Trumpet Ossa Knife 

Aquarium Fish Sale offers this unusually shaped long-snouted knife fish – and do not get alarmed when it is seen unmoving on the bottom of the tank. They tend to sleep on their sides. The trumpet knife, or ossa knife, is wild caught in Peru and prefers live black worms and similar treats, and feeds primarily at night.
