Description Trap-pest is an automatic trap to remove unwanted crabs, snails or bristle worms from the aquarium. The bristle worms crawl through narrow nets into the trap and cannot find their way out. Crabs and snails climb through a slatted curtain that only opens in one direction. The way back is blocked. The bait is easy to put into the trap from the outside. Dimensions: approx. 15.5 x 7.5 x 8.5 cm (L x W x H)
