Red Crystal Shrimp (Caridina cantonensis var. "Red Crystal") is a selectively bred freshwater shrimp species highly prized in the aquarium hobby for its vibrant red coloration and ornamental value. They belong to the Caridina genus and are a variation of the Bee Shrimp (Caridina cantonensis), which also includes other popular variants like Crystal Red Shrimp (CRS) and Crystal Black Shrimp (CBS).
Keeping Red Crystal Shrimp, a variety of Caridina shrimp, requires attention to water parameters, diet, and tank setup. Here's a comprehensive guide:
Tank Setup:
- Tank Size: Start with at least a 5-gallon tank, but larger tanks provide more stability.
- Substrate: Use buffering substrate like ADA Amazonia to maintain stable pH and provide essential minerals.
- Plants: Include live plants like Java moss, Anubias, and moss balls for grazing and hiding spots.
- Filtration: Use a gentle filter to prevent shrimp from getting sucked in. Sponge filters are popular choices.
-
Water Parameters: Maintain stable conditions:
- pH: 6.0-7.0
- Temperature: 68°F-74°F (20°C-23°C)
- GH: 4-6
- KH: 0-2
Diet:
-
Varied Diet: Offer a balanced diet including:
- Algae: Allow algae growth for grazing.
- Specialized Foods: Provide shrimp pellets, blanched vegetables (like zucchini or spinach), and quality shrimp food.
- Occasional Treats: Offer treats like boiled spinach, spirulina, or calcium-rich foods like cuttlebone.
- Feeding Frequency: Feed small amounts once a day or every other day. Adjust based on observed consumption.
Water Changes and Maintenance:
- Regular Water Changes: Perform weekly water changes of around 10-20% to maintain water quality.
- Water Conditioner: Use a water conditioner to remove chlorine and chloramines.
- Monitoring: Regularly test water parameters to ensure stability.
Tank Mates:
- Species Compatibility: Avoid aggressive or predatory tank mates.
- Shrimp Safe Fish: Consider small, peaceful fish like small tetras or dwarf rasboras.
- Solo Setup: Keeping Red Crystal Shrimp alone or with other shrimp species is ideal.
Acclimation:
- Slow Acclimation: Drip acclimate new shrimp to prevent shock from sudden changes in water parameters.
- Quarantine: Quarantine new shrimp to prevent introducing diseases to your main tank.
Observation and Care:
- Behavioral Observation: Monitor shrimp behavior for signs of stress, disease, or molting issues.
- Remove Molts: Remove molts promptly to prevent ammonia spikes.
Breeding:
- Ideal Conditions: Provide stable water parameters and ample hiding spots for successful breeding.
- Separate Breeding Tank: Consider a dedicated breeding tank to protect offspring from predation.
By following these guidelines and providing a suitable environment, diet, and care, you can successfully keep and breed Red Crystal Shrimp in your aquarium. Regular maintenance and observation are key to their health and well-being.
