Pinstriped Wrasse

Halichoeres melanurus

Habitat & Distribution:  Coral reefs, Western Indo-Pacific

Diet : Zooplankton and small invertebrates

Size: Up to 13 cm

Lifespan: 5-7 years

Description

Males have a light purple body with wavy pink-to-orange lines on their yellowish-green heads, 3–6 narrow blue stripes on the upper body, yellow pectoral fin bases, and a patch of black scales behind the pectoral fins. Females feature alternating yellowish-orange and blue stripes, a large black ocellus (eyespot) in the middle of the dorsal fin, a small black spot at the front of the dorsal fin, and a small black ocellus at the upper base of the caudal fin.

Behavior

They are active hunters that spend their days scouring the reef in search of small invertebrates, making them an excellent choice for pest control in reef aquariums. At night or when threatened, the fish will quickly dive and bury itself in the sand substrate.

Reproduction

Pinstriped Wrasse is a protogynous hermaphrodite, meaning they are all born female and have the ability to transform into males. In the wild, they live in harems typically consisting of one dominant male and several females.

Communication & Perception

Pinstriped Wrasse communicates with and perceives its environment primarily through sophisticated vision, utilizing color patterns to facilitate social structures and intraspecific interactions—visual communication being particularly crucial given its active, diurnal lifestyle in shallow, light-rich environments.

Predator

lionfish, dogfish, sharks, and barracuda
