Common name: Nebulous wrasse
General information
The Nebulous Wrasse, Halichoeres nebulosus, is a colorful and active fish that adds both beauty and dynamism to a saltwater aquarium. It is known for its striking coloration, which can vary significantly as the fish matures. Juveniles typically display a mottled pattern of browns and whites, which transitions into a more vibrant green or blue with yellow spots in adults.
This species is part of the Labridae family, which is known for its members' cleaning behaviors, often picking off parasites from other fish. The Nebulous Wrasse is no exception and may exhibit this beneficial behavior in a community tank setting.

Care
Nebulous Wrasses are hardy and adaptable, making them suitable for both novice and experienced aquarists. They require a well-established tank with plenty of live rock for hiding and foraging. A sandy substrate is also important as these wrasses may bury themselves in the sand when they feel threatened or during the night.
They are carnivorous and thrive on a varied diet that includes frozen and live meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. It's important to feed them small amounts several times a day for optimal health.
Reproduction
In the wild, Halichoeres nebulosus is a protogynous hermaphrodite, meaning individuals start life as females and can change to males as they mature. In the aquarium, breeding these wrasses can be challenging, and there is limited information on successful captive breeding.
Habitat
The Nebulous Wrasse is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are typically seen in shallow, coral-rich areas and lagoons, often at depths of 1 to 20 meters. They are a benthic species, meaning they spend most of their time near the bottom of the reef.
Their natural habitat includes a variety of microhabitats, such as rubble, sand, and coral outcrops, which provide both food and shelter from predators.
