Tonina fluviatilis is an elegant aquatic stem plant known for its delicate, star-shaped leaves and refined vertical structure. Native to South America, particularly the Amazon basin. Its lime green to bright green coloration contrasts beautifully with red or darker plants. Tonina fluviatilis is best suited for advanced aquarists due to its sensitivity to water parameters and its requirement for stable, clean conditions. Propagation is straightforward through stem cuttings, which root easily in fine-grained substrates.With proper care, it adds a refined, vertical texture and vibrant tone to nature-style or Dutch-style planted tanks.
