Glass knifefish

The Glass knifefish, also known as *Eigenmannia virescens*, is a unique freshwater species native to South America. It has a distinct translucent or transparent body, often with a greenish hue, which allows it to blend into its surroundings. This fish is elongated with a knife-like shape, contributing to its name. In the aquarium hobby, it is moderately well-known among enthusiasts, especially those interested in more unusual or exotic species. Its striking appearance and interesting behavior make it a fascinating addition to home aquariums, though its care might require a bit more expertise than more common freshwater fish.
