The JT Aquatics Bristle Worm Trap is a great way to keep your fish healthy and happy. This trap features a blue color, design, and construction that will appeal to any fish lover. The trap has a bait chamber at the bottom of the base to easily lure the worms into the trap. The four funnels provide multiple entrances, and the trap can catch a large number of bristle worms upon each use. For a limited time, a free small 3.78 inch x 1.5 inch trap is included for smaller tanks.
