Care

Abbott's Moray requires a large and well-secured aquarium, as they are known to be escape artists. The tank should have plenty of rockwork and crevices for hiding, as this species is nocturnal and prefers to stay hidden during the day. They are carnivorous and should be fed a varied diet of meaty foods such as fish, squid, and shrimp. Caution should be exercised when feeding, as moray eels can mistake a hand for food and deliver a powerful bite.

Reproduction

Reproduction of Abbott's Moray in home aquariums is rare and not well-documented. In the wild, they are oviparous, with females laying eggs that are fertilized externally. The larvae are planktonic and will drift in the open ocean before settling to the bottom as they mature.

Habitat

Gymnothorax eurostus is found in reef environments throughout the Indo-Pacific, from the eastern coast of Africa to the Hawaiian Islands, and from Japan to Australia. They typically inhabit crevices in coral reefs or rocky substrates, often at depths ranging from shallow waters to about 40 meters deep.
