These habitats are analogous to the fields of diverse species of Alcyonacean soft corals found in the western Pacific. Unlike some corals, this food may be on the microscopic level. Most are found in shallow coastal waters down to depths of 985 feet (300 m), with only a few living in deeper seas. This the result of this process is called coral bleaching, and can increase the risk of losing the entire colony.

The Bushy Sea Rod is a more aquarium friendly gorgonian that should be housed in a tank that is at least 100 gallons.

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).
