Common name: greenband wrasse

General information

The Yellow Deepwater Wrasse, scientifically known as Halichoeres bathyphilus, is a captivating species admired for its vibrant yellow coloration and dynamic behavior. This species is part of the Labridae family, which is known for the diversity and beauty of its members. The Yellow Deepwater Wrasse is a less common sight in the aquarium trade compared to other wrasses, but it is highly sought after by enthusiasts for its unique appearance and the challenge it presents.

Care

Caring for the Yellow Deepwater Wrasse requires a well-established aquarium with a sandy substrate to allow for their natural burrowing behavior. They are active swimmers and need ample space to roam, so a larger tank is recommended. These wrasses are carnivorous and thrive on a diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Consistent water quality and stable parameters are crucial for their well-being.

Reproduction

In the wild, Halichoeres bathyphilus exhibits protogynous hermaphroditism, where individuals start life as females and can change to males as they mature. This is a common trait among wrasses. In the aquarium, breeding these fish can be challenging due to their specific requirements and the need for a large, mature group to increase the chances of successful pairing.

Habitat

The Yellow Deepwater Wrasse is typically found in deeper waters of the Western Pacific, ranging from the Philippines to northern Australia. They inhabit slopes and drop-offs where they can be seen swimming actively during the day. At night, they retreat into the sand to rest and protect themselves from predators.
