Guppy Grass (Najas guadalupensis)

Guppy grass (Najas guadalupensis) is a popular fast-growing aquatic plant for freshwater aquariums.

* 🌿 Easy to grow — beginner-friendly
* 🐟 Excellent for guppies — provides hiding places for fry
* 💨 Fast-growing — helps absorb excess nutrients from the water
* 🌱 No need to plant — can be left floating or anchored
* 💡 Lighting: low to moderate light works well
* 🌡️ Temperature: roughly 18–30°C
* ✂️ Maintenance: trim regularly because it can grow very quickly

For a guppy breeding tank, guppy grass is especially useful because the dense growth gives newborn fry places to hide from adults.
