Reedfish (Erpetoichthys calabaricus)
Also known as the ropefish or snake fish, the reedfish is an ancient species of fish related to bichir native to western Africa. Reefish usually inhabit slow-moving brackish/fresh water but can also survive in water with low dissolved oxygen content, due to a pair of lungs. These lungs allow them to survive for a small amount of time outside of the water. When they are in the water they feed nocturnally on worms, crustaceans and insects. Their peaceful and inquisitive nature and unique appearance have made the ropefish a popular fish in the aquarium trade.
