Care

Two-stripe Blennies are hardy and adaptable, making them suitable for both beginner and advanced aquarists. They require an aquarium with plenty of live rock for grazing on microalgae and for hiding. These blennies are herbivores, and their diet should include a variety of algae-based foods to maintain their health and coloration. It's important to ensure that the tank is well-sealed, as blennies are known to be skilled jumpers.

Reproduction

In the wild, Two-stripe Blennies are oviparous, with males often guarding and caring for the eggs until they hatch. Breeding them in captivity can be challenging, but with the right conditions and a mature pair, it is possible to observe their fascinating reproductive behavior.

Habitat

Ecsenius aequalis is native to the Indo-Pacific region, where it is commonly found in shallow, coral-rich environments and reef slopes. They prefer areas with strong water movement and are often seen perching on coral branches or rock outcroppings.
