From my personal experience, it's been a very hardy coral. Again, it seems to do best in a mature tank with metal halides.
It would help if you gave us all some specs on your tank. I could give you a much more accurate answer.
