Spotted filefish, also known as Cantherhines dumerilii, is a unique and intriguing marine fish that belongs to the family Monacanthidae. This medium-sized filefish is found in the warm waters of the Indo-Pacific region, from the Red Sea to French Polynesia, and is known for its striking appearance and behavior.
The spotted filefish has an elongated and oval-shaped body, with a small head and a protruding mouth. Its body is covered in small spots of various colors, including white, brown, and green. Its dorsal fin is tall and triangular, while its anal fin is shorter and rounded. The coloration and pattern of the spotted filefish can vary greatly depending on its age, mood, and environment.
The spotted filefish is a curious and active fish that is known for its unique behavior. It has the ability to change its color and pattern to blend in with its surroundings, making it difficult for predators to spot it. It is also able to puff up its body with water or air to make itself appear larger and more intimidating. It feeds on a variety of small invertebrates, including crustaceans, worms, and mollusks.
Spotted filefish can be kept in a home aquarium, but they require a large tank with plenty of hiding places and swimming space. They prefer a water temperature of 72-78°F and a pH level between 8.1 and 8.4. They are generally peaceful and can be kept with other non-aggressive fish, but they may become territorial towards other filefish. They are omnivores and will eat a variety of foods, including frozen or live brine shrimp, mysis shrimp, and algae-based foods.
Breeding spotted filefish in captivity is rare and difficult, and there is little information available on their breeding habits. They are not hermaphrodites, and male and female pairs are required for breeding. They lay their eggs on the substrate or the underside of rocks, and the eggs hatch within a few days.
