Care Guide

Diet

Six Line Wrasses are carnivorous and require a varied diet of high-quality meaty foods. Offer frozen mysis shrimp, brine shrimp, and small crustaceans once daily. They will also consume quality carnivore pellets and benefit from occasional live food to encourage natural hunting behavior.

Behavior

Highly active and energetic fish that constantly forage along rockwork and substrate, making them excellent pest controllers for flatworms and small unwanted invertebrates. They are semi-aggressive and can be territorial with similarly-sized wrasses or fish with comparable body shapes, but generally peaceful toward larger fish and different species.

Breeding

Breeding Six Line Wrasses in captivity is extremely rare and difficult, with no established protocols for home aquarists. They are pelagic spawners that require very large systems and specific environmental triggers unlikely to occur in standard reef tanks. Captive-bred specimens are uncommon; most available fish are wild-caught.
