Guppy Grass (Najas guadalupensis) is a fast-growing, low-maintenance freshwater aquarium plant popular among shrimp keepers, fish breeders and planted aquarium enthusiasts. Its delicate, branching stems create dense green cover, making it an excellent choice for Cherry Shrimp tanks, Caridina shrimp aquariums, guppy breeding tanks and low-tech planted aquariums.

Unlike many aquarium plants, Guppy Grass can grow freely floating in the water or loosely anchored in the substrate. It requires no CO₂ injection and adapts to a wide range of freshwater conditions, making it suitable for beginners and experienced aquarists.

Why Guppy Grass Is Excellent for Shrimp Tanks

At AUShrimpHome, we particularly value aquarium plants that provide natural hiding places and grazing surfaces for freshwater shrimp.

Guppy Grass develops a dense network of fine stems and leaves where biofilm and beneficial microorganisms can grow. These provide valuable natural grazing areas for adult shrimp and newly hatched shrimplets.

Its thick growth also offers important shelter for:

  • Baby shrimp (shrimplets): Providing protection and access to natural food sources.

  • Freshly moulted shrimp: Offering hiding places while their new exoskeleton hardens.

  • Berried females: Creating sheltered areas where they can retreat when disturbed.

  • Baby fish (fry): Providing dense cover that can improve their chances of avoiding predators.

From our experience maintaining hundreds of shrimp breeding tanks, providing plenty of hiding places is an important part of supporting healthy shrimp colonies.

Fast Growth & Natural Nutrient Absorption

One of the biggest advantages of Guppy Grass is its rapid growth and ability to absorb dissolved nutrients from aquarium water.

As it grows, Guppy Grass takes up nutrients such as nitrates and phosphates, helping reduce excess nutrient availability that could otherwise contribute to algae growth.

However, Guppy Grass does not replace proper filtration, aquarium cycling or regular water maintenance.

Because it grows quickly, occasional trimming is recommended to prevent it from covering too much of the aquarium and blocking light from other plants.

Guppy Grass Care & Growing Requirements

Guppy Grass is one of the easiest freshwater aquarium plants to maintain.

It grows under low to high lighting, although moderate lighting generally encourages faster, denser growth.

CO₂ injection is not required, making it an excellent choice for low-tech shrimp tanks.

You can grow Guppy Grass in several ways:

  • Floating: Allow it to grow freely throughout the aquarium.

  • Loosely anchored: Position stems among rocks, driftwood or decorations.

  • Planted: Gently place stems into the substrate, although they may detach easily.

Its fast growth makes it particularly useful for breeding tanks where dense vegetation and natural cover are desired.

How to Take Care The Shrimps

Taking care of Freshwater aquarium Shrimps (Neocaridina and Caridina) involves providing them with a suitable environment and proper attention to their specific needs. Here are some essential care guidelines:

1. Tank Setup:

  • Shrimp are relatively small and can be kept in tanks as small as 5 gallons (19 liters), but a larger tank allows for more stable water conditions.
  • Provide hiding spots with plants, driftwood, and rocks. Live plants like Java Moss and Java Fern are ideal as they serve as both hiding places and a food source.

2. Water Parameters:

For Neocaridinar (Cherry Shrimps)

  • Temperature: 72-78°F (22-28°C)
  • pH: 6.5-7.5
  • GH (General Hardness): 6-10
  • KH (Carbonate Hardness): 3-10

For Caridina (Taiwan bee, Crystal Shrimps)

  • Temperature: 72-78°F (22-26°C)
  • pH: 6.0-6.5
  • GH (General Hardness): 3-5
  • KH (Carbonate Hardness): 0-10

3. Filtration:

  • Use a sponge filter such as Qanvee filter or a gentle flow filter to avoid strong currents that can stress shrimp.

4. Feeding:

  • Shrimp are omnivores and feed on algae, biofilm, and commercial shrimp pellets.
  • Supplement their diet with blanched vegetables like Mulberry leaves, spinach or zucchini.
  • Offer a varied diet to ensure proper nutrition.

5. Water Changes:

  • Perform regular water changes (10-20% weekly) to maintain water quality.
  • Use dechlorinated water at the same temperature and parameters as the tank.

6. Molting:

  • Provide a calcium source, such as our shrimp mineral products or crushed coral, cuttlebone, to support molting.

7. Tank Mates:

  • Shrimp are generally peaceful but can be preyed upon by larger fish.
  • Suitable tank mates include small, non-aggressive fish like guppies or endlers.
  • Avoid aggressive or predatory species.

8. Breeding:

  • Shrimp breed readily in captivity.
  • Provide moss or other dense plant growth for shrimp to hide their eggs.
  • Maintain stable water conditions to encourage breeding.

9. Health and Observation:

  • Regularly observe your Shrimp for signs of stress, illness, or abnormal behavior.
  • Quarantine new arrivals to prevent introducing diseases.

10. Patience:

  • Shrimp keeping can be rewarding but requires patience. Allow your aquarium to mature and stabilize before adding shrimp.

By following these care guidelines, you can create a thriving environment for your Shrimp and enjoy their vibrant colors and fascinating behavior in your aquarium.

How to Acclimate New Shrimps & Fish

Acclimating new aquarium shrimp/fish is crucial to ensure a smooth transition and minimize stress. Follow these steps for proper acclimation:

Materials Needed:

  • A container or bucket.
  • An airline tube or a slow-drip system (optional).
  • A net.

Procedure:

  1. Turn Off Lights: Dim the aquarium lights or turn them off completely to reduce stress on the shrimp/fish.
  2. Float the Bag: Place the sealed bag containing the shrimp on the surface of the aquarium water. This allows the water inside the bag to gradually adjust to the tank temperature.
  3. Drip Acclimation (Optional): If you have an airline tube or a slow-drip system, set it up to provide a gentle flow of water from the tank into the bag. This method is slower but provides a more gradual transition. Adjust the flow rate to about 2-4 drops per second.
  4. Monitor Temperature: Ensure the water temperature inside the bag matches the tank temperature after about 15-20 minutes. This step is essential to prevent temperature shock.
  5. Open Bag and Add Tank Water: Carefully open the bag without allowing shrimp to escape. Using a net or your hand, gently transfer the shrimp into a clean container or bucket. Be cautious not to introduce water from the bag into the container.
  6. Gradual Water Exchange: Over the course of about 30 minutes to an hour, gradually add small amounts of aquarium water to the container with the shrimp/fish. This helps the shrimp adjust to the tank's water parameters.
  7. Net Transfer: After acclimation, use a net to transfer the shrimp from the container into the main aquarium. Avoid adding any water from the acclimation container into the tank.
  8. Dispose of Bag Water: Safely dispose of the water from the bag. Do not release it into your aquarium, as it may contain contaminants or pathogens.
  9. Observe and Monitor: Keep an eye on the newly introduced shrimp/fish for the next few hours to ensure they adapt well to their new environment. Monitor their behavior and look for any signs of stress or illness.

Proper acclimation helps reduce the risk of shock and ensures a smoother transition for your new aquarium creatures. It's an essential step in ensuring their health and well-being in your tank.
