Neocaridina Shrimp Care Guide: Water, Diet & Breeding
Neocaridina shrimp (Neocaridina davidi) are the most beginner-friendly freshwater invertebrate in the hobby — hardy, colorful, endlessly entertaining, and they breed like clockwork once you get their water right. A thriving shrimp colony adds movement and color to a planted tank in ways no fish can, and they'll clean your tank while they're at it.
At Tropical Treasures Wyo in Cheyenne, Wyoming, we breed and ship Neocaridina in nearly every color morph — cherry, blue dream, yellow, snowball, bloody mary, and more. This guide is everything we've learned keeping them in our own tanks and what we tell customers who want to start a shrimp colony of their own.
Quick Facts
- Scientific name: Neocaridina davidi
- Common names: Cherry shrimp, Blue Dream, Yellow shrimp, Snowball, Neo shrimp
- Origin: Taiwan (originally), now tank-bred worldwide
- Adult size: 1–1.5 inches (2.5–4 cm)
- Lifespan: 1–2 years
- Temperament: Peaceful, social, best kept in colonies
- Care level: Easy — the best shrimp for beginners
- Minimum tank size: 5 gallons (10 gallons for a real colony)
Why Neocaridina Are the Best Beginner Shrimp
Unlike their Caridina cousins (crystal red, blue bolt, tiger shrimp), Neocaridina thrive in neutral-to-hard tap water, don't need buffering substrate, and tolerate temperature swings that would kill more sensitive species. If you can keep guppies alive, you can keep Neocaridina shrimp.
They also come in more colors than any other freshwater shrimp:
- Reds: Red Cherry, Fire Red, Red Sakura, Bloody Mary, Red Rili
- Blues: Blue Dream, Blue Diamond, Blue Turquoise, Blue Jelly, Blue Cherry, Blue Carbon Rili
- Yellows & oranges: Yellow Goldenback, Yellow Rili, Orange Sakura, Orange Sunkist, Pumpkin, Neon Orange, Melon
- Greens, whites & blacks: Green Jade, Snowball, Black Rose
Important rule: all Neocaridina color morphs are the same species and will interbreed. Mixing colors in one tank produces muddy brown/clear offspring within a few generations. Keep each color in its own tank if you want to preserve the colors.
Tank Setup
Minimum tank size
- 5 gallons: minimum for a small starter colony (10–20 shrimp)
- 10 gallons: ideal first shrimp tank — more water volume = more stable parameters
- 20+ gallons: for serious breeding colonies or shrimp-and-nano-fish community tanks
Substrate
Neocaridina are flexible. You can keep them on:
- Inert gravel or sand — cheapest, keeps your tap water pH intact (best for Neos)
- Active planted substrate like Fluval Stratum — great for plants but will drop pH; fine for Neos, essential for Caridina
Filtration
Use a sponge filter — full stop. HOB and canister intakes suck in baby shrimp by the hundreds. A sponge filter provides gentle flow, massive biological filtration, and doubles as a grazing surface covered in biofilm. If you must use an HOB, cover the intake with a pre-filter sponge.
More detail in our best sponge filters for shrimp breeding tanks guide and our full aquarium filtration guide.
Plants and decor
Shrimp tanks live and die on plants and biofilm. Add:
- Java moss or Christmas moss — the single best shrimp plant; shrimplets hide in it and graze on it 24/7
- Anubias and java fern — low-light, low-maintenance, provide grazing surfaces
- Floating plants for cover and to mop up nitrates
- Indian almond (catappa) leaves — release tannins, antibacterial, and shrimp graze on the decomposing biofilm. A shrimp tank staple.
- Shrimp caves — molting refuges where shrimp hide when vulnerable

Water Parameters
| Parameter | Ideal Range | Notes |
|---|---|---|
| Temperature | 68–78°F (20–25°C) | 72–74°F is sweet spot |
| pH | 6.8–7.8 | Neutral to slightly alkaline |
| GH | 6–12 dGH | Critical — too soft causes molting problems |
| KH | 2–8 dKH | Provides pH stability |
| TDS | 150–300 ppm | Most tap water falls here naturally |
| Ammonia / Nitrite | 0 ppm | Non-negotiable |
| Nitrate | Under 20 ppm | Shrimp are more sensitive than fish |
The most common mistake: using RO water or super-soft water without remineralizing. Neocaridina need calcium and minerals to molt — soft water causes failed molts and colony deaths. If your tap water is very soft, add a remineralizer like Seachem Equilibrium or a calcium supplement like Kat's Aquatics Calcium Nutrition. Our Cheyenne tap water is perfect for Neos as-is — if you're local, bring in a sample for free water testing.
For a full breakdown, see our shrimp water parameters guide.
Diet & Feeding
Neocaridina are omnivorous scavengers. In a mature tank they get most of their food from biofilm and algae — the almost-invisible microbial layer covering every surface. Supplement 2–3 times per week with small amounts of:
- High-quality shrimp pellets — Fluval Bug Bites Shrimp Formula or Liquid Gardens Shrimp Candy Sticks
- Blanched vegetables — zucchini, spinach, cucumber slices (boiled 2 minutes then cooled)
- Mineral/calcium supplement like Kat's Calcium & Protein supplement — helps molting and exoskeleton development
- Occasional protein treat — a pinch of bloodworm or brine shrimp once a week
Feeding rules:
- Feed an amount the colony finishes in 2–3 hours
- Remove any uneaten food to avoid ammonia spikes
- In a well-established tank, skip feeding entirely 1–2 days a week
- If you don't see shrimp swarming the food, you're overfeeding
More detail in our how often to feed your fish guide.
Tank Mates
Almost any fish will eat shrimplets if they can catch them. Adults are safer but still at risk with anything over 3 inches. For a pure colony, keep them shrimp-only. For a community tank, choose carefully.
Safe(ish) tank mates
- Chili rasboras — mouths too small to eat shrimplets
- Celestial pearl danios — gentle, slow, mostly ignore shrimp
- Otocinclus catfish — peaceful algae eaters
- Snails: nerites, mystery snails — totally shrimp-safe
- Amano shrimp — bigger cousin species, won't interbreed
Risky but possible
- Small tetras (neon, ember) — eat shrimplets but ignore adults
- Guppies and endlers — same story
- Corydoras — physically can't catch shrimp but will eat any stray eggs
Never keep with shrimp
- Bettas (will eat them all eventually)
- Any cichlid, including rams and apistos
- Angelfish, gouramis, puffers
- Loaches of any kind
- Any fish over 3 inches
Breeding Neocaridina Shrimp
You don't breed Neocaridina — they breed themselves. If the parameters are right, a starter group of 10 shrimp will become 100+ inside 6 months.
- Start with a mixed group of 10+ — ensures both sexes.
- Maintain stable parameters — instability halts breeding.
- Females "berry up" — carry yellow, green, or brown eggs under their tail for 25–30 days.
- Eggs hatch as fully formed miniature shrimp — no larval stage like saltwater shrimp.
- Provide moss and cover — shrimplets survive or die based on how much microfauna and hiding space they have.
- Don't vacuum substrate aggressively — you'll suck up babies.
Common Problems
Failed molts ("white ring of death")
A visible white line across the shrimp's body means a failed molt — almost always caused by soft water (low GH) or sudden parameter swings. Add a mineral supplement and slow down water changes. Our guide to shrimp molting problems walks through the causes and fixes in detail.
Colony stops breeding
Usually means a parameter shift, new water source, overfeeding, or too-high nitrate. Test your water and do small, frequent water changes (10% weekly) instead of big ones.
Shrimp losing color
Stress, poor diet, or the morph genetically reverting. Feed a high-quality shrimp food and only mix shrimp of the same color. Remove off-colored "wild" shrimp from breeding tanks.
Copper poisoning
Neocaridina are extremely sensitive to copper. Never use fish medications containing copper (including many ich treatments). Check your tap water — old copper pipes can leach enough copper to wipe out a colony.
Sudden die-off after water change
Chlorine/chloramine not neutralized, or a big swing in GH/KH/TDS. Always dose Seachem Prime and match temperature/parameters on water changes.
Tips for Long-Term Success
- Cycle the tank for at least 4–6 weeks before adding shrimp
- Let the tank mature — a dirty glass and algae-covered decor is good in a shrimp tank
- Drip acclimate new shrimp slowly over 1–2 hours
- Weekly 10% water changes — small and steady beats big
- Add a handful of Indian almond leaves to every tank
- Don't mix color morphs unless you want mutts
- Buy from a breeder, not a chain store — chain shrimp are often culled, pH-shocked, or exposed to copper
Frequently Asked Questions
How fast do Neocaridina shrimp breed?
Very fast under good conditions. A female can carry 20–30 eggs every 25–30 days. A group of 10 can become 100+ in six months.
Can Neocaridina shrimp live with fish?
Yes, with small peaceful fish like chili rasboras, ember tetras, or celestial pearl danios. Shrimplets will still be eaten — expect a controlled-growth colony rather than a population explosion.
Do Neocaridina shrimp need a heater?
Not always. They tolerate 68–78°F, so room-temperature tanks often work. But a heater prevents temperature swings, which cause more deaths than a steady cool temperature.
What's the easiest color morph for beginners?
Red cherry shrimp. They're the hardiest, cheapest, and easiest to see against plants and substrate. Bloody mary and fire red are more colorful variations.
Can I mix Neocaridina color morphs?
You can, but they'll interbreed and produce washed-out brown or clear offspring within a few generations. Keep each color in its own tank if you want to preserve the color.
How many Neocaridina shrimp should I start with?
At least 10 — ensures you get both males and females. Starting with fewer often results in a single-sex group and zero breeding.
Do Neocaridina and Caridina shrimp interbreed?
No. They are different genera and cannot crossbreed. You can keep them in the same tank, but they need different water parameters (Caridina prefer soft, acidic water), so most keepers choose one or the other.
How long do Neocaridina shrimp live?
About 1–2 years. A well-established colony self-renews indefinitely as long as breeding continues.
