Caring for a Peacock Eel can be a rewarding experience for any freshwater aquarium enthusiast. When I first started keeping these fascinating creatures, I quickly realized how important it is to understand their unique needs, as well as the importance of proper tank setup, diet, and compatibility with tank mates.
Peacock Eels require a tank size of at least 40 gallons, with a temperature range of 75-82°F and a pH range of 6.5-7.5. They are carnivores and need a varied diet of high-quality frozen or live foods such as brine shrimp, bloodworms, and small pieces of fish or shrimp. They also require a well-decorated aquarium with plenty of hiding places and a soft substrate for burrowing.
Setting up a suitable environment for a Peacock Eel is essential for the health and well-being of your pet. It’s crucial to provide hiding spots, like rocks and caves, and ensure the substrate is soft for them to burrow.
Personally, I made the mistake of using gravel at first, but soon learned that sand is much better for their delicate bodies.
Feeding Peacock Eels a balanced and varied diet is vital for their health. I have found that frozen bloodworms and live brine shrimp are their favorites. Additionally, paying attention to potential diseases and selecting the right tank mates can make all the difference in your eel’s happiness and longevity in your care.

Species Summary
Origin
The Peacock Eel, also known as the Spiny Eel or Macrognathus siamensis, originates from Southeast Asia. They can be found in countries like Thailand, Cambodia, and Vietnam. I’ve always been fascinated by their exotic origins.
Lifespan
Peacock Eels have a relatively long lifespan, typically living up to 10 years or even more with proper care. That’s one of the reasons I was drawn to keep them as a pet.
Appearance
This eel possesses an attractive appearance, featuring a slender, elongated body with a pointed snout. Their most distinguishing feature is a pattern of eye-like spots on their body, which really caught my attention.
Size
Peacock Eels usually grow to around 8-12 inches in length, making them a manageable size for most aquarium enthusiasts. It’s also essential to provide an adequately sized tank for them to thrive.
Growth Rate
These eels generally have a moderate growth rate. From my personal experience, they reached their full size within a year and a half. Proper nutrition and a suitable environment play a significant role in their growth.
Behavior & Temperament
The Peacock Eel is a nocturnal and generally shy creature. In my tank, they usually hide during the day and become more active at night. They’re also peaceful and may get along with other non-aggressive tank mates.
Male vs Female
It’s quite difficult to differentiate between male and female Peacock Eels visually. However, females tend to be slightly plumper, especially when ready to spawn. It took me quite some time to identify the gender of my eels accurately.
Tank Setup
Tank Size
When I set up my peacock eel tank, I made sure to choose a tank with enough space. A minimum of 29 gallons is needed for a single peacock eel. Since they can grow up to 12 inches, more space is better.
Lighting
Peacock eels are nocturnal, so I provided my tank with low, dim lighting. This keeps them comfortable and reduces stress.
Filtration & Aeration
A strong filter is necessary for peacock eels since they produce a lot of waste. I used a canister filter for efficient filtration. To provide proper aeration, I added an air stone. This helps maintain a suitable oxygen level.
Heater
To mimic their natural habitat, I kept my tank temperature between 75°F and 82°F. A reliable heater and a thermometer are essential to maintain consistent temps.
Substrate
Peacock eels love to burrow, so I chose a soft, fine-grained substrate like sand. This prevents injury to their delicate bodies while they dig.
Decoration
I added hiding spots using driftwood, caves, and rocks. This allows my peacock eel to feel safe and secure during the day, encouraging natural behavior.
Plants
Adding live plants in my tank not only improved water quality but also provided additional coverage. Peacock eels prefer low-light plants that give them hiding places, such as Java Fern or Anubias.
Water Quality
Water Temperature
When I set up my Peacock Eel tank, maintaining the right water temperature was crucial. The ideal range is 74 to 82°F (23 to 28°C). I use a reliable aquarium heater and a thermometer to monitor the temperature regularly.
Water pH
Peacock Eels prefer slightly acidic to neutral water. I aim to maintain the pH level in the range of 6.5 to 7.5. To ensure accuracy, I test pH frequently using a dedicated test kit.
Water Hardness
I found that keeping the water hardness between 5 to 15 dKH works well for Peacock Eels. It’s essential to strike a balance, as both too soft and too hard water can negatively impact their health.
Water Changes
Regular water changes are a must. I replace 20% to 30% of my Peacock Eel tank water with dechlorinated water every 2-3 weeks. This practice helps keep water chemistry stable and removes excess waste and debris.
Tank Maintenance
When I first got my peacock eel, I learned quickly that tank maintenance is crucial for their health and well-being. Regular water changes play a significant role in keeping the environment clean. I change about 20-30% of the water on a weekly basis to maintain a consistent water quality.
Peacock eels are known to produce a lot of waste, so I also make sure to have a high-quality filtration system in place to remove dirt and debris. This helps maintain a stable cycle of ammonia, nitrite, and nitrate levels. Additionally, since peacock eels are sensitive to changes in water parameters, testing the water every week is essential to avoid any sudden fluctuations.
Peacock eels like to burrow, which means using a soft substrate like sand is vital. This prevents them from getting injured while they explore the bottom of the tank. Personally, I use fine-grained sand as it’s both soft and easy to clean with a gravel vacuum.
Another important aspect for my peacock eel’s tank maintenance is aquatic plants and decorations such as driftwood, rocks, and caves. These provide hiding spots and help them feel more secure. Be sure to clean them periodically to prevent algae build-up or the growth of harmful bacteria.
By keeping these factors in mind, I’ve successfully maintained a healthy environment for my peacock eel, ensuring it thrives and exhibits its unique and fascinating behaviours.
Tank Mates
Compatible Fish Species

- Tetras: Guppies, Mollies, and Platies
- Cichlids: Angelfish and Discus
- Catfish: Corydoras and Plecos
Remember, peacock eels are nocturnal, so adding daytime-active tank mates can create a well-balanced environment.
Incompatible Fish Species
While planning my tank, I also identified the incompatible fish species which should not be housed with peacock eels:
- Aggressive species: Tiger Barbs, Red-Tailed Sharks, and large Cichlids
- Fish with long fins: Betta, Gourami, and Goldfish
- Small fish: Neon Tetras, Cherry Barbs
During my experience with peacock eels, I’ve learned that incompatible tank mates can stress or injure them, and even pose a risk to their well-being. So, it’s crucial to choose your tank mates wisely.
Diet
What To Feed
In my experience, I’ve found that Peacock Eels enjoy a varied diet consisting of live or frozen foods such as bloodworms, brine shrimp, and small fish. I have also successfully offered them sinking pellets.
