About
Eigenmannia virescens is a widespread Gymnotiform knife fish native to rivers and streams throughout South America. Its near-transparent body and pale green iridescence, combined with remarkable locomotive agility, make it an endlessly fascinating observation fish. It is less aggressive than many knife fish and can be kept in small groups given sufficient space.
