Care
Caring for Blackline Fangblennies requires attention to their specific needs. They thrive in well-established aquariums with plenty of live rock for hiding and grazing on microalgae. These fish are generally peaceful but can be territorial towards their own kind, so it's best to keep them singly unless the tank is large enough to support multiple territories. They are omnivores, and their diet should include a variety of foods such as marine flakes, frozen or live brine shrimp, mysis shrimp, and algae-based foods to maintain their health and coloration.
Reproduction
In the wild, Blackline Fangblennies are oviparous, with females laying eggs that are then fertilized by the male. In the aquarium, breeding these fish can be challenging, but it is possible with a well-maintained environment and careful monitoring. The eggs are adhesive and will be attached to the substrate or decor within the tank. Once hatched, the larvae will require small, nutritious food sources like rotifers or copepods.
Habitat
Meiacanthus phaeus is found in the Western Pacific, particularly around the Philippines and Indonesia. They inhabit shallow reefs and lagoons, often seeking refuge among stony corals and rubble. In the aquarium, replicating their natural environment with a variety of hiding places and stable water conditions is essential for their well-being.
