Shrimp comparison
Neocaridina vs Caridina Shrimp — Which Should You Keep?
Invertebrate
If you want shrimp that breed in a tap-water planted tank, buy Neocaridina. If you want crystal bees, you are signing up for RO water and a remineralizer — not a harder cherry.
- Neo = tap-ish
- Caridina = RO
- Never copper
- One colony per tank
Quick facts
| Neocaridina | Cherry, yellow, blue dream — GH ~6–14, pH ~6.8–7.8 |
|---|---|
| Caridina | Crystal red/black, Taiwan bee — often GH 4–6, KH near 0, pH ~6.0–6.8 |
| Water source | Neo: aged tap if soft–moderate. Caridina: RO + dedicated salts |
| Temperature | Neo 20–26 °C. Caridina often happier 20–23 °C |
| Breeding | Neo: easy in a cycled tank. Caridina: possible, slower, water-sensitive |
| Price | Neo cheap. High-grade Caridina costs real money |
| Copper | Fatal to both. No plant ferts with copper; no old meds |
| Mixing | Do not dump both into one tank — parameters + hybridization mess |
Overview
These are not two colors of the same shrimp. Neocaridina davidi (cherry) is the hardy grazer. Caridina bee/crystal lines want low KH, remineralized RO, and cooler stability. Treating Caridina like “fancy cherry” is how whole colonies crash after a tap change.
Cherry deep-dive: cherry shrimp care. Algae crew: Amano (different genus, does not breed in freshwater). Fish with shrimp: tank mates. Cycle first: fishless cycle.
How to choose
-
Step 1
Pick the water you can actually run
If you will not buy an RO unit and TDS meter, choose Neocaridina. Caridina without RO is gambling.
-
Step 2
One species, one tank
A 10–20 gal heavily planted tank with moss is enough. Mixing Neo + Caridina fights both parameter targets.
-
Step 3
Remineralize on purpose
Neo: a GH+ shrimp mineral if tap is very soft. Caridina: a bee-specific GH/KH product on RO. Do not use random garden lime.
-
Step 4
Skip copper and fish that hunt
No copper algaecides. Bettas, pea puffers, and large tetras eat shrimp. Puffer care: pea puffer.
-
Step 5
Feed biofilm first, pellets second
Moss, leaf litter, and light biofilm beat constant protein wafers. Indian almond leaves help.
Common problems
Caridina die after a 20% tap change
Why: KH/pH swing.
Fix: RO only. Remineralize in a mixing jug. Drip acclimate.
Neo colors fade, numbers drop
Why: Predators or GH crash / copper.
Fix: Check tank mates and fertilizer labels.
Berried females, no shrimplets
Why: Fish eating babies, or no moss.
Fix: Add moss; remove hunters; keep adults well fed.
White ring of death on molt
Why: Mineral imbalance (classic Caridina).
Fix: Stabilize GH; add leaves; stop chasing pH daily.

FAQ
Can I keep both in one tank if I “aim for the middle”?
Middle water is usually bad for Caridina and only OK-ish for Neo. Use two tanks.
Is bottled “shrimp water” enough for Caridina?
Only if TDS/GH match the line you bought. Measure; do not trust the label alone.
Do they hybridize?
Neo × Caridina generally do not produce useful offspring, but you still wreck water targets.
Which is better for a first planted tank?
Neocaridina. Every time.
Can I use tap for Caridina if it is already soft?
Sometimes. Test GH/KH/TDS for a month. One municipal change can wipe a colony.
Amano vs cherry?
Amano eat more algae, do not breed in FW, and stay larger. Different job.
