Black Crystal Shrimp (Caridina cantonensis)

Caridina Shrimp Care Guide with Aquarium Size Requirement:

1. Species Overview:

• Caridina shrimp, such as Caridina cantonensis (commonly known as Crystal Red Shrimp or Crystal Black Shrimp), are popular freshwater shrimp in the aquarium hobby. They are known for their striking colors and patterns.

2. Aquarium Size:

• A tank of at least 5 gallons is recommended for a small colony of Caridina shrimp. Larger tanks are preferable if you plan to keep a larger colony or other tank mates.
• These shrimp thrive in a species-only setup or with other small, peaceful fish.

3. Water Parameters:

• Maintain water temperature between 68°F and 74°F (20°C to 23°C).
• Keep the pH between 6.0 and 6.8.
• Water hardness should be soft, with a range of 1 to 4 dGH.
• The presence of tannins in the water, from sources like Indian almond leaves or driftwood, can be beneficial.

4. Aquarium Setup:

• Provide plenty of plants, mosses, and hiding spots with decorations like driftwood and rocks to create a natural habitat.
• They prefer a well-planted tank with fine substrates like sand or shrimp-specific substrates.
• Ensure gentle water flow and a reliable, shrimp-safe filtration system.

5. Diet:

• Caridina shrimp are omnivorous and will accept a variety of foods. Offer high-quality shrimp pellets, algae wafers, and blanched vegetables as the staple diet.
• Supplement their diet with biofilm, detritus, and occasional protein sources like baby brine shrimp or daphnia.
• Feed them small amounts 1-2 times a day, removing uneaten food to prevent water quality issues.

6. Tank Mates:

• They are best kept with other peaceful invertebrates or small, non-predatory fish like otocinclus, small rasboras, or other Caridina shrimp.
• Avoid aggressive or large fish that may prey on them.

7. Shrimp Size:

• Adult Caridina shrimp typically reach a size of 1 to 1.5 inches (2.5 to 3.8 centimeters) in length.

8. Disease Prevention:

• Maintain excellent water quality with regular water changes and proper filtration to prevent diseases.
• Quarantine new shrimp before introducing them to the main tank to avoid spreading diseases.
• Monitor for signs of stress or illness, such as lethargy, color loss, or unusual behavior, and take appropriate action if needed.

By following these care guidelines, you can ensure a healthy and thriving environment for your Caridina shrimp in your aquarium.
