General information

The Clown Coris, Coris bulbifrons, is a vibrant and active fish species that adds a splash of color and dynamism to any marine aquarium. It is known for its striking appearance, with a juvenile phase featuring bold white, black, and orange stripes that transition into a more subdued but still colorful adult form with greenish-blue hues and a distinctive bulbous growth on its forehead.

This species is endemic to the Western Pacific, where it is found in a variety of reef habitats. Due to its rarity and unique appearance, the Clown Coris is a prized addition for many aquarists.

Care

The Clown Coris is a robust and adaptable species, but it requires a spacious tank to accommodate its active swimming behavior and potential size, which can reach up to 40 centimeters in length. A well-established aquarium with plenty of live rock for hiding and grazing is essential. They are known to be jumpers, so a secure lid is also necessary to prevent escape.

Their diet should include a variety of meaty foods such as frozen mysis shrimp, brine shrimp, and quality marine pellets. It's important to note that as they grow, Clown Coris may become more aggressive and may not be suitable for tanks with smaller, more timid fish.

Reproduction

In the wild, Clown Coris are protogynous hermaphrodites, meaning they are born female and can change to male later in life. Breeding in captivity is rare and challenging, requiring expert care and a large, species-specific setup to mimic their natural spawning behavior.

Habitat

Clown Coris are typically found in the coral-rich areas and sandy bottoms of the Western Pacific, from Indonesia to the Philippines, and north to Japan. They prefer depths ranging from shallow lagoons to slopes going down to about 50 meters.

Their natural habitat includes a variety of microhabitats, which they use for foraging and shelter, making them an interesting species to observe in a well-structured aquarium environment.
