Electric eel

The Electric Eel, which is not a true eel but rather a type of knifefish, is famous for its ability to generate powerful electric shocks. Typically, it has a dark green or bluish-black coloration, with a long, cylindrical body shaping its eel-like appearance. This species is native to the freshwater habitats of the Amazon and Orinoco River basins in South America. Despite its fascinating electrical capabilities, the Electric Eel is not commonly kept in the hobbyist aquarium due to its large size, reaching up to 8 feet in length, and its specialized care requirements, including the need for a sizeable tank and the potential risk posed by its electric shocks.
