Blackeye Thicklip Wrasse

(Hemigymnus melapterus)

Add Hemigymnus Wrasse to well established aquariums. Provide an aquarium with ample rock work with plenty of crevices, cracks, caves and a deep sand bed. Careful planning should be taken as Hemigymnus become very large and are difficult to maintain in home aquariums. House only one Hemigymnus as they may become territorial. If frightened they may bury themselves in the sand. These Wrasse will pick up mouthfuls of sand, sift it for crustaceans and then spit out the sand. Hemigymnus Wrasse generally feed on benthic invertebrates and small fish. Provide a diet rich in meaty foods fed multiple times daily. Adults may require live foods such as Grass or Glass shrimp in order to maintain good health. Wrasse are hermaphrodites meaning they start as juveniles/females but at some point in their life may turn into a male. Wrasse are jumpers be sure to provide an aquarium with a tight fitting lid.

The Barred Thicklip Wrasse are sometimes also known as the Blackedge Thicklip or Half and Half Wrasse. Not often seen in the aquarium trade. Juveniles and adults will have color differences. Juveniles have a white colored front half and a black back half with a bit of yellow in its tail as they mature the white begins to turn green with blue and pink markings on its head and the black turns to a dark green.
