Care Guidelines: The Melanurus Wrasse thrives in well-established aquariums with ample live rock, providing both hiding spots and foraging opportunities. A tank of at least 50 gallons is recommended to accommodate their active swimming behavior. They are known jumpers, so a tightly fitting canopy is essential to prevent escape. Additionally, a sandy substrate of at least three inches is beneficial, as they burrow themselves for sleep or to hide from perceived danger.

Diet: As carnivores, their diet should include vitamin-enriched frozen mysis shrimp, brine shrimp, and other meaty foods, along with high-quality marine flake and pellet food. Feeding them multiple times daily will ensure optimal health and coloration. They also feed on pests like bristle worms and flatworms, providing natural pest control in the aquarium.

Compatibility: Known for their peaceful nature, Melanurus Wrasses are suitable for both fish-only and reef aquariums. They coexist well with other non-aggressive species. However, they may exhibit territorial behavior towards conspecifics or similar-looking species, especially in smaller tanks. It's advisable to keep only one male per tank unless it's large enough to accommodate multiple territories. Caution is advised when housing them with invertebrates, as they may prey on smaller crustaceans.

Special Considerations: These wrasses are protogynous hermaphrodites, meaning individuals can change sex from female to male under certain conditions. Regular monitoring and maintaining stable water conditions are crucial to prevent stress-related diseases. Their burrowing behavior necessitates a suitable sandy substrate to facilitate their natural habits.

By adhering to these care guidelines, the Melanurus Wrasse can be a stunning and beneficial addition to your marine aquarium, offering both aesthetic appeal and natural pest control.
