The Lyretail Wrasse, also known as the Moon Wrasse, is one of the most widespread and recognizable wrasse species in the Indo-Pacific. Terminal-phase males are spectacularly colorful, displaying a vivid green body with blue and purple head markings and the distinctive crescent or lyre-shaped tail that gives the species its name. The tail features bright yellow lobes with a blue center. Initial-phase fish are more subdued with brownish-green coloration.
This is an extremely active and hardy wrasse that brings constant motion and bold color to the aquarium. It swims tirelessly throughout all levels of the tank and has an engaging, curious personality. However, its high energy level and semi-aggressive temperament mean it is best suited for larger aquariums with robust tankmates that can handle its boisterous behavior. It will readily chase and intimidate smaller, more timid fish.
The Lyretail Wrasse is one of the easiest wrasses to keep in captivity, accepting virtually any meaty food offered and adapting quickly to aquarium life. It will eat ornamental shrimp and small invertebrates, making it only conditionally reef-compatible. A secure lid is essential, as this powerful swimmer is a capable jumper. Its combination of hardiness, color, and active personality makes it a favorite among fish-only and aggressive community setups.
Lyretail Wrasses are voracious carnivores that eat virtually any meaty food. In captivity, offer frozen mysis shrimp, brine shrimp, chopped seafood, marine pellets, and flake food. They will hunt small invertebrates and ornamental shrimp. Feed two to three times daily to fuel their high activity level.
The Lyretail Wrasse is semi-aggressive and very active. It should be housed with robust tankmates that can tolerate its boisterous behavior. Will chase and intimidate smaller, timid fish. Eats ornamental shrimp and small invertebrates but generally ignores corals. Good with tangs, large angelfish, and other assertive species.
Check CompatibilityLyretail Wrasses are protogynous hermaphrodites. Males maintain territories and spawn with multiple females at dusk. Pelagic eggs are released into the water column. Despite being one of the most common wrasses, captive breeding has not been commercially achieved.
