Plectorhinchus albovittatus
Family: Haemulidae ยท Grunts & Sweetlips
Also known as: Two-striped Sweetlips, Giant Sweetlips, White-barred Sweetlips
The Yellow Lined Sweetlips is one of the largest species in the Plectorhinchus genus, with adults capable of reaching a formidable 35 inches in length. This massive sweetlips displays a distinctive adult pattern of bold yellow to golden horizontal lines running across a grey to brownish body, with the characteristic enlarged, fleshy lips that are a hallmark of the genus. Juveniles undergo the dramatic transformation common to sweetlips, starting with dark bodies marked by contrasting white patches that gradually evolve into the yellow-lined adult pattern over several years of growth.
In the wild, Plectorhinchus albovittatus has a broad distribution across the Indo-Pacific, from the Red Sea and East African coast through the Indian Ocean to the Western Pacific. Adults are found on coral reef slopes and lagoons, typically at depths of 5 to 25 meters, where they form small groups that shelter in caves and under overhangs during the day. Like other sweetlips, they are nocturnal foragers, venturing out after dark to hunt crustaceans, worms, and benthic invertebrates across the reef and sandy bottom.
In the aquarium, the Yellow Lined Sweetlips represents perhaps the ultimate challenge among sweetlips species. Not only does it share the notorious feeding difficulties of the genus, but its enormous adult size requires an aquarium of at least 400 gallons. The combination of extreme feeding reluctance, sensitivity to water quality, susceptibility to stress-related diseases, and massive space requirements makes this species suitable only for the most experienced and well-resourced expert aquarists.
Yellow Lined Sweetlips are carnivores feeding on crustaceans, polychaete worms, and benthic invertebrates in the wild. In captivity, weaning is extraordinarily difficult. Offer live ghost shrimp, blackworms, and enriched brine shrimp initially. Attempt a very gradual transition to frozen silversides, krill, mysis, and chopped seafood. This process may take months, and success is not guaranteed.
The Yellow Lined Sweetlips can be semi-aggressive, particularly as it grows larger. Its size means it may consume small fish and will readily eat any crustaceans or worms. Best housed with other very large, robust species in a spacious FOWLR setup. Avoid highly aggressive tankmates that may stress this sensitive species during the critical acclimation period.
Check CompatibilityYellow Lined Sweetlips have not been bred in home aquariums. They are pelagic spawners in the wild, releasing gametes into the water column. Given the extreme difficulty of even keeping this species alive in captivity and its enormous adult size, captive breeding is currently not feasible. All specimens in the trade are wild-caught.
