UPS: 2nd Day and Next Day shipping will be shipped outon Monday - Wednesday
Refund & DOA:
DOA (Death On Arrival): Full Refund on Fishes Cost Or Replace with another fishes. Send 2 clear photos of DOA fishes/shrimps in the bag fishes come in and photo of clear fish out of the bag within 2 hours of delivery.
Carrier Delay Shipping: If total Shipping time is more than 3 days, DOA guaranteed is voided. More Info please check https://justfishything.com/policies/refund-policy
Acclimation:
Temperature Match: Ensure the water in the bag/container your Betta came in is at the same temperature as the tank water.
Float the Bag: Float the sealed bag in the tank for about 15-20 minutes to let the water inside adjust to the tank temperature.
Water Mixing: Gradually add small amounts of tank water to the bag over the next 15-20 minutes to help the Betta adjust to the new water parameters.
Release: Gently net the Betta out of the bag and release it into the tank. Avoid adding the water from the bag into the tank to prevent any diseases from spreading.
PHOTOS: We try best to take nice photo to show best aspect of the fishes but our photo is no edit.
About 100 live daphnia to start a daphnia culture.
Cultivating Daphnia for your aquarium can be a great way to provide live food for your fish, especially for small or delicate species like Betta fish. Here’s a step-by-step guide to help you get started:
1. Set Up a Cultivation Container
• Container Size: Use a large container or tank (10–20 gallons is ideal) to allow for a stable culture. It can be a plastic bin, glass tank, or even a bucket.
• Location: Keep the container in a spot that receives indirect sunlight or use a light source for 12–16 hours a day. Daphnia thrive in moderate light.
• Water: Use dechlorinated tap water, rainwater, or aquarium water for the culture. Ensure the pH is neutral (6.5–7.5), and maintain a temperature between 65°F–75°F (18°C–24°C).
2. Aeration
• Daphnia need oxygen but don’t like strong currents. Use a gentle air stone or sponge filter to provide light aeration. Avoid strong bubbling as it can harm the Daphnia.
3. Obtain a Starter Culture
• You can purchase Daphnia starter cultures from aquarium stores, online, or collect them from ponds. Common types are Daphnia magna and Daphnia pulex.
4. Feeding Daphnia
Daphnia feed on microscopic algae and bacteria, so you’ll need to provide a food source:
• Green Water: Cultivate green water by leaving a container of water in sunlight to grow algae.
• Yeast: Mix a small pinch of baker’s yeast with water, and add it to the culture. Be careful not to overfeed, as this can cause a water quality issue.
• Spirulina Powder: A small amount of spirulina powder can be dissolved in water and fed to the Daphnia.
• Infusoria: Another option is infusoria, tiny organisms that Daphnia naturally feed on.
Feed small amounts every day, ensuring the water remains clear and doesn’t become cloudy.
5. Maintenance
• Water Changes: Perform partial water changes (10–20%) weekly to maintain water quality. Use dechlorinated water at the same temperature.
• Harvesting: Once your Daphnia population grows, you can harvest them by using a fine net or siphon. Be sure not to overharvest; leave enough to allow the culture to regenerate.
6. Temperature Control
Daphnia reproduce more quickly in warmer water but are less tolerant of extreme heat. Keep the temperature stable to avoid crashes in the population.
7. Avoiding Culture Crashes
• Do not overfeed: Excess food will rot and cause ammonia spikes.
• Maintain good aeration: Low oxygen levels can kill the culture.
• Stable temperature: Drastic changes in temperature can harm the culture.
By following these steps, you’ll have a steady supply of live Daphnia for your aquarium. It’s a nutritious and stimulating food source for Betta
