Where julie may be the lucky exception to keeping this type of wrasse, many who have had them will say they wish they had skipped and avoided the hassle. Dragon wrasses get up to 12" long, and are very tough fish. They are also called rock-mover wrasses, and for a good reason. They are notorious for flipping over LARGE pieces of rock and rubble, as well as corals. Juveniles may be appropriate for the community tank, but will become very aggressive as they mature. Will eat small fishes, ornamental crustaceans, and many other motile invertebrates, such as snails, serpent stars, bristleworms, and mantis shrimp. Also, even large individuals have been known to jump from an open tank. HTH
