Care

Chain Moray Eels require a specialized aquarium setup due to their size and natural behaviors. A secure lid is essential to prevent escape, and plenty of rockwork or PVC pipes should be provided for hiding places. They can grow up to 65 cm in length, so a larger tank is necessary to accommodate their size. These eels are carnivorous and should be fed a diet of meaty foods such as fish, squid, and shrimp.

Reproduction

In the wild, Chain Moray Eels are oviparous, with females laying eggs that are fertilized externally by the male. In the aquarium, breeding is rare, but understanding their natural reproductive behavior can be beneficial for overall care.

Habitat

Echidna catenata is found in the Western Atlantic from New Jersey, USA, and Bermuda to Brazil, including the Gulf of Mexico and the Caribbean Sea. They inhabit shallow reefs and rocky areas, often hiding in crevices or under rocks during the day.
