Material: Made of high quality crystals, high brightness, acid and alkali resistance, no corrosion, it will not damage the beauty of the shrimp tank, delicate, efficient and safe. Easy to clean, hard to multiply bacteria, can be used in fresh water and salt water. Multi-hole design: Planaria traps are equipped with 3 holes, comfortable and convenient to catch inseparable planarians; whereby the plane can be effectively trapped in the tube to reduce the plane population in the tank. Usage: put bait like raw pork liver, dead fish, shrimp, meat , etc., fill the water and put it on the bottom with holes. The next day, take out the trap, clean and wash the trip, and repeat the steps. (You need to practice a little first, but when you succeed, it works great). Precise detection: crystal worm traps made of white glass, crystal clear! The mouth is smaller than 1mm and does not accidentally hurt the young shrimp. The trap tube is not straight and the trapped worms lose the chance to escape.
