Floating Plants

Floating plants are an easy, natural way to enhance any pond or aquarium. They help reduce excess light, limit algae growth, and offer shade and protection for fish. Low maintenance and fast growing, they’re ideal for creating a healthy, balanced aquatic environment.

Floating Plants FAQs

Floating plants are aquatic plants that grow on the water’s surface rather than being planted in substrate. Popular varieties include Frogbit, Salvinia, Red Root Floaters, and Duckweed.

Floating plants help absorb excess nutrients, provide shade, reduce algae growth, and create cover for fish, shrimp, and fry. Their roots also offer grazing surfaces for shrimp and beneficial microorganisms.

Yes — floating plants are extremely popular in shrimp tanks. They help create a more natural environment, encourage biofilm growth, and provide shelter for baby shrimp.

Most floating plants are low maintenance and do not require CO₂. However, occasional liquid fertiliser and moderate lighting can help promote healthier and faster growth.

This is often caused by low nutrients, excessive surface movement, poor lighting, or water collecting on the leaves. Floating plants generally prefer calmer water and consistent lighting.

Yes — fast-growing floating plants can quickly cover the water surface and reduce light reaching other aquarium plants below. Regular thinning is recommended to maintain balance.

Absolutely. Bettas often enjoy the shaded environment created by floating plants, and many species use the roots as resting or hiding areas near the surface.

Gently place them on the water surface and allow them time to adjust. Avoid strong filter flow initially, and remove any damaged leaves during the acclimation period.
