Rhinomuraena Eels should be added to large well-established aquariums with plenty of stable rock work for hiding. Most Eels are nocturnal and hide in cracks and crevices during the day with only their heads sticking out. Eels will venture out during the evening looking for small fish, invertebrates and crustaceans. Do not attempt to hand feed or stick your hand in the aquarium near Eels as they may bite. When feeding use a long-handled tool with meaty foods attached waving in front of them as most Eels have poor eyesight. Provide a diet of meaty based foods along with live ghost shrimp, Grass shrimp or crabs. Keep only one Eel per aquarium as they can be quite aggressive. Provide an aquarium with a tight-fitting lid, Eels have been known to escape.
Females and male ribbon eels will have different colour variations. Juveniles are all black, females are almost all a yellow to green color and males will have a bright yellow dorsal fin with a blue body colour. They can grow up to 100cm in length.
