Ideal parameters for Neocaridina

Neocaridina davidi tolerates broad ranges, but it thrives when parameters are stable. The key is not chasing a magic number, but avoiding sudden changes and maintaining a mature environment with enough minerals for healthy molts.

1

Temperature: stable beats high

Neocaridina can live across broad ranges, but sustained heat speeds metabolism, reduces available oxygen, and can shorten lifespan. A moderate stable range usually works best for long-lasting colonies.

Avoid heat spikes.
Use cooling in summer if needed.
Do not chase high tropical temperatures.
2

GH, KH, and molting

GH provides minerals important for the exoskeleton. KH helps stabilize pH. Extreme values or sudden shifts can cause molting issues. If using RO water, remineralize in a controlled way.

Do not use pure RO water without salts.
Avoid sudden TDS increases.
Watch for complete molts.
3

TDS: useful, not absolute

TDS helps detect changes, but it does not tell you which minerals are in the water. Two tanks with the same TDS can be very different. Use it as a stability indicator, not the only criterion.

Track trends.
Do not correct every small variation.
Combine with GH/KH.
4

Water changes

Small regular changes are safer than large corrections. Matching temperature and avoiding strong mineral differences reduces stress and molting problems.

Moderate changes.
Prepared water.
No rushing.

Expert tips

Stability explains more success than any isolated value.
A mature shrimp tank is often more important than a perfect test.

Mistakes and alerts

Do not ignore these points

Do not use pure RO water.
Do not correct parameters suddenly.
Do not add shrimp to immature tanks.

FAQ

Frequently asked questions

What is the best pH for Neocaridina?

They usually do well near neutral or slightly alkaline water, as long as it is stable.

Do they need RO water?

Not always. Many colonies do well in suitable stable tap water.
