Care
Mandibular Blennies are relatively easy to care for, provided their dietary needs are met. They thrive in well-established aquariums with plenty of live rock and algae growth. It is important to ensure that there is a continuous supply of algae or supplemental foods like algae sheets or prepared herbivore diets to keep them healthy and active.
Reproduction
In the home aquarium, breeding Mandibular Blennies can be a challenge. They are not commonly bred in captivity, and little is known about their reproductive habits in the home aquarium setting.
Habitat
The natural habitat of the Mandibular Blenny includes shallow reefs and lagoons where they can be found perching on rocks or coral heads. They are adept at finding small crevices and holes to hide in when they feel threatened. Their distribution ranges across the Indo-Pacific region.
