Family
Common name: Cusk-eels
Scientific name: Ophidiidae
The Ophidiidae family, commonly known as cusk-eels, encompasses a variety of elongated, bottom-dwelling fish that are found in marine environments worldwide. While not typical inhabitants of home aquariums due to their size and specialized care requirements, some smaller species may be kept by advanced hobbyists. They often require a sand or soft substrate to mimic their natural habitat where they burrow and hide. Cusk-eels are generally not aggressive but can be predatory, so tank mates should be chosen with care to avoid predation. Their diet in captivity includes meaty foods such as shrimp, squid, and fish.
