Najas guadalupensis ‘Guppy Grass’ 1-2-Grow!

Tropica's 1-2-Grow! plants come straight from the lab; they are free of algae, snails, and harmful substances, making them ideal for shrimp and sensitive fish species. They can be placed directly into the tank after rinsing off the sugary nutrient solution. Pre-soaking is not necessary.

Tropica’s 1-2 Grow! plants already grow in their underwater form in the sealed pot (unlike conventional plants from nurseries, which are usually grown above water), so that after being placed in the aquarium, they do not first have to shed some of their (above-water) leaves and develop new underwater leaves... Ideal conditions for rapid growth.

Najas guadalupensis “Guppy Grass” 1-2 Grow! is a versatile and extremely low-maintenance aquatic plant native to the USA and South America that thrives under almost all aquarium conditions. It grows quickly and propagates effortlessly, making it the ideal choice for both beginners and experienced aquarists.

This plant stands out for its slender, delicate stems and light green leaves, which create a natural, gently swaying structure in the water. It provides valuable habitat, especially in shrimp, guppy, or breeding tanks: The dense vegetation serves as a safe refuge for young fish, shrimp, and other small animals, protecting them from larger fish and offering ample surface area where they can find microorganisms and food.

“Guppy Grass” can float freely in the aquarium or be anchored in the substrate thanks to its fine roots. In doing so, it is not only decorative but also actively supports a healthy ecosystem: It absorbs excess nutrients, helps break down pollutants, and contributes to oxygen production—which sustainably stabilizes water quality.

Thanks to its adaptability, the plant thrives even in low-light aquariums and without additional CO₂ supplementation, keeping maintenance and technical requirements to a minimum. Thus, “Guppy Grass” transforms every aquarium into a vibrant, natural habitat.
