Moon wrasse

The Lyretail wrasse, also known as the Moon wrasse (Thalassoma lunare), is a colorful reef fish found in the Indian and Pacific Oceans. It features vibrant hues, typically with a mix of green, blue, and pink across its body and a distinct crescent or 'moon'-shaped tail, which is a standout characteristic. Adult males are especially colorful. This species is known for its active behavior and can grow up to 20 cm in length. While it is recognized in the aquarium hobby, its care requires understanding of its needs including a spacious tank with a variety of live rock formations for hiding and hunting, making it suitable for intermediate to advanced hobbyists.
