Ring Wrasse

(Hologymnosus annulatus)

Add Hologymnosus Wrasse to well established aquariums. Provide an aquarium with ample rock work with plenty of crevices, cracks, caves and a deep sand bed. House only one Hologymnosus 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. Hologymnosus 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.
