Care
Yellow-axil Wrasses are relatively hardy and can adapt to life in captivity if provided with a well-established aquarium. They require a tank with plenty of live rock for hiding and foraging. This species is known for its beneficial habit of eating pests such as bristle worms and flatworms, making it a valuable cleaner fish. A varied diet of meaty foods, including frozen mysis shrimp and brine shrimp, will keep them healthy and maintain their bright coloration.
Reproduction
In the wild, Halichoeres leucoxanthus is a protogynous hermaphrodite, meaning individuals start life as females and can change to males as they mature. In the aquarium, breeding is less common, but with a stable environment and proper care, it is possible to observe their fascinating mating rituals and courtship behavior.
Habitat
The Yellow-axil Wrasse is native to the Western Pacific, where it can be found in coral-rich areas of lagoons and outer reefs. They are typically seen at depths ranging from shallow waters to about 30 meters. In the aquarium, replicating their natural environment with a mix of sandy substrate and rocky crevices is ideal for their well-being.
