Choosing the Best Tank Mates for Snowflake Eels: A Complete Guide

Snowflake Eel Tank Mate Considerations

If you are considering adding a snowflake eel to your aquarium, it is essential to factor in their temperament, size, and tank setup when choosing compatible tankmates. Snowflake eels are territorial and can be aggressive towards others, making it crucial to select peaceful tankmates to minimize conflict.


A snowflake eel’s natural competitive nature makes them aggressive during feeding time. In a shared tank, their aggression could lead to competition for food, which may cause conflicts with other species.

Therefore, it’s important to consider feeding times when choosing tankmates.


Snowflake eels can grow up to 24 inches long, and as they grow, their prey size increases. It’s important to factor in prey size as it may impact their interaction with other species.

For example, smaller organisms like crustaceans may be seen as food options, causing conflict with other members of the tank. Parameters; Tank Setup

When designing the tank, it’s important to consider the size of the tank, hiding places, and filtration systems.

Snowflake eels require at least a 50-gallon tank. They prefer to have hiding places, like rocks and corals, to help replicate their natural habitats.

You may need a specialized filtration system to support the water quality in the tank.

The 15 Best Snowflake Eel Tank Mates

When looking to add other species to your snowflake eel tank, it is important to choose suitable fish, crabs, and other organisms that thrive and have compatible temperaments. 1.

Lionfish – relatively peaceful and have compatible predatory instincts

2. Yellow Tang – excellent algae- and detritus-eaters


Marine Betta – can thrive in the same conditions as snowflake eels

4. Picasso Triggerfish – can eat the same foods which can minimize competition

6. Emperor Angelfish – has a unique diet that does not overlap with snowflake eels, and their unique shapes complement each other.

7. Foxface Rabbitfish – Peaceful and territorial, making a good match with the less territorial snowflake eels.

8. Brittle Sea Star – bottom-dwelling species and clean-up crew that can help keep the tank clean.

9. Porcupine Pufferfish – unique shape, size, and similar dietary needs make them a good match for snowflake eels.

10. Panther Grouper – Some species can coexist with snowflake eels and have similar dietary needs.

11. Reef Triggerfish – omnivorous and are relatively peaceful.

12. Sand Sifting Starfish – a clean-up crew that lives in the substrate and can help keep the tank clean.

13. Blue Tuxedo Urchin – can help keep the tank clean and adds a unique visual element.

14. Serpent Sea Star – can help keep the tank clean and adds a unique visual element.

Temperament of Snowflake Eels

Snowflake eels have a relatively docile nature and coexist well with different marine life if other species are carefully selected. They are usually more peaceful and easygoing, provided the tank and other species’ needs are met.

Aggressiveness at Feeding Time

Snowflake eels’ natural competitive nature makes them aggressive during feeding times. During this time, it’s critical to pay close attention to their behavior to avoid conflicts with other species in the tank.

Consider feeding them separately or setting up a feeding time schedule to minimize competition.

General Docile Nature

Snowflake eels, for the most part, are docile and easygoing. It is essential to take note of their temperament, feeding times, and tank parameters when selecting other organisms to coexist with.

Proper planning and management can help reduce the risk of conflicts and ensure the health and happiness of the snowflake eels and their tankmates. In conclusion, adding compatible tankmates to your snowflake eel tank requires careful consideration of several factors, including temperament, size, and tank setup.

They are generally peaceful, but their natural competitiveness during feeding times makes it crucial to set up a feeding schedule and choose compatible species. With proper planning and management, your snowflake eels can create a unique and fascinating addition to your aquarium.

Size Requirements for Snowflake Eel Tank Mates

When considering fish and other organisms to coexist with snowflake eels, it’s essential to factor in their size. A snowflake eel will grow up to 24 inches in length, and therefore, it is recommendable to choose a minimum size of 4-5 inches for the other species in the tank.

Feeding Competition

Another factor to consider when selecting compatible tank mates for snowflake eels is feeding competition. Snowflake eels have an aggressive feeding behavior, and it’s important to ensure enough food for all the species in the tank.

Feeding times should be consistent and regular, and foods should be appropriate for each species’ dietary needs.

Parameters and Tank Setup for Snowflake Eels

Snowflake eels require specific setup and parameters to live comfortably and healthily in an aquarium. Here are some of the most significant considerations when designing your snowflake eel tank.

Minimum Tank


Snowflake eels require a 75-gallon or larger tank. They grow to over two feet in length, and an inadequate tank can cause stress, which increases the likelihood of infections and diseases.

Need for Hiding Places

Snowflake eels are natural hiders, and providing them with hiding places is crucial. Rock formations and crevices provide shelter for the snowflake eels, which can also contribute to their sense of security.

PVC pipes, caves, and tunnels can also provide suitable hiding places for your snowflake eel.

Common Tank Decorations

Snowflake eels thrive with decorations that allow them to hide and feel secure. Adding rock formations and crevices in the bottom of the tank can provide them with hiding spots.

PVC pipes, caves, and tunnels can also act as hiding places. Snowflake eels are non-aggressive towards plants, so you can add some aquatic vegetation to the tank.

Reef Tank Considerations

If you are planning a reef tank with snowflake eels, there are several things to consider. Snowflake eels are different from other species of eels, notably, moray eels, that tend to feed on live coral.

Although snowflake eels are not coral feeders, it is essential to take note of ways to prevent any damage to the coral in the tank.

Coral Damage

Snowflake eels are generally reef safe as they do not feed on coral. However, they have a unique behavior of burrowing and excavating substrates, which may affect the corals or other decorations in the tank.

Investing in epoxy putty or specialized cement can secure the corals in place or provide additional stability for them.


A well-designed filtration system is essential for a reef tank because coral is sensitive to changes in water quality. Snowflake eels produce a significant amount of waste and therefore, require filters that have enough capacity to handle the tank’s water volume.

Escape Prevention

Snowflake eels have a tendency to escape from their tanks, primarily when they are stressed or unhappy. Therefore, you should ensure that the aquarium filter’s intake and output pipes are covered.

Adding a tight-fitting lid which is adequately secured is also recommended. In conclusion, designing a comfortable and healthy environment for snowflake eels and their tankmates requires attention to detail.

Providing adequate hiding spots for your snowflake eel, selecting appropriate-sized tankmates, and designing a filtration system that takes note of the unique characteristics of snowflake eels will go a long way in ensuring their longevity and well-being. Additionally, reef tanks require special considerations, including preventing coral damage, filtration for water quality, and escape prevention.
