General Description
Katherine's wrasse, scientifically known as Cirrhilabrus katherinae, belongs to the Labridae family. Wrasses are commonly found in reef aquariums due to their attractive appearances and their ability to combat unwanted invertebrates like flatworms and pyramid snails. These fish have diverse diets, ranging from zooplankton to large crustaceans and sea urchins.
Aquarium Suitability
Katherine's wrasse is generally suitable for most aquariums, but caution should be exercised as they can be aggressive towards similar species or in cramped settings. They function best as pairs, with one male and one female, or one male with multiple females. Adequate space is crucial, and a tank size of at least 300 liters is recommended.
Demands, Care, and Hardiness
This species is considered average in terms of hardiness and are known to be shy and docile. Care should be taken when housing them with more aggressive fish. They require frequent feeding, especially when newly introduced, and a varied diet to maintain their vibrant colors. Additionally, they are sensitive during transportation and acclimatization.
Reef Suitability
Katherine's wrasse is reef-compatible and typically safe to keep in reef aquariums. They play a beneficial role in reef ecosystems by controlling populations of certain invertebrates.
Aquarium Setup
Ideal for larger tanks of at least 300 liters, Katherine's wrasse thrives in environments with ample swimming space and good hiding spots among live rocks. Dimming the light initially and gradually increasing it helps acclimatize them effectively.
Behaviour
These wrasses can be aggressive towards each other, especially males, but fare well in groups with one male and multiple females. They exhibit color variations based on gender and origin, with males displaying color changes during courtship. They also practice unique sleeping habits, cocooning themselves in mucus between rocks.
Feeding and Diet
Their diet consists mainly of frozen and flake foods of appropriate sizes, supplemented with small crustaceans like krill, mysis, and artemia, as well as zooplankton such as cyclops and pods. Feeding should occur at least twice daily to support their active lifestyle.
Dimorphism and Captive Reproduction
Katherine's wrasse is hermaphroditic, capable of changing gender from male to female and vice versa. Captive reproduction may involve color changes during courtship rituals and possible egg laying by females.
Habitat and Distribution
Found in the Western Pacific, specifically in locations like Miyake-jima, Izu Islands, Japan, Guam, and the Mariana Islands, Katherine's wrasse inhabits coral reefs and enjoys a diet rich in various marine organisms.
