Ultralife X-Terminator Mantis shrimp trap
Or If you have live rock in your aquarium, you may have introduced predatory hitchhikers like mantis shrimp or crabs to your tank. Cues are mysteriously missing fishes and strange clicking noises from the vicinity of your rocks. These pests can be difficult to remove without harming other organisms in your tank, especially sensitive reef tanks.
The Xterminator trap uses a mechanism sensitive to the slightest movements to trap these tiny menaces without interfering with larger organisms. You can adjust the sensitivity mechanism to trap larger or smaller creatures, making the Xterminator useful for all sorts of pest control situations. Don't play around with the safety of your fishes! Xterminate.
Install threaded sensitivity adjuster into the hole on top rear of trap.
Set trap by gently releasing door latch on top of trap while pushing the door inward. Door will lock into place and remain open.
The release sensitivity can be adjusted by turning adjuster clockwise (more sensitive) or counter-clockwise (less sensitive).
Place bait (krill, freeze-dried foods, etc.) into rear of trap, making sure bait remains clear of trip panel. Place baited trap into aquarium, as close to home of unwanted creature as possible. The trap will now do the rest. To release shrimp from trap, push door open with pencil until it remains open. Turn trap upside down and allow shrimp to exit the trap.
The X-Terminator is 1.5" x 5.5".
Safe for freshwater and saltwater use.
