Common name: Sea conger

General information

The Blackedge Conger, Ariosoma anagoides, is a species of conger eel found in the Indo-Pacific region. It is known for its distinctive dark edge along the dorsal fin and a relatively short tail. This species is not commonly kept in home aquariums but can be of interest to advanced hobbyists seeking to diversify their collection with unique and less common species.

Care

Caring for Ariosoma anagoides requires a large tank with plenty of hiding spaces, as they are nocturnal and prefer to stay hidden during the day. A sandy substrate is essential for them to burrow and feel secure. They are carnivorous and should be fed a diet of meaty foods such as fish, squid, and shrimp. Due to their potential size and predatory nature, they are not suitable for reef tanks or with small fish and invertebrates.

Reproduction

Little is known about the reproductive habits of Ariosoma anagoides in the wild or in captivity. They are presumed to have similar breeding behaviors to other conger eels, which typically involve the release of eggs and sperm into the water column for external fertilization.

Habitat

Blackedge Conger eels are typically found in the Indo-Pacific, from the Red Sea and East Africa to the Society Islands, north to southern Japan, and south to Australia. They inhabit sandy and muddy bottoms near coral reefs, often at depths ranging from shallow waters to about 90 meters deep.
