Basic rule of thumb for beginners

For those new to keeping Neocaridina Red Onyx shrimp, here’s a simple rule of thumb to follow:

2-5 shrimp per gallon for tanks under 20 gallons 5-10 shrimp per gallon for larger tanks (20+ gallons)

These guidelines provide a conservative approach that allows for some margin of error as you learn to maintain your shrimp tank. Starting with lower numbers gives you room to adjust and helps prevent overstocking issues.

Differences between Neocaridina and Neocaridina Red Onyx stocking rates

While Neocaridina Red Onyx are a color variant of Neocaridina davidii, their stocking rates are generally similar to other Neocaridina species. However, it’s worth noting that some hobbyists find Red Onyx to be slightly more sensitive than other color morphs. As such, it may be wise to err on the side of caution and stock at the lower end of the recommended range when starting.

Why it depends

The actual number of shrimp your tank can support depends on various factors:

1. Filtration efficiency: Better filtration can support higher bioloads.
2. Plant density: Heavily planted tanks can accommodate more shrimp.
3. Maintenance routine: Regular water changes allow for higher stocking levels.
4. Feeding habits: Overfeeding can lead to water quality issues, limiting stocking potential.
5. Individual shrimp size: Larger adult shrimp have a greater impact on bioload than juveniles.
6. Breeding goals: Lower stocking densities may be preferred for focused breeding projects.

Minimum Tank Size Requirements for Neocaridina Red Onyx

General recommendations for beginners

For those just starting with Neocaridina Red Onyx shrimp, here are the recommended minimum tank sizes:

Recommended: 10 gallons (38 liters) tank Minimum: 5 gallons (19 liters) tank

A 10-gallon tank is recommended for beginners as it provides more stable water parameters and room for error. This size allows for a comfortable starting colony of 20-50 shrimp, with room for growth.

While a 5-gallon tank is an absolute minimum, it requires more careful management and limits your colony size. In a 5-gallon setup, start with no more than 10-15 shrimp to ensure optimal conditions.

Remember, larger tanks are generally easier to maintain and provide a better long-term environment for your Neocaridina Red Onyx shrimp. As you gain experience, you can adjust your stocking levels based on your tank’s specific conditions and your maintenance abilities.

With more water, pollutants are diluted more effectively, and temperature fluctuations occur more slowly, reducing stress on your shrimp.

More space for hiding and foraging

A bigger tank allows for a more diverse and complex aquascape. You can include more plants, driftwood, and hiding spots, mimicking the shrimp’s natural habitat. This extra space encourages natural behaviors and reduces competition for resources among your shrimp.

Better opportunities for natural behaviors

With more room, your Red Onyx shrimp can exhibit a fuller range of natural behaviors. They’ll have ample space for molting, breeding, and exploring. This freedom can lead to healthier, more active shrimp and potentially better breeding results.

Easier maintenance and parameter control

While larger tanks require more effort during water changes, they generally need less frequent maintenance. The increased water volume provides a margin for error, making it easier to maintain stable parameters. This can be especially beneficial for beginners still learning the nuances of shrimp keeping.

Challenges of Smaller Tanks

While smaller tanks can be suitable for experienced keepers, they come with several challenges:

Rapid parameter fluctuations

In smaller volumes of water, any changes to water chemistry occur more quickly and dramatically. A missed water change or slight overfeeding can rapidly lead to dangerous spikes in ammonia or nitrates, potentially stressing or harming your Red Onyx shrimp.

Limited space for population growth

Neocaridina shrimp can breed prolifically under the right conditions. In a small tank, population growth can quickly lead to overcrowding. This can stress the shrimp and may require you to regularly cull or rehome individuals to maintain a healthy colony.

Increased stress on shrimp

Limited space can lead to increased competition for resources and hiding spots. This can cause stress among your Red Onyx shrimp, potentially leading to reduced breeding, slower growth, or even increased mortality rates.

Higher maintenance requirements

Smaller tanks require more frequent water changes and closer monitoring of water parameters. The margin for error is much smaller, meaning that even minor neglect can have significant consequences. This higher maintenance demand can be challenging, especially for newcomers to the hobby.

While smaller tanks can be successful with diligent care and experience, larger tanks generally provide a more forgiving environment for Neocaridina Red Onyx shrimp.

Increased aggression or stress

• Shrimp constantly hiding or clustering in corners
• Frequent molting issues or deaths after molting
• Unusual swimming patterns, like erratic movements or swimming at the surface
• Increased occurrence of “whitening” or loss of color in shrimp

Reduced breeding

• Fewer berried females were observed in the colony
• Smaller clutch sizes in berried females
• Higher mortality rates among newly hatched shrimplets
• Slower growth rates in juvenile shrimp

Scaling Up: When and How to Upgrade Your Neocaridina Red Onyx

Tips for safely transferring Neocaridina Red Onyx to a larger tank

1. Cycle the new tank fully before transferring the shrimp
2. Match water parameters closely between old and new tanks
3. Acclimate shrimp slowly using the drip method over 1-2 hours
4. Transfer some of the old tank water and filter media to seed the new tank
5. Move decorations and plants to provide familiar hiding spots
6. Avoid feeding for 24 hours after transfer to allow shrimp to settle

Gradual colony expansion strategies

1. Start with a small group in the new tank:
   • Transfer 20-30% of your colony initially
   • This allows you to monitor for any issues in the new setup
2. Staged transfer approach:
   • Move shrimp in batches over several weeks
   • This minimizes stress and allows for adjustments if needed
3. Focus on juveniles and sub-adults:
   • These are often more adaptable to new environments
   • Keep some adults in the original tank to maintain breeding
4. Monitor and adjust:
   • Observe the transferred shrimp closely for the first few weeks
   • Make small adjustments to water parameters or feeding as needed
5. Gradual parameter shifts:
   • If the new tank has slightly different parameters, adjust them slowly over time
   • Aim for no more than 0.2 pH change or 10 TDS change per week
6. Breeding control:
   • Consider separating males and females in the old tank to control population growth
   • This allows you to manage the expansion rate more effectively

By following these strategies, you can safely scale up your Neocaridina Red Onyx colony while minimizing stress and maximizing the health of your shrimp. Remember, patience is key when expanding your shrimp-keeping endeavors.
