No photo yet
The silver arowana from the Amazon and the Guianas (absent from the Rio Negro, home of the black arowana) is a surface predator famous for leaping out of the water to catch insects. In the wet season it moves into flooded forest. The male mouthbroods the eggs and fry. It is a food fish, and juveniles are sold for aquaria, but it grows too large for a home aquarium.
