Appearance

A slender, eel-like fish with a pale tan to light brown body marked by a distinctive single dark stripe running the length of the body. The head is small and pointed, typical of garden-eel morphology, with the dorsal fin extending along most of the back.

Diet and feeding

Feeds primarily on small zooplankton and small crustaceans in the wild. In captivity, offer small frozen foods such as mysis shrimp, copepods, and amphipods multiple times daily, preferably using a feeding pipette near the fish's burrow.

Difficulty and care for the Onestripe Wormfish

Moderately challenging for hobbyists. Requires a deep sand bed for burrowing, stable water conditions, and a reliable supply of small live or frozen planktonic foods. Generally hardy once acclimated, but prone to starvation if not fed appropriately.

Common health issues

Starvation, parasitic infections, bacterial disease from poor water quality

Origin and habitat

Indo-Pacific from the Red Sea and East Africa to Hawaii and French Polynesia, found on coral reef slopes and drop-offs at depths of 20–60 meters.
