Azolla | Water Fern
Azolla | Water Fern
Azolla is a small aquatic fern that floats on the surface of still or slow-moving water. It is considered one of the fastest-growing plants on Earth, capable of doubling its biomass in just a few days under favorable conditions. This rapid growth makes Azolla an efficient nutrient absorber and a valuable tool for water purification and ecosystem management.
Azolla has a unique symbiotic relationship with cyanobacteria called Anabaena azollae. These bacteria live within specialized cavities in Azolla's leaves, where they fix atmospheric nitrogen and convert it into a form usable by plants. This nitrogen fixation ability makes Azolla a natural fertilizer, enriching the water with nutrients that can benefit other plants, algae, and aquatic organisms.
The Azolla mat provides several ecological benefits. Its dense cover shades the water, reducing light penetration and suppressing the growth of unwanted algae. This shading effect helps maintain a balanced aquatic ecosystem by preventing excessive algal blooms and the depletion of dissolved oxygen.
The Azolla mat also creates a microhabitat for a variety of organisms. It offers a refuge for small aquatic creatures like insects, snails, and amphibians, providing them with protection from predators and serving as a food source. The floating fern's fine roots dangle into the water, providing additional habitat for microorganisms, algae, and invertebrates.
Furthermore, Azolla plays a role in improving water quality. By absorbing excess nutrients such as nitrogen and phosphorus, it helps mitigate the negative effects of eutrophication, a process characterized by an overabundance of nutrients leading to algal blooms and oxygen depletion. Azolla's efficient nutrient uptake reduces nutrient availability for unwanted algae and promotes clearer and healthier water.
Beyond its ecological benefits, Azolla has gained attention for its potential in various practical applications. Due to its rapid growth and high protein content, it has been explored as a feed source for livestock and fish. It is also being investigated as a potential biofertilizer and biofuel feedstock, as its biomass can be harvested and processed into energy-rich products.
In terms of care, Azolla thrives in warm, nutrient-rich water with temperatures ranging from 68-86°F (20-30°C). It requires bright light for photosynthesis and can be easily propagated by dividing the mat or by collecting spores. Regular monitoring and maintenance may be necessary to prevent excessive growth, ensure nutrient balance, and control the spread of Azolla in sensitive ecosystems.
Overall, Azolla is an intriguing and versatile aquatic fern with a multitude of benefits. From its nitrogen-fixing capabilities and water purification properties to its role in supporting biodiversity and potential applications in agriculture, Azolla demonstrates the remarkable adaptability and ecological importance of floating plants in freshwater environments.

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
- Use a sponge filter such as Qanvee filter or a gentle flow filter to avoid strong currents that can stress shrimp.
- 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.
- 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.
- 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.
- 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:
- A container or bucket.
- An airline tube or a slow-drip system (optional).
- A net.
- Turn Off Lights: Dim the aquarium lights or turn them off completely to reduce stress on the shrimp/fish.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
