Marine Eelincludes snowflake and other marine eel species
Marine eels have an excellent sense of smell but can't see very well. Eels have an elongated, snakelike body and vary in size and coloration. They open their jaws to allow water over their gills for breathing. A popular marine eel is the snowflake moray eel. Recommended for experienced aquarists.
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.
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.
- 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.
- 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.
- Will eat small fish and invertebrates.
- 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.
