Traditional fish traps often feature a complicated pull line mechanism that needs to be activated by hand. With the Nyos Floating Fish Trap, however, you only need to remove the outer magnet to activate the trap! After the magnet is removed, the trap will turn 90 degrees and float to the surface. This innovative design keeps your hands dry and stress levels low. It also allows for flexible positioning throughout the aquarium, especially in deep areas that would be too difficult to reach by hand.
