Snowflake Eel Profile, Care, and Tank Compatibility

Snowflake moray eel

The snowflake eel is one of the most beautiful eels you can add to your tank. They're also one of the most adaptable as they don't get as large as other moray eels and their temperament is not as aggressive.

Snowflake Eel Overview

The snowflake eel, or Echidna nebulosa, is a moray eel known by a few other names including:

  • Bosch's reef eel
  • Clouded moray eel
  • Floral moray eel
  • Nebulous moray eel
  • Starry eel
  • White and zebra moray

They are native to parts of the Pacific Ocean and can be found living in reefs in the Indo-Pacific and along the western coast of the U.S., Mexico and Central America as well as by Hawaii. They typically grow to about two to three feet in length though they can get close to four feet long. The snowflake eel is recognizable for their colorful pattern which is composed of a silvery-white body with broken speckled bands of dark brown to black and yellow spotting. Their head from the eyes to the tip of the snout has no markings. The dark eyes have a yellow ring around them.

Snowflake Eel Temperament

Like many of the moray eels, the snowflake eel can become aggressive at feeding time. However it can also be one of the more placid eels compared to other morays. Some owners have even trained them to be hand-fed, though this should be done with extreme care and caution. The snowflake eel has poor vision and very strong teeth which can inflict a nasty, painful bite. Teaching the eel to associate your hands with food can have unfortunate consequences. The snowflake eel likes to spend much of its time hiding under rocks and in crevices with only the head showing. In fact it will do this most of the time when first introduced to a tank until it feels comfortable exploring more. They tend to be more active in the tank at night as they instinctively hunt for food in the evening.

The Escape Artist Snowflake Eel

One behavioral quirk of the snowflake eel that you should know from the start is their propensity for escaping their tank. They have been known to squeeze their way into any opening they can find that they can fit through. This means making sure any filter or plumbing openings in the tank are fitted with a sponge or sleeve to block entry. They can also jump somewhat out of the water, and if your tank is not covered, they can manage to get out this way. You should ensure your tank lid can be locked down or secured as they are strong enough to press against it and move it.

Snowflake Eel Care

The snowflake eel is known for adapting well to an aquarium setup. Providing that you have its basic needs met, your snowflake eel should thrive.

Snowflake Eel Tank Requirements

A snowflake eel would do best in a saltwater tank that is at least 75 gallons. Some hobbyists will keep them in smaller tanks of 50 gallons and up, but it's best to provide a larger tank as they can grow bigger, and the more you feed them the faster they will size up. They will need a setup that approximates living in a real life reef environment. This means lots of live rocks set up with places for them to hide. However, keep in mind that the eel moving around in these crevices and caves can cause rocks to move. These eels are strong so you need to make sure your setup is stable and the rock structure is impervious to the eel pressing against it or under it. Some snowflake eel keepers use cut-up sections of large PVC pipes underneath live rocks in their tanks as hiding places. They also enjoy hiding in sand so providing an area of about two to three inches in thickness in the tank would be appreciated by your snowflake eel.

Snowflake Eel Water Care

The snowflake eel needs a saltwater environment with a temperature between 70 and 80 degrees. pH should be maintained around 8.1 to 8.4, salinity/specific gravity at 1.020 and 1.026 and hardness around 8 to 12 dGH. You should also have a strong filter and a protein skimmer to keep the water clean and you will need to be ready to do frequent water changes. Snowflake eels are definitely messy and keeping on top of their water quality is vital for their good health.

Diet of the Snowflake Eel

The snowflake eel has a carnivorous diet and they need to be fed about two to three times a week. They can eat pieces of fresh or frozen clams, crab, fish, mussels, octopus, scallops, shrimp and squid. They also can eat dried or frozen krill. Never feed them feeder fish like goldfish, rosy reds or other freshwater fish as this can make them very ill. The best way to feed them is by placing the food near them with a set of long tongs, or sticking the food on a feeding stick. It's best to keep your hands well away from their mouths and the food to avoid being bitten.

Lifespan and Health of the Snowflake Eel

The average lifespan of the snowflake eel is about four years. They are generally healthy with few known medical conditions. You should occasionally add vitamins to their meals to help keep their immune system in good shape and avoid feeding them any type of freshwater fish. Make sure they are also not over fed which can lead to physical problems. They are suspect to common saltwater fish diseases brought on by poor tank management such as oxygen starvation, nitrate poisoning and ammonia poisoning.

Best Tank Mates for a Snowflake Eel

Despite the fact that they are carnivorous hunters, the snowflake eel can share a tank with other fish. Although they are considered "fish safe," you should avoid keeping any type of fish that is small enough to fit in their mouths in the event they're hungry and don't want to wait for a feeding. Avoid also any crustaceans regardless of size as they will consider these a tasty meal opportunity.

Tank Mates to Consider

They do best with large fish with semi-aggressive to aggressive temperaments. Good tank mate choices are butterflies, large gobies, groupers, large damsels, lionfish, puffer fish, tangs, large tobys, triggerfish, and wrasses. They also can live happily with other common reef invertebrates such as anemones, gorgonions, sea urchins and starfish as well as corals though they have been known to mess with corals unintentionally when moving around the tank.

Other Snowflake Eels

If your tank is large enough, you can also have more than one snowflake eel but it's best if they're both about the same size and added to the tank together. It's important to be aware that snowflake eels can become aggressive with each other, as well as to other tank mates, during feeding times. They also would not do well with most other species of moray eel, especially ones that are larger.

Learning About Snowflake Eel Care

The snowflake eel is a lovely addition to any reef tank, although they do have some specific are requirements that might make them more difficult for the novice fish keeper. They're a great choice for a first-time saltwater eel as they do not grow as large as others and other than feeding time are generally calm and less aggressive than others of their species. If you're thinking about getting a snowflake eel, take the time to make sure you have the right set up and understand all their water, diet and tank setup requirements so you can provide your eel with a long-term happy life in your care.
