The Declivis Butterflyfish, also known as the Marquesan Butterflyfish, is a stunning addition to the marine aquarium. This species is found in a limited range of the Central Pacific Ocean, around the Line Islands, and is distinguished by its beautiful orange coloration that covers the dorsal half of the body and a small orange mask that covers the eyes. The remaining portions of the fish are white with black spots. This fish is relatively hardy compared to other fish species and is sure to add striking beauty to any aquarium. Moreover, the Declivis Butterflyfish adapts well to most home aquariums and is relatively easy to care for, making it an ideal choice for both experienced and novice aquarium owners.

The Declivis Butterflyfish is a unique species that should be kept in a well maintained aquarium. With its shy nature, this fish should be provided multiple hiding places in order to feel safe in its environment. An ideal aquarium size should be at least 120 gallons, and should contain plenty of live rock to provide cover and a supplemental food source. Additionally, they don’t make good candidates for reef aquariums as they tend to pick at any feather dusters, anemones, and polyps. It is important to keep the water quality high and stable in order to provide the best environment for the Declivis Butterflyfish. Furthermore, regular water changes should be done to maintain a healthy environment for the fish.

The Declivis Butterfly is a tropical butterfly that feeds primarily on coral polyps, crustaceans, and algae in the wild. In an aquarium, frozen and freeze-dried diets containing algae are good substitutes and can be supplemented with dried algae and vitamin enriched brine and mysis shrimp.
