Common name: Ribbon eel

General information

The Ribbon Eel (Rhinomuraena quaesita) is a striking and unique species known for its elongated body and high-contrast coloration. Juveniles and males are typically a vibrant blue with a yellow dorsal fin, while females transition to a yellow or greenish-yellow hue. This species is a sequential hermaphrodite, starting life as males and potentially changing to females as they mature.

Ribbon Eels are often mistaken for sea snakes due to their slender bodies and undulating swimming style. They are a member of the Muraenidae family, which includes other moray eels, but are notable for their more peaceful demeanor and distinctive appearance.

Care

Ribbon Eels can be challenging to keep in home aquariums due to their specialized care requirements. They need a large tank with plenty of hiding places and a tightly sealed lid, as they are known escape artists. These eels are carnivorous and prefer live foods, which can make feeding difficult. It's essential to monitor their feeding closely, as they can be picky eaters and may refuse food if stressed.

Reproduction

In the wild, Ribbon Eels are oviparous, with females laying eggs that are fertilized externally. However, breeding Ribbon Eels in captivity is extremely rare and not well-documented. Their complex life cycle and sex change make reproduction a challenge for even the most experienced aquarists.

Habitat

Ribbon Eels are found in the Indo-Pacific region, from East Africa to the southernmost islands of Japan and Australia. They inhabit lagoons and coral reefs, often burrowing into sandy substrates or hiding in crevices. They are typically seen with only their heads protruding from their burrows, waiting to ambush prey.
