The Fire Eel is a freshwater species. It is in fact a fish, not a true eel, but is called an eel due to its appearance. Native to South East Asia, the Fire Eel is a nocturnal predatory fish. This impressive fish has a growth on the end of its nose that it uses to search for food on the aquarium floor. It has two large nostril tubes at the end of it's nose making for an intriguing appearance.

Fire Eels prefer temperatures between  24 - 28° C. A Thermometer is recommended to monitor the water temperature.

Soft sand is a good substrate for Fire Eels. They enjoy burrowing, digging and searching for food in the substrate.

A variety of Substrates are available at Coburg Aquarium. 


Fire Eels require structure to hide in. Create hiding places in the aquarium with driftwood, rock, piping and caves. This helps reduce stress as this is a natural behaviour. As they are active substrate diggers, plants such as anubias or microsorium can be kept, but must be fixed to wood or rock. Alternatively, opt for floating plants.
