Diet: Carnivore

Diet
A well-balanced marine eel diet consists of:

Frozen silversides, krill, shrimp or other carnivorous frozen options, and freezedried krill.
Squid can be given occasionally as a special meal.
Feeding
Things to remember when feeding your marine eel:

Feed once or twice a day usually in the evening.
Use caution when feeding; lower food with feeding tongs.
Thaw frozen food before feeding.

Housing
Keep in an appropriately sized aquarium; a wellsealed aquarium lid is recommended because eels can easily escape. Provide hiding places large enough for an eel to fit inside.
Stable water quality and parameters are critical to the health of aquatic life. If you are unsure of your water quality, Petco provides free water testing.

Normal Behavior
Usually marine eels are communal and sedentary.
They tend to be nocturnal and live in holes and caves.
Marine eels have a reputation as vicious hunters, but are usually harmless to humans if handled properly.

Habitat Maintenance
Daily: check filter, water temperature, specific gravity and other equipment.
Weekly: check water quality at least once a week.
Monthly: change 10 to 25% of the total volume of water every 2 to 4 weeks, or as needed.
Introduce new inhabitants to the aquarium gradually.

Compatibility
Compatible with certain species of puffers, triggers and angelfish. Don't house with small, slow-swimming species. May become aggressive in an overcrowded aquarium.
