Amazon Leaf Fish (Monocirrhus polyacanthus)

An amazing example of mimicry in nature, the Amazon Leaf Fish both looks and acts exactly like a dead leaf as a way to ambush its prey in the wild. When small fish venture too close, it extends its surprisingly large mouth and inhales them in one quick motion. In the aquarium, they make for an extremely unique display fish, especially in small groups. They are peaceful with nearly any fish too big to be eaten, but tankmates should be chosen carefully as fast-moving or aggressive fish can cause them stress. Although they are relatively hardy, feeding can be a challenge as they can be difficult to wean off live food fish or insects.
