Buying Guide: Floating Plants For Betta Tanks
What to look for when buying floating plants
Light tolerance, growth rate, and surface coverage are key. Start with plants that match your tank size and lighting. Consider whether you want dense surface shade, visible texture, or nutrient removal from the water column.
Light, filtration, and placement
Floating plants benefit from medium to bright light to maintain color and growth. They can help reduce surface glare and improve water quality by uptaking nutrients before algae can use them. Place them where bettas can interact at the surface but still have open swimming space below.
Maintenance and care considerations
Expect some trimming to prevent choking surface flow. Some species spread quickly, while others stay compact. Regularly check for decay, which can alter water chemistry. Combine different textures for a natural, layered look in the tank.
Tank compatibility and safety
Avoid plants that release allelopathic compounds in sensitive setups. Choose species known to be safe with bettas and shrimp. Ensure that floating plants do not obstruct essential equipment like filters and heaters.
