What Striped Blenny look like

The Striped Blenny (Meiacanthus grammistes) exhibits a slender, elongated body that can reach a maximum adult size of approximately 10 cm (4 inches). Its coloration is characterized by a series of striking vertical blue and yellow stripes that run along the body, providing effective camouflage among the coral reefs. The head is relatively large with a pronounced, blunt snout, and the mouth is equipped with sharp, canine-like teeth adapted for grazing on algae. Sexual dimorphism is subtle; males tend to display more vibrant coloration and slightly larger dorsal fins compared to females. Defensive adaptations include the ability to quickly retreat into crevices and the presence of venomous spines in the dorsal fin, which can deter potential predators. The lateral line system is well-developed, aiding in the detection of water movement and potential threats.

Behavior & temperament

The Striped Blenny is a diurnal species, exhibiting a predominantly solitary lifestyle with occasional social interactions during breeding periods. It is typically found at mid to upper reef levels, where it actively grazes on algae and detritus. Breeding behavior involves males establishing territories and performing courtship displays to attract females. The species is generally non-aggressive but can exhibit territoriality, particularly during the breeding season. It is known for its quick darting movements and ability to hide within rock crevices when threatened.

Diet & feeding

In the wild, the Striped Blenny primarily feeds on algae and small invertebrates, making it an omnivorous grazer. In captivity, it requires a diet rich in marine algae, spirulina, and high-quality pellets or flakes supplemented with occasional protein sources.

Behind the name

The genus name 'Meiacanthus' derives from the Greek words 'mei' meaning 'less' and 'akantha' meaning 'thorn', referring to the reduced spines of the dorsal fin. The species name 'grammistes' comes from the Greek 'gramma', meaning 'line' or 'stripe', indicative of its striped appearance.
