Common Names: Knob coral, velvet horn, branch coral

Difficulty Level: Hydnophora is one of the easier SPS corals with minimal chemical needs other than stability and higher light.

Feeding: Hydno will eat small particulate meat based foods such as rotifers or cyclopeze.

Lighting: Higher lighting is a must as with most SPS corals.

Waterflow: Strong random current will suite hydnophora in keeping its flesh clear of detritus and other debris.

Placement: Hydno is an aggressive SPS coral, so keep it away from other more sensitive species.

General: Hydnophora comes in many different growth forms, but with the same super-fluorescent coloration on most, they are easy to pick out.
