General Description
The Cutribbon wrasse, scientifically known as Stethojulis interrupta, is a member of the Labridae family. These fish, also referred to as One-line rainbowfish or Brokeline wrasse, exhibit a stunning appearance, especially when fully colored. While young, their coloring tends to be more matte, transforming into a vibrant display as they mature.
Aquarium Suitability
The Cutribbon wrasse is not the most straightforward species to keep in an aquarium and demands experienced care due to its specific requirements. When housed with more aggressive tank mates, their acclimatization process can become challenging. They have a tendency to jump out of open aquariums, necessitating secure enclosures. Additionally, these fish constantly need access to food in the water.
Demands, Care, and Hardiness
This species falls under the category of average hardiness and requires a well-established setup with ample space for swimming. Cutribbon wrasses are sensitive during transportation and acclimatization, emphasizing the need for cautious handling. They thrive best in environments with a significant amount of micro life, such as copepods and amphipods, to ensure a consistent food source.
Reef Suitability
Highly reef-compatible, the Cutribbon wrasse is considered reef safe and can coexist peacefully within reef setups. They need good hiding places, especially amidst live rocks within the reef environment.
Aquarium Setup
To support the well-being of Cutribbon wrasses, aquariums should have a minimum capacity of 1000 liters and include a deep sandy substrate of at least 5 cm to allow the fish to dig themselves in when feeling threatened or needing rest. Providing hiding spots and a varied diet consisting of small crustaceans and zooplankton is essential for their health.
Behaviour
Commonly known to be docile and shy, these wrasses should be kept away from aggressive tank mates. They exhibit a peaceful temperament but may display aggression towards similar species, underlining the importance of careful selection of tank companions.
Feeding and Diet
Cutribbon wrasses need a varied diet, including small crustaceans like Krill, Mysis, and Artemia, as well as zooplankton such as Cyclops and pods. Regular feeding is crucial due to their constant activity level.
Dimorphism
One remarkable aspect of the Cutribbon wrasse is its hermaphroditic nature, allowing individuals to change gender from female to male as needed. This species can live as a pair if introduced simultaneously in the aquarium environment.
Habitat and Distribution
In the wild, Cutribbon wrasses are found in the Indo-West Pacific region, spanning from the Red Sea and East Africa to Papua New Guinea, with a southern limit reaching Lord Howe Island. Their natural habitat includes a diverse range of locations, from Australia and Japan to Indonesia and the Central/West Pacific.
