Appearance

The Yellow-Edged Moray is a large eel with a dark brown or olive body marked with yellow margins on the fins and gill openings, giving it its common name. The body is elongated and serpentine, typical of morays, with a large mouth housing prominent teeth.

Diet and feeding

Feed frozen or fresh meaty foods such as squid, shrimp, and fish pieces. Offer 2-3 times weekly once acclimated; juveniles may require more frequent feeding.

This species is challenging for all but experienced aquarists. It requires a large, well-established tank with secure hiding, excellent water quality, and careful feeding management. Morays are predatory and will consume any fish small enough to fit in their mouth.

Common health issues

Poor water quality stress, parasitic infections, mouth/jaw damage from aggressive feeding, starvation if inadequately fed

Origin and habitat
