Care

Meiacanthus abditus is a hardy species that adapts well to life in captivity. They require an aquarium with plenty of rockwork and hiding places to feel secure. A stable environment with consistent water quality is essential for their well-being. They are omnivores and will accept a variety of foods including frozen and live fare, as well as high-quality marine flake and pellet foods.

Reproduction

In the wild, Meiacanthus abditus are oviparous, with females laying eggs that are then fertilized by the male. In the aquarium, breeding these fish can be a challenge, but it is possible under the right conditions. The eggs are adhesive and will be attached to the substrate or decor within the tank.

Habitat

The Hiding Blenny is native to the Western Pacific Ocean. It is typically found in shallow, coastal waters, often hiding among rubble or coral branches. They are adept at blending into their surroundings, which helps them avoid predators and capture prey.
