Common name: Red Sea mimic blenny
General information
Ecsenius gravieri, commonly known as Gravier's Blenny or Red Sea Mimic Blenny, is a small, colorful fish that is well-suited for reef aquariums. This species is known for its unique behavior of mimicking other blennies, particularly the Meiacanthus species, which are venomous. This mimicry serves as a defense mechanism against predators. Gravier's Blenny has a slender body with a combination of blue, yellow, and orange hues that make it a visually appealing addition to any tank.

Care
Gravier's Blenny is a hardy species that adapts well to life in captivity. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These blennies are herbivores, feeding primarily on algae. It's important to ensure a continuous supply of algae or vegetable-based foods to keep them healthy. They are peaceful fish but can be territorial towards other blennies.
Reproduction
In the wild, Ecsenius gravieri are oviparous, with males guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging due to their specific mating rituals and the need for pristine water conditions.
Habitat
Gravier's Blenny is endemic to the Red Sea. They are commonly found in shallow waters, often in and around coral reefs where they can easily blend in with their surroundings and find ample food sources.
