Peacock eel, scientifically known as macrognathus siamensis, is a stunningly striking fish found in freshwater rivers throughout southeast asia. This eel-like fish features a long, slender body with iridescent hues of blue, green, and gold. If you are interested in owning a peacock eel, it is essential to understand its care requirements, tank mates, food, size, and lifespan. This informative guide will cover all the basics of peacock eel care, helping you keep this exotic species healthy and happy in your aquarium.

Peacock Eel Care


Proper Tank Size And Setup


Peacock eels are semi-aggressive fish that enjoy having plenty of space to swim around and hide. For one peacock eel, a minimum tank size of 55 gallons is recommended, with an additional 20 gallons for each additional eel. It’s essential to provide them with plenty of hiding spots, like caves and plants, as they are nocturnal and like to hide during the day.

Also, avoid keeping them with aggressive fish to prevent any confrontations.

Water Quality Requirements


Peacock eels are sensitive to poor water quality, so maintaining good water conditions is crucial. It’s advised to keep ph levels between 6. 5 and 7. 5, with water hardness around 10 dgh. Regular water changes of at least 25% every week can help keep their environment clean.

Temperature And Lighting Preferences


Peacock eels prefer a temperature range between 72°f to 82°f, with a ph range of 6. 5 to 7. 5 and water hardness around 10 dgh. They don’t like bright lighting and prefer low light environments. It’s important to provide a suitable habitat to ensure that they are healthy and stress-free.

Recommended Filtration And Aeration


Peacock eels are sensitive to poor water conditions, so a well-functioning filter is essential for their survival. A canister filter is an ideal choice as it provides excellent water flow and filtration. Also, proper aeration is essential to maintain good water quality and keep the oxygen levels in check.

A quality air pump with an air stone can help achieve this.

Tips For Acclimating New Peacock Eel


Peacock eels are sensitive to changes in their environment, so careful acclimation is necessary. Start by floating the closed bag containing the eel in their tank for about 30 minutes. Then open the bag and let some aquarium water into the bag gradually.

Repeat the process every 10 to 15 minutes until the bag is almost full. After that, use a net to transfer the eel from the bag to the tank gently. Also, avoid feeding them within the first 24 hours to allow them time to adjust to their new surroundings.

By providing proper care, maintaining good water quality, and adhering to their specific needs, a peacock eel can thrive in your aquarium for many years.

Peacock Eel Tank Mates


Peacock eels, with their elongated and slender bodies, are fascinating to keep as pets for both beginner and experienced aquarists alike. Although these freshwater fish are typically peaceful and non-aggressive, keeping them with the right tank mates is essential to ensure their wellbeing and prevent injury.

Compatibility With Other Fish Species


Peacock eels are peaceful creatures that prefer slow-moving water, but their compatibility with other fish species can be mixed. Medium-sized fish with similar temperaments to the peacock eel often make the best tank mates, while larger and more aggressive fish should be avoided.

Recommended Tank Mates


Here are some fish species that make great companions for peacock eels:

  • Gouramis – these fish share the peacock eel’s peaceful temperament and slow swimming speed, making them great tank mates.
  • Corydoras – small, bottom-dwelling fish like corydoras are unlikely to bother the peacock eel and add interest to the lower parts of the tank.
  • Tetras – neon tetras and other small tetra species are peaceful and have a similar swimming style and water temperature ideal for peacock eels.

Fish To Avoid


Peacock eels do not tolerate being bullied by other fish and may try to retaliate if cornered.

  • Cichlids – this group of fish can be territorial and aggressive, which should clash with the peaceful nature of the peacock eel.
  • Loaches – although peaceful, loaches are bottom-dwelling fish that can become aggressive towards other bottom-dwelling species such as peacock eels.
  • Barbs – the active and sometimes aggressive nature of barbs can create conflict with the gentle and slow-moving peacock eel.

So if you’re planning to keep a peacock eel, make sure to select the right tank mates. This will ensure a harmonious and healthy aquarium environment for all your aquatic pets.

Peacock Eel Food


Peacock eels are omnivores, which means they eat both plants and animals. In the wild, they feed on insect larvae, crustaceans, algae, and small fish. In captivity, it’s important to provide them with a healthy and balanced diet that meets their nutritional requirements.

Nutritional Requirements


Peacock eels need a well-balanced diet that includes protein, fiber, vitamins, and minerals. A healthy diet will help to maintain their immune system, digestive system, and overall health. A lack of proper nutrition can lead to various health problems, including stunted growth, malnutrition, and infections.

Feeding Frequency


Peacock eels are not heavy feeders, and they should be fed once a day. Overfeeding can lead to obesity and health issues, so it’s essential to monitor their appetite and adjust their feeding schedule accordingly.

Suitable Food Options


The best food options for peacock eels are live or frozen food. They prefer meaty and protein-rich foods like shrimp, bloodworms, krill, and brine shrimp. You can also feed them a variety of sinking pellets and flakes, but live food is always the best option for a balanced diet.

Tips For Feeding Peacock Eel


  • Avoid feeding them too much at once.
  • Make sure the food has reached the bottom of the tank before they start eating.
  • Offer a variety of food to keep them interested and healthy.
  • Remove any uneaten food to prevent contamination and maintain water quality.
  • Feed them at the same time every day to establish a routine.

A well-balanced diet is crucial for the health and longevity of peacock eels. Providing them with suitable food options, following a feeding schedule, and maintaining the water quality will ensure they live a healthy and happy life.
