Your betta is fighting the current. This fixes that. This betta fish flow diffuser is the solution. The Fluval Spec V has great filtration but the output flow is way too strong for bettas, shrimp, and delicate plants. This 3D printed flow diffuser attaches to the output nozzle and spreads the water flow evenly - turning a harsh jet into a gentle, natural current your fish will actually enjoy. HOW IT WORKS: The linear spike nozzle design distributes water across a wide area instead of one concentrated stream. It also adjusts up to 30° side-to-side so you can aim the flow exactly where you want it. FITS: - Fluval Spec V aquarium (5 gallon) - Snaps directly onto the stock output nozzle - no modifications needed GREAT FOR: - Betta fish - reduces stress from strong currents - Shrimp tanks - keeps tiny shrimp from getting blasted around - Planted tanks - gentle flow without disturbing substrate or plants FEATURES: - Adjustable 30° side-to-side articulation - Even flow distribution eliminates dead spots - Compact, unobtrusive design that blends into your tank - Easy snap-on installation - no tools, no glue MADE TO ORDER: 3D printed fresh by Mavi's Lab.
