Versatile Use: Suitable for all types of aquariums, our planaria catching box is an essential tool for maintaining a healthy and beautiful aquatic environment. Transparent Design: The pest catching box is made of transparent material, so it does not affect the aquarium landscape and blends seamlessly into your tank's environment. Natural Solution: The Pest Catcher Aquarium Fish Grass Tank Plant Planaria Leech Removal Device provides a natural and effective way to catch planaria, snails, and leeches, helping to keep your fish tank clean and healthy. Easy to Operate: Simply pour bait into the chamber, cover with the lid, and let it sink naturally to the bottom of the tank, or hang it vertically in the aquarium. Use scenarios: After introducing plants or live foods, use the catcher to reduce hitchhiking planaria and leeches without chemicals. In planted or community tanks, place the device to target planaria and snails while preserving tank aesthetics and fish behavior. In quarantine or temporary tanks, deploy the catcher to manage pests during fish acclimation and minimize disruption to arrivals.
