Care
Caring for Blackeye Thicklips requires a spacious aquarium due to their size and active swimming behavior. They are generally peaceful but can be territorial with their own kind or similar-looking species. A varied diet of meaty foods, including frozen and live offerings, will keep them healthy and their colors bright.
Reproduction
In the wild, Blackeye Thicklips are egg-layers that exhibit complex breeding behaviors. However, breeding them in captivity is challenging and rarely achieved by hobbyists. Their social dynamics and spawning rituals can be fascinating to observe in larger, species-specific setups.
Habitat
Blackeye Thicklips are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer reef environments, often seen in lagoons and on outer reef slopes, where they can be found in small groups or pairs.
