FAQs
Do I need to add CO2 for Guppy Grass?
No, Najas Guadalupensis is very hardy and does not require CO2 injection to grow well.
Can I keep this in a pond?
Yes, it is excellent for outdoor ponds during warmer months, as it helps clarify water and shade inhabitants.
Will this plant kill my algae?
It outcompetes algae for nutrients, which helps reduce algae growth, but it is not a direct 'algae killer'.
Is the tissue culture gel harmful?
The gel is a nutrient-rich agar. It is non-toxic, but you should wash it off before placing the plant in the tank to prevent bacterial blooms.
How do I propagate it?
Simply cut any stem and replant it or leave it floating. Any broken piece will typically continue to grow.
Will my goldfish eat it?
Goldfish often find Guppy Grass tasty. It may serve as a supplemental food source for them.
Troubleshooting
Plant looks stringy or thin
Usually caused by low light or a lack of macro-nutrients. Increase lighting duration or add a comprehensive fertilizer.
Lower stems are turning brown or melting
This happens when the plant becomes too dense, blocking light to the bottom. Thin the clump out to allow light and flow to reach the inner leaves.
Plant is growing too fast
This is normal for Guppy Grass. Regular, heavy pruning is required to keep it from shading out other slower-growing plants.
Pros and Cons
Pros
- Completely pest-free and disease-free due to lab culture
- Excellent for biological filtration by absorbing excess nutrients
- Provides essential cover for fry and sensitive shrimp
- Extremely easy to grow in almost any aquarium environment
- Can be used as either a floating or rooted plant
Cons
- Requires frequent trimming due to rapid growth
- Can quickly overtake smaller aquariums if left unmanaged

Setup, Compatibility & Care
When you receive your 1-2-Grow cup, rinse the gel media carefully under lukewarm water until it is fully removed. Once clean, you can separate the plant into smaller portions.
Setup Instructions
- Rinse the plant thoroughly to remove laboratory gel.
- Gently untangle the strands.
- Decide on placement: use a weighted ring or plant anchor to keep it submerged, or simply release it into the surface current to float.
Care Tips
- Trimming: Use sharp, clean aquarium scissors to prune long stems. The cuttings can be replanted to propagate the colony.
- Light: While it is undemanding, moderate lighting will yield denser, faster growth.
- Nutrients: If growth slows, ensure the plant has access to basic aquarium fertilizer, specifically those containing potassium and iron.
