Kato's Fairy Wrasse (Cirrhilabrus katoi) is a vibrant and captivating addition to any saltwater aquarium, reaching a maximum size of around 3 inches. Maintaining a varied diet consisting of high-quality frozen and live foods like mysis shrimp, brine shrimp, and enriched flakes is crucial for their health and vibrancy. They thrive in well-established reef aquariums with plenty of hiding places, moderate to high water flow, and pristine water conditions. Providing ample swimming space and a peaceful environment with compatible tank mates, such as other small, non-aggressive fish, will ensure the well-being of these beautiful wrasses.
