Why Aquarium Hobbyists Love This Trap Set

• Crystal-Clear Glass Construction: Made from high-transparency glass that blends seamlessly into any aquarium. The material is erosion-resistant, non-toxic, and won't cloud your tank's appearance.
• Shrimp-Safe Tiny Openings: Openings smaller than 1mm (0.04 in) allow flatworms and leeches to enter while keeping even the tiniest juvenile shrimp safely outside.
• Smart Bottom-Capture Design: The strategically placed bottom holes take advantage of the natural movement patterns of flatworms and leeches, maximizing catch rates overnight.
• Multiple Hole Configurations Included: Get three trap styles — a 2-hole, a 3-hole, and an 8-hole design — so you can target different areas and pest population densities in your tank.
• Easy to Use & Clean: Simply add bait (liver, dead fish, shrimp, or meat), fill with tank water, and place on a perforated surface. Rinse clean the next morning and repeat as needed.
• Wide Compatibility: Works in freshwater and saltwater aquariums, shrimp-only tanks, community tanks, and planted tanks.

Frequently Asked Questions

Q: Is this planaria trap safe for shrimp and snails in my aquarium?

A: Yes! The tiny openings (under 1mm) are designed to allow flatworms and leeches to enter while keeping shrimp — including juvenile dwarf shrimp — safely outside. Snails are also too large to enter the traps.

Q: What bait should I use in the glass planaria trap?

A: Common effective baits include small pieces of raw liver, dead fish, raw shrimp, or other meaty foods. These scents attract planaria and leeches into the trap overnight.

Q: Can I use these traps in both freshwater and saltwater tanks?

A: Absolutely. The glass and plastic construction is fully compatible with both freshwater and marine (saltwater) aquarium environments.

Q: How often should I use the planaria trap to reduce the pest population?

A: For best results, use the traps nightly for 1–2 weeks during an active infestation. Once the population is reduced, weekly or bi-weekly use can help maintain a pest-free tank.

Q: How do I clean the glass leech and planaria trap?

A: Simply remove the trap from the tank, discard the caught pests, and rinse the trap thoroughly with clean water. The smooth glass surface makes cleaning quick and easy — no special tools required.
