Blue Velvet Shrimp Care Guide: What I Know From Keeping Cherry Shrimp

Published: April 21, 2026

Blue velvet shrimp are one of the most visually striking invertebrates you can add to a freshwater aquarium — a deep, powdery blue that seems to glow under the right lighting. But here’s something most care guides gloss over: they’re exactly the same species as red cherry shrimp. Neocaridina davidi, through selective breeding for a different pigmentation. Every observation I’ve made keeping cherry shrimp applies directly here.

That’s worth knowing, because it simplifies everything. If you’ve kept cherry shrimp successfully, you already know how to keep blue velvet shrimp. And if you’re new to shrimp keeping, this is an excellent starting point — Neocaridina davidi in any color form is one of the most beginner-friendly shrimp in the hobby.

Key Takeaways

• Blue velvet shrimp are Neocaridina davidi — the exact same species as cherry shrimp, just a different color morph through selective breeding
• They are beginner-friendly: hardy, easy to breed, and tolerant of a wide parameter range
• Do not mix with other Neocaridina color varieties — offspring will revert to wild-type brown
• Keep in groups of 10+ for natural behavior and visible colony activity
• Neocaridina (blue velvet, cherry) and Caridina (crystal red shrimp, bee shrimp) are different genera with different water requirements — don’t confuse them

The blue velvet shrimp is a captive-bred color morph of Neocaridina davidi, the same base species as red cherry shrimp, orange pumpkin shrimp, yellow neon shrimp, and a dozen other hobby variants. The original wild-type is a drab brownish-green from Taiwan’s freshwater streams; selective breeding over many generations isolated the blue coloration seen in blue velvet and blue dream varieties.

The “velvet” name refers to the soft, translucent quality of their blue color — less opaque than the solid blue of some higher-grade variants, more of a powdery, diffused effect that looks spectacular against a dark substrate in a heavily planted tank.

Blue Velvet vs. Cherry Shrimp vs. Crystal Red Shrimp

This is the most important distinction to understand before buying shrimp:

Shrimp	Species	Genus	Care Level	Water Type	Can They Mix?
Blue Velvet Shrimp	N. davidi	Neocaridina	Beginner	Hard, alkaline OK	Not with other Neocaridina colors
Red Cherry Shrimp	N. davidi	Neocaridina	Beginner	Hard, alkaline OK	Not with other Neocaridina colors
Crystal Red Shrimp	C. cantonensis	Caridina	Advanced	Soft, acidic only	Not with Neocaridina

Blue velvet shrimp and cherry shrimp are the same species and can interbreed. If you mix them, offspring will typically revert toward the wild-type brown coloration as the blue and red pigmentation genes don’t combine cleanly. To maintain the blue velvet color line, keep them isolated from all other Neocaridina varieties.

Crystal red shrimp (CRS) are an entirely different genus — Caridina. They require soft, acidic, remineralized RO water and are considerably more demanding. Don’t assume care guides for one apply to the other.

Mark’s Experience: Keeping Neocaridina davidi

I haven’t kept blue velvet shrimp specifically, but I’ve kept cherry shrimp — the same species — and everything I’ve observed translates directly. I’m being transparent about that distinction because it matters for honesty, but the biology, behavior, and care requirements are identical. Color is the only real difference.

The single biggest factor I’ve found for Neocaridina success: don’t rush the tank. New tanks stress these shrimp. I wait until a tank has been running for at least 6–8 weeks with stable parameters before adding shrimp. Cycling is not enough — you want a genuine, settled biological community, including biofilm on surfaces. Shrimp graze on biofilm constantly; a mature tank provides it naturally.

Second most important: colony size. People buy 5–6 shrimp and wonder why they rarely see them. With 10–15 shrimp you start seeing real activity. With 20+ the tank comes alive — shrimp grazing, foraging, occasional chasing during breeding behavior. You also buffer yourself against losses during acclimation, which are common even in healthy setups.

On feeding: I’ve found Neocaridina genuinely thrive on very little supplemental food in a planted, matured tank. Blanched vegetables once or twice a week (zucchini, spinach) plus biofilm grazing covers most of their nutritional needs. Overfeeding is a bigger risk than underfeeding — excess food spikes ammonia in a shrimp tank fast.

Tank Setup

Tank Size

A 5-gallon minimum is workable, but I’d recommend a 10-gallon for a first shrimp tank. More water volume means more stable parameters, and stability is everything with shrimp. A parameter swing that a fish might shrug off can wipe out a shrimp colony.

Substrate

Dark-colored fine substrate (black sand or dark gravel) does two things: it enhances the blue velvet’s coloration by contrast, and it supports beneficial bacteria. Avoid sharp substrates that can injure shrimp as they graze. Active aquasoils (like ADA Amazonia) work but buffer toward a lower pH — fine for most Neocaridina, but check your target parameters.

Filtration

A sponge filter is the standard recommendation for shrimp tanks — it provides gentle flow, surface area for biofilm, and no risk of sucking up shrimplets. If you use a hang-on-back or canister filter, cover the intake with a fine sponge prefilter. Baby shrimp (shrimplets) are tiny and will be pulled into any unguarded intake.

Plants and Decor

Heavy planting is strongly recommended. Java moss, Christmas moss, Anubias, and Java fern all work well. Moss in particular is critical — shrimplets hide in it during their vulnerable early days, and adults constantly graze the surface. Dense planting also buffers water chemistry and provides natural cover that keeps shrimp confident and visible.

Water Parameters

Parameter	Range	Optimal
Temperature	68–80°F (20–27°C)	72–76°F
pH	6.5–8.0	6.8–7.5
GH (General Hardness)	4–14 dGH	6–10 dGH
KH (Carbonate Hardness)	1–8	2–4
TDS	150–300	200–250
Ammonia	0 ppm	0 ppm
Nitrite	0 ppm	0 ppm
Nitrate	<20 ppm	<10 ppm

Unlike Caridina shrimp, Neocaridina davidi is forgiving across a wide parameter range. Most tap water that has been properly conditioned and aged will work. What matters more than hitting exact numbers is consistency — gradual changes shrimp can handle, sudden swings they cannot.

Feeding

Blue velvet shrimp are omnivores and opportunistic grazers. In a planted, mature tank they’ll spend most of their day grazing biofilm, algae, and decaying plant matter. Supplemental feeding 2–3 times per week is sufficient.

Good food options:

• Blanched vegetables: zucchini, spinach, cucumber (remove after 12–24 hours)
• Shrimp-specific pellets or wafers (Hikari Shrimp Cuisine, Repashy Soilent Green)
• Snowflake food (dried soybean husks — feeds slowly, won’t foul water)
• Occasional protein: small amounts of blanched egg yolk or frozen baby brine shrimp

Feed sparingly. In a planted tank, biofilm provides most nutritional needs. Uneaten food left in the tank is the leading cause of parameter spikes in shrimp setups.

Breeding

Blue velvet shrimp breed readily in a well-established tank with stable parameters. You don’t need to do anything special to trigger breeding — just maintain good conditions.

Females carry eggs under their tail (the “saddle” eggs visible through the body before fertilization, then the clutch of 20–30 eggs visible beneath the abdomen for 3–4 weeks). Shrimplets are born as fully-formed miniature adults — no larval stage. They’re immediately self-sufficient but extremely small and vulnerable.

Critical for breeding success:

• Cover all filter intakes with a sponge — shrimplets will be sucked up by unguarded intakes
• Provide Java moss or similar fine-leafed cover for shrimplets to hide in
• Keep other Neocaridina color varieties out — interbreeding will revert offspring to wild-type brown
• Breeding slows above 78°F and accelerates around 72–76°F

Tank Mates

Blue velvet shrimp are peaceful and easy to house with the right companions. The main risk: predation. Anything with a mouth large enough to eat a shrimp will try to eat a shrimp.

Good tank mates:

• Otocinclus catfish — peaceful algae eaters that won’t bother shrimp
• Small corydoras (pygmy corys, habrosus) — bottom dwellers that ignore shrimp
• Snails (nerite, mystery, ramshorn) — peaceful cleanup crew
• Small nano fish like chili rasboras or exclamation point rasboras — too small to eat adult shrimp

Avoid:

• Most bettas — they will eat shrimp
• Cichlids of any kind
• Gouramis larger than sparkling/pygmy size
• Goldfish — will eat shrimp
• Other Neocaridina color morphs — not a danger, but will interbreed and ruin the color line

FAQ

Are blue velvet shrimp the same as cherry shrimp?

Yes — they’re both Neocaridina davidi, the exact same species. Blue velvet shrimp are a selectively bred color morph just like red cherry shrimp, orange pumpkin shrimp, or yellow neon shrimp. All care requirements are identical; only color differs.

Can I keep blue velvet shrimp with cherry shrimp?

Physically yes, but not recommended if you want to maintain blue velvet coloration. They’ll interbreed, and offspring will revert toward wild-type brown over several generations. Keep each Neocaridina color morph in a separate tank.

Are blue velvet shrimp beginner-friendly?

Yes — Neocaridina davidi in any color form is one of the most beginner-friendly shrimp available. They tolerate a wider parameter range than Caridina shrimp and don’t require special water preparation like RO remineralization.

How many blue velvet shrimp should I start with?

Aim for at least 10–15 to establish a breeding colony. This gives you buffer for acclimation losses and enough individuals to see natural colony behavior. A breeding colony of 20+ is where you really see shrimp activity pick up.

How long until blue velvet shrimp breed?

In good conditions (stable parameters, mature tank, temperatures around 72–76°F), females can carry eggs within a few weeks of introduction. The eggs take 3–4 weeks to hatch. Once a colony is established, breeding is essentially continuous under good conditions.

Final Thoughts

Blue velvet shrimp are an excellent choice whether you’re new to invertebrate keeping or adding a splash of color to an existing planted tank. Their hardiness as Neocaridina davidi makes them forgiving for beginners, and their striking blue coloration makes them genuinely rewarding to keep.

The keys to success are simple: a mature, stable tank; proper filtration coverage for shrimplets; a large enough colony to see real activity; and isolation from other Neocaridina color morphs if you want to maintain the blue color line. Get those right and blue velvet shrimp are one of the lowest-maintenance, highest-reward additions you can make to a freshwater setup.
