Guppy Grass Live Aquarium Plant | Najas guadalupensis | Freshwater Plant

Guppy Grass is a fast-growing live freshwater aquarium plant ideal for guppy tanks, shrimp aquariums, and fish breeding setups. Its fine green leaves and branching stems form dense cover for fry, shrimp, and small fish.

Leave it floating for a natural tangle of shelter, or gently anchor stems in the substrate for midground or background coverage. It’s a simple way to add greenery to low-tech planted tanks without injected CO₂.
