Declivis Butterflyfish

The Declivis Butterflyfish (Chaetodon declivis) is a relatively small and peaceful saltwater fish that can reach up to 6 inches in length. This species is usually found in the coral reefs of the central and western Pacific Ocean. It has a white to yellowish body with black diagonal stripes on its sides, and a yellow tail. The Declivis Butterflyfish is a popular choice for aquarium enthusiasts due to its colorful and striking appearance.

In the wild, the Declivis Butterflyfish feeds on a diet of small invertebrates such as crustaceans, mollusks, and worms. In an aquarium setting, it can be fed a variety of foods including frozen or live brine shrimp, mysis shrimp, krill, and other small crustaceans. It is important to provide a varied diet to ensure the fish receives all the necessary nutrients.

There is no visible difference between male and female Declivis Butterflyfish.

Breeding and spawning of the Declivis Butterflyfish is not common in captivity. It is a pelagic spawner, meaning it releases eggs and sperm into the water column where fertilization takes place. The fertilized eggs hatch into larvae, which will drift in the ocean currents before settling on a suitable habitat.

The Declivis Butterflyfish is relatively hardy and not prone to many common diseases if kept in a healthy environment. However, it can be susceptible to parasitic infections, bacterial infections, and ich. It is important to maintain good water quality, provide a balanced diet, and avoid overcrowding to prevent diseases.

The Declivis Butterflyfish is found in the central and western Pacific Ocean, specifically in the waters of Japan, the Philippines, Indonesia, and Australia.

The Declivis Butterflyfish is generally a peaceful fish and can be kept with other non-aggressive species. However, it may become territorial towards other butterflyfish, particularly those of the same genus. It is important to provide adequate hiding places and territories for each fish.

Proper acclimation is crucial when introducing a Declivis Butterflyfish to a new aquarium. The fish should be slowly acclimated to the new water conditions by floating the bag in the aquarium for about 30 minutes to equalize the temperature. Then, small amounts of aquarium water should be added to the bag over a period of time, allowing the fish to adjust to the new water chemistry.
