Generally speaking, gorgonians aren't EZ to keep. They require lots of flow to keep them free of nuisance algae. Many species are azooxanthellate, so they require feedings by the aquarist, while others can rely on light and supplemental feedings.
Too many genera/species of gorgs have the same common name, so a pic or binomial name of the critter in question will help us help you.
Bottom line is they're all pretty difficult to care for.
