General information

The Dragon Sea Moth, scientifically known as Eurypegasus papilio, is a fascinating and unique species within the Pegasidae family. This small, bottom-dwelling fish is known for its peculiar appearance, resembling a mix between a dragon and a moth. It has large, wing-like pectoral fins and a body covered in bony plates, which provide protection from predators. The Dragon Sea Moth is a slow-moving species that uses its modified pelvic fins to 'walk' along the substrate.

Care

Caring for Dragon Sea Moths in a home aquarium requires attention to detail, as they are delicate and have specific needs. They thrive in tanks with a sandy substrate and plenty of hiding places. These fish are not strong swimmers, so a gentle water flow is essential to prevent stress. They primarily feed on small crustaceans and other tiny invertebrates, so a well-established tank with live rock can provide natural feeding opportunities. Supplemental feeding with live or frozen foods may be necessary to ensure proper nutrition.

Reproduction

Little is known about the reproductive habits of the Dragon Sea Moth in the wild or in captivity. However, like many marine fish, they are likely to have a pelagic larval stage, where the young are dispersed by ocean currents before settling to the bottom as they mature.

Habitat

Dragon Sea Moths are found in the Indo-Pacific region, typically in shallow waters near coral reefs or seagrass beds. They prefer habitats with sandy or muddy substrates where they can camouflage and search for food. Their distribution ranges from the Red Sea and East Africa to the western Pacific Ocean.
