Aquarium Filter Baffle Flow Reducer with Suction Cups – Betta & Shrimp
Aquarium Filter Baffle & Flow Reducer for Betta, Shrimp & Small Tanks
Keep your betta fish, shrimp, and delicate aquatic plants thriving with this Anti-Suction Aquarium Filter Baffle. Designed to calm strong filter currents and intercept debris before it clogs your system, this matte black guard is a must-have upgrade for any small or nano aquarium running a hang-on-back (HOB) filtration system.
Key Features
- Non-Toxic, Food-Grade ABS Frame: Built from high-strength, food-grade ABS plastic that is corrosion-resistant and free of harmful substance release — even after years of continuous submersion. Completely safe for fish, shrimp, and live plants.
- High-Density Sponge Pre-Filter: The porous filter sponge captures fish waste, uneaten food, and suspended debris before it reaches your main filter, extending cleaning intervals and maintaining crystal-clear water.
- Strong Silicone Suction Cups: Food-grade, high-adhesion silicone suction cups grip smooth aquarium glass firmly without slipping or scratching the tank surface during long-term use.
- Universal Adjustable Fit: A reinforced carbon steel fastening screw with a sliding adjustment slot lets you fine-tune the installation distance to fit most standard HOB filter outlets — compatible with 5–30 gallon tanks with 2–3 inch diameter filter inlets.
- Unobstructed Water Circulation: Precision-punched ABS mesh outer shell allows smooth water flow through the guard while blocking large particles, preserving the full efficiency of your existing filtration system.

Frequently Asked Questions
Q: Will this aquarium filter baffle work with my hang-on-back filter?
A: Yes! The adjustable sliding slot and carbon steel fastening screw allow the baffle to fit most standard hang-on-back (HOB) filter outlets on tanks ranging from 5 to 30 gallons with inlet diameters of 2–3 inches. Simply slide and tighten to your desired position for a secure, custom fit.
Q: Is the filter baffle safe for shrimp and betta fish?
A: Absolutely. The entire unit is made from food-grade ABS plastic and food-grade silicone — materials free from harmful chemical releases even under continuous water immersion. The baffle also reduces strong water currents that can stress bettas and protects shrimp from being drawn toward the filter intake.
Q: How do I clean the sponge on this filter baffle?
A: Simply remove the sponge from the ABS housing, rinse it gently under dechlorinated or tank water to avoid destroying beneficial bacteria, and reattach it. The suction cups allow quick removal and reinstallation without tools.
Q: Will the suction cups damage or scratch my aquarium glass?
A: No. The suction cups are made from soft, food-grade silicone specifically designed to grip smooth glass surfaces firmly without scratching or marking the tank wall, even during extended use.
