The starry night eel is a completely freshwater eel with a spotted pattern like the stars in the sky. These eels are caught in slow-moving streams that feed Lake Tanganyika in the Congo delta. Starry night eels are peaceful and will eat frozen foods, but they are known to eat very small tankmates if they fit in their mouth. These eels are not nippers and get along well with cichlids, rainbowfish, sailfin molly, and other fish of similar size.

Care Guide
Tank setup: Spiny eels like to burrow, so give them a soft sand bottom, plants and hiding places. They are expert escape artists, so a tight-fitting lid is a must.
Feeding: Feed frozen foods like bloodworms and brine shrimp once a day. Some learn to take sinking pellets.
Tankmates: They are peaceful but will eat very small fish. Keep them with community fish too large to fit in their mouth.
Good to know: Starry night eels are true freshwater spiny eels, not real eels, and they like to burrow with just their head poking out.
