Asian Leaf Fish
The Asian leaf fish, nandus nandus, is an obvious ambush predator. Not as good a mimic of a dead leaf as the South American leaf fish, but the Asian leaf fish is hardier and more adaptable to frozen foods. Leaf fish prefer small critters like ghost shrimp and feeder guppies. Peaceful to similar size fish, these fish are only dangerous to tank mates that fit in their mouth and think they are a leaf.
