Although most are not accustomed to the very strong lights produced by metal halide, it is said that they will eventually adjust and grow faster because of it. Photosynthetic Gorgonians (like the Encrusting Gorgonian) can similarly be fed brine shrimp, micro-plankton, and rotifers, but this should be done weekly, as the species can survive well enough on light, a healthy water flow, and organic matter (like that of nearby-residing fish).

They are a large group of corals with a wide variety of photosynthetic and non-photosynthetic species, and are typically found in tropical and subtropical environments.
