Lyretail Wrasse

Greek Name: (Thalassoma lunare)



The Lyretail Wrasse is also known as Moon Wrasse. Young fish are blue on the lower portion of their body with a black spot in the middle of the dorsal portion and an elongated black spot on the caudal fin’s base. As the fish grows older the black blotch will turn into the shape of a yellow crescent. Their bodies will start turning green, with bright face or fin markings.

The Lyretail Wrasse is best kept in a 125-gallon or bigger aquarium, with aggressive tankmates, and plenty of rocks to hide. The fish will be aggressive and attack any new members of the group. It can be kept in conjunction with a mate when the aquarium is 150 gallons or greater. It can devour bristle worms and mantis shrimp. It is not known to feed on living corals or live plants.

A Lyretail Wrasse eating plan must comprise mysis shrimp as well as vitamin-enriched brine shrimp frozen, and other meaty meals, in addition to the highest quality seafood flake, and marine pellets.

General information on Lyretail Wrasse

The Lyretail Wrasse, as an adult is green with bright fin and facial markings. It is best to keep it in an aquarium that is large, with bigger, more combative tankmates, and plenty of rocks to use for hiding. It is territorial and will berate any new members of the group, so it should be the final fish added to the tank. It can be kept in conjunction with a partner if the tank is 150 gallons or more. It can devour bristle worms and mantis shrimp. It doesn’t consume live corals or plants.
