Caridina vs Neocaridina: Which Shrimp Should You Keep?

The Genus Problem

Search this comparison and you’ll be told, repeatedly, that Neocaridina are the easy shrimp and Caridina are the hard ones. That shorthand is useful right up until it misleads you — because Caridina is a large, diverse genus, and the two Caridina species most Canadian keepers actually encounter sit at opposite ends of the difficulty range.

• Crystal red, crystal black, bee and tiger shrimp (Caridina cantonensis and relatives) are what people usually mean by “Caridina.” These are the soft-water specialists: narrower tolerances, more sensitivity to swings, and usually a purpose-built tank.
• Amano shrimp (Caridina multidentata) are also Caridina — and they are famously durable, tolerate a wide parameter range, and are one of the most recommended algae-eaters in the hobby.

So when you’re choosing, the genus name tells you less than the species does. What follows compares Neocaridina against bee-type Caridina, with Amano called out separately wherever it breaks the pattern.

Side-by-Side Comparison

Water Chemistry: The Real Divider

Almost every practical difference traces back to minerals. Neocaridina build and molt best with meaningful hardness — we raise ours around pH 6.8–7.4, GH 6–10, KH 2–6 (full detail in the Neocaridina care guide). In much of Canada, that describes tap water straight from the pipe.

Bee-type Caridina generally want the opposite: soft, acidic, low-mineral water with little to no carbonate hardness. Keepers usually build it deliberately — RO or RO/DI water remineralized to a target, over an active soil substrate that pulls pH down and, importantly, exhausts over time and eventually needs replacing. None of that is exotic, but it is a system to maintain rather than a tank to fill.

Amano break the rule again: they tolerate a broad range and generally do fine in the same water a Neocaridina colony enjoys.

Breeding Compared

Neocaridina and bee-type Caridina share the trait that makes dwarf shrimp so rewarding: direct development. Females carry eggs for weeks and release fully formed miniature shrimp — no larval stage, no separate rearing setup. Neocaridina simply do it in easier water, which is why colonies snowball for beginners (see the colony-method breeding guide).

Bee-type Caridina breed the same way, but the margin for error is narrower — stable soft water, mature tanks, and patience. Many keepers succeed; few succeed accidentally.

Amano are the exception in the whole comparison. Their larvae hatch tiny and require brackish or salt water to develop, then migrate back to fresh water. Reproducing that in a home aquarium is a deliberate, difficult project, which is why virtually every Amano sold is wild-caught or commercially raised rather than hobby-bred. If a shrimp in your tank is berried and nothing ever comes of it, and it’s an Amano, that’s expected — not a failure on your part.

Also worth knowing: Neocaridina and Caridina cannot interbreed. Within Neocaridina, colour lines cross freely and revert toward wild brown — which is why you keep one line per tank (see the cherry shrimp profile). Across genera, no such risk exists.

Can You Keep Them Together?

Physically, yes — they don’t fight, compete destructively, or hybridize. The problem is chemistry. Neocaridina want minerals; bee-type Caridina want them stripped out. A compromise tank in the middle typically leaves both species outside their best range, and the usual result is a colony that survives without ever really thriving or breeding well.

The practical answers most keepers land on:

• Pick one and build the tank around it — the most reliable path to a breeding colony.
• Run two tanks if you want both, each tuned to its species.
• Pair Neocaridina with Amano — the genuinely easy mixed-genus combination, since Amano thrive in Neo-friendly water. You get a colour colony plus serious algae control, and because Amano won’t reproduce, their numbers stay exactly where you set them.

Which Should You Buy?

• First shrimp ever? Neocaridina. Start with a wild-type colony if you want maximum forgiveness, or cherry shrimp for colour from day one.
• Want a breeding colony that compounds? Neocaridina, single colour line.
• Fighting algae in a planted tank? Amano shrimp — the strongest algae grazers of the three, with no population explosion to manage.
• Want a long-term keeper project and soft water available? Bee-type Caridina. We don’t raise them — our colonies are Neocaridina and Amano — so if that’s your direction, buy from a specialist breeder who can tell you the exact TDS and GH their stock was raised in, and match it.
• Hard tap water and no interest in RO? Neocaridina, comfortably.

Common Misconceptions

• “Caridina are always hard to keep.” Amano are Caridina and are beginner-friendly. Species matters, not genus.
• “Neocaridina and Caridina will crossbreed and ruin my line.” They can’t interbreed. Colour-line mixing within Neocaridina is the real reversion risk.
• “My Amano is berried, so babies are coming.” Amano larvae need brackish water to develop; berried females in freshwater tanks typically produce nothing.
• “Soft water is better for all shrimp.” Soft, mineral-poor water is a common cause of failed molts in Neocaridina.
• “Higher grade means hardier.” Grade describes appearance, not resilience — heavily selected lines are sometimes less robust than plainer stock.

FAQ

What is the difference between Caridina and Neocaridina shrimp?

They are separate genera of dwarf shrimp. Neocaridina generally prefer harder, neutral to alkaline water and are more forgiving; bee-type Caridina generally need soft, acidic, low-mineral water. Amano shrimp are a Caridina species that is an exception — hardy and tolerant of a wide range.

Can Caridina and Neocaridina live together?

They can coexist peacefully and cannot interbreed, but their ideal water parameters conflict, so one species is usually compromised. Neocaridina plus Amano is the easy mixed pairing.

Are Neocaridina easier than Caridina?

Compared with bee-type Caridina, yes — they tolerate a wider parameter range and often thrive in unmodified tap water. Compared with Amano, difficulty is similar.

Do Caridina and Neocaridina crossbreed?

No. Different genera do not hybridize. Colour lines within Neocaridina do cross, which is why single-line tanks are recommended.

Which shrimp is best for a beginner in Canada?

Neocaridina, in most cases — much Canadian tap water already suits them, and locally raised stock skips the chemistry shock of imported shrimp.
