Caridina vs Neocaridina: Which Genus Should You Keep?
Published: 2026-10-21 · FishyKart Blog
Choosing between Caridina and Neocaridina comes down to one question: how stable is your water going to be? Neocaridina (which includes cherry shrimp) tolerates a genuinely wide range of GH, pH, and TDS. Caridina (which includes Crystal Red and Tiger Shrimp) needs consistently soft, more acidic water and punishes instability far more severely.
Side-by-Side
| Trait | Neocaridina | Caridina |
|---|---|---|
| GH tolerance | Wide (6-8+ dGH) | Narrow, softer water preferred |
| pH preference | 6.5-8.0 | Typically 6.2-6.8 |
| Beginner difficulty | Easy | Intermediate/advanced |
| Example lines | Cherry, Blue Dream, Yellow | Crystal Red/Black, Tiger |
Why Neocaridina Is the Better Starting Point
The full Neocaridina water parameter range is covered in the dedicated guide - the key point here is that Neocaridina's tolerance for drift within that range gives a new keeper real margin for error. Caridina's tighter requirements mean the same small mistake (a slightly high pH swing, inconsistent remineralising) that a Neocaridina tank shrugs off can meaningfully harm a Caridina colony.
Keeping Both Together
It's possible to house both genera in one tank, but in practice the tank ends up run to Caridina's stricter standard, since Neocaridina tolerates that water fine but not vice versa. If you specifically want the easier Neocaridina experience, keep it as a Neocaridina-only tank rather than building around Caridina's needs.
