This hydro-dynamic net easily and stealthily zips through the water in the aquarium to easily capture those quick and elusive fish. The five inch net is ideal for catching fish up to four inches long. The texturized grip is comfortable to hang onto as you probe the tank to find each fish. An additional great feature is the unique hook, which allows you to easily store the net on the side of the tank. The mesh net is ideal for delicate fish.
