Hydnophora spp Green - Horn Coral - Australie

The Hydnophora  is a SPS coral often referred to as Knob, Velvet Horn, or Branch Coral. It is often confused with Acropora Coral because of its similar appearance, but they are only distantly related. Its genus name, Hydnophora, comes from the Latin hydnon (tuber) and phero (to carry), which describes its tuberous skeletal base. While members of its genus come in many shapes and colors, it is a branching variety of a cream or bright, fluorescent green color, and very short blunt polyps.

Its behavior is often labeled very aggressive; it will kill most other corals that come in close proximity with it. It is important to provide plenty of room between itself and other corals. The Hydnophora Horn Coral is a difficult coral to maintain, but if given the proper conditions, it will do well in the reef aquarium. It will require a high light level combined with a medium water movement. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water.

It will feed on micro-plankton or food designed for filter feeding invertebrates, if it is offered.
