Care

Ecsenius minutus is a hardy species that adapts well to life in captivity, provided that its environment is stable and well-maintained. They thrive in aquariums with plenty of live rock for grazing and hiding. A varied diet of small, meaty foods such as finely chopped crustaceans, mysis shrimp, and quality marine flake or pellet food will help maintain their health and coloration.

Reproduction

In the wild, blennies like Ecsenius minutus are known to be oviparous, with distinct pairing during breeding. While breeding in the home aquarium is not common, it is possible under the right conditions. The male typically guards the eggs until they hatch.

Habitat

The Minute Blenny is found in the Western Pacific, often associated with coral-rich areas and rubble slopes. They are usually observed in shallow waters, where they blend in with their surroundings to avoid predators.

Geographical distribution includes areas such as the Philippines, Indonesia, and Papua New Guinea. Their preference for shallow reef environments makes them a natural choice for aquarists seeking to replicate a biotope aquarium.
