Black-backed (China) Wrasse EXPERT ONLY

Overview

Physical Description and Identification

• Females and Juveniles: Feature a pearl-white stomach and midsection with a solid black upper half (head and back). This black area is covered in small, vibrant blue spots. They also have a blue-edged black spot on their gill cover and another at the rear of the dorsal fin.
• Males: Large adult males typically have less pronounced black on their backs, often displaying maroon and blue designs above their eyes and on their fins. They can grow up to 9 inches (23 cm) in length. 

Habitat and Diet

Aquarium Care

• Tank Requirements: They require a large tank, at least 100-120 gallons, with ample live rock for shelter and foraging. A deep sandbed (minimum 2 inches) is necessary as they burrow at night or when stressed. A secure lid is also needed to prevent them from jumping out.
• Diet in Captivity: They need to be fed a varied, meaty diet multiple times daily, including high-quality marine foods like flakes, pellets, and vitamin-enriched frozen mysis shrimp.
• Compatibility: While generally peaceful with other fish, they can become semi-aggressive towards other Black-backed Wrasses as adults, and it is usually recommended to keep only one per tank. Keep in mind they may prey on small crustaceans and ornamental shrimp.
