Care
Midnight Blennies are hardy and adaptable, making them suitable for both beginner and experienced hobbyists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These blennies are herbivores, primarily feeding on algae. Providing a varied diet that includes quality marine algae and algae-based foods will help maintain their health and coloration.
Reproduction
In the home aquarium, breeding Midnight Blennies can be a challenge. They are oviparous, with males often establishing territories and courting females by performing elaborate displays. If successful, the female will lay eggs in a secure location, which the male then guards and tends to until they hatch.
Habitat
Ecsenius melarchus is native to the Indo-Pacific region. It is commonly found in shallow, coral-rich environments and often seen darting among the crevices and overhangs of the reef. These blennies prefer areas with strong water movement and ample natural food sources.
