What Bundoon Blenny look like

The Bundoon Blenny (Meiacanthus bundoon) exhibits a streamlined body that can reach a maximum adult size of approximately 10 cm (4 inches). Its coloration is predominantly a vibrant blue with yellow accents, particularly noticeable on the dorsal and anal fins, which are elongated and filamentous, enhancing its hydrodynamic profile. Sexual dimorphism is subtle, with males typically displaying more pronounced coloration and slightly larger fins compared to females. This species possesses a unique set of venomous fangs located in the lower jaw, which serve as a defensive adaptation against predators. The presence of a lateral line system allows for enhanced sensory perception in its environment, aiding in navigation and prey detection.

Behavior & temperament

The Bundoon Blenny is a diurnal species that exhibits a semi-aggressive temperament, often establishing territories within its habitat. It is typically found in shallow reef environments, where it occupies the upper water column. Social hierarchies can develop among individuals, with dominant males displaying more vibrant coloration and engaging in displays to ward off rivals. Breeding behavior involves courtship displays, where males perform intricate movements to attract females. This species is known for its curious nature, often seen peering out from crevices and rock formations, and it exhibits a tendency to retreat into hiding when threatened.

Diet & feeding

In the wild, the Bundoon Blenny primarily feeds on small zooplankton and algae. In captivity, it requires a varied diet that includes high-quality pellets, frozen mysis shrimp, and spirulina-based foods to ensure optimal health.

Behind the name

The genus name 'Meiacanthus' is derived from Greek, where 'mei' means 'less' and 'akanthos' means 'thorn', referring to the reduced spine structure of the dorsal fin. The species name 'bundoon' is derived from local vernacular, reflecting its regional significance.
