Origin[edit | edit source]

South America: Amazon and Orinoco River basins, and related areas in northern South America.

Sexing[edit | edit source]

There are no known external sexual differences.

Tank compatibility[edit | edit source]

Electric Eel compatibility varies between fish. Some are happy to allow tank mates in the tank, whilst others will kill them and must be kept in a species only tank. If kept with fish they should be large fish which would not be at risk of being eaten. Adding tank mates should be done with suitable care and consideration. These fish grow large very fast, so tank mates should be of a large size to start off with to ensure they keep up with the Electric Eels growth rates.

Diet[edit | edit source]

Carnivorous, feed meaty foods such as shrimp, freshwater mussel and fish fillets. May be challenging to get to feed dead food.

Feeding regime[edit | edit source]

Feed once a day.

Environment specifics[edit | edit source]

Behaviour[edit | edit source]

An active predatory fish. Will usually spend most of their time on the substrate. They are able to take in air from the surface.
