The Katherine's Fairy Wrasse (Cirrhilabrus Katherine) thrives in a marine aquarium environment with ample swimming space and hiding spots. Growing up to 4 inches in size, it requires a well-established tank with stable water parameters. This species is primarily carnivorous, thriving on a diet of small crustaceans, mysis shrimp, and quality flake or pellet foods supplemented with live or frozen fare. Offering a varied diet ensures their health and vibrant coloration. As a peaceful species, it should be housed with compatible tankmates and provided with a sandy substrate to sift through. Regular water changes and diligent maintenance promote the well-being of these beautiful fish.
