Quick answer: Cherry shrimp breed readily in a stable, mature, well-fed tank with no special intervention. Keep your parameters steady, start with a colony of at least 10, give them Java moss and biofilm to graze on, and they multiply on their own. To keep the line bright, grade your shrimp and cull the lower-color individuals so weak genetics don’t drag the colony back toward wild-type.
If you’ve got a planted tank and a love for inverts, Cherry Shrimp (Neocaridina davidi) are one of the easiest and most rewarding species to breed. The real challenge? Building a stable colony and improving color over time. This guide covers both.

Best Breeding Tank Setup
- Tank size: 5–10 gallons minimum (20 gallons ideal for a growing colony)
- Filter: Sponge filter or gentle HOB with guard
- Substrate: Inert or buffered (if breeding for color)
- Plants: Java moss, Subwassertang, floating plants (hiding spaces)
- Temp: 72–78°F (avoid heat spikes)
- pH: 6.8–7.5 ideal for color and health
- Water changes: 10–20% weekly (stable parameters are key)
Don’t use: Copper-based medications or fertilizers—these will wipe out shrimp instantly.
How Cherry Shrimp Breed
Once mature, female Cherry Shrimp will “saddle” (develop visible eggs under the shell) and become berried (eggs carried underneath). Males will detect pheromones and swim frantically to mate.
- Gestation: ~30 days before hatching
- Fry count: 20–30 per female (more if water is stable)
- They hatch fully formed: No larval stage—no intervention needed
Pro Tip: Stable parameters, consistent food, and minimal stress = constant breeding.
Caring for Shrimplets (Baby Shrimp)
- Don’t vacuum too deep—baby shrimp hide in substrate and moss
- Feed powdered foods (like Bacter AE or shrimp snow) for biofilm growth
- Leave algae on surfaces—shrimplets graze constantly
- Keep tank covered to prevent evaporation and sudden swings
No need to move babies—unlike fish, Cherry Shrimp won’t eat their young.
Color Grading 101: How to Sort Shrimp by Quality
Cherry Shrimp are graded by color depth, opacity, and uniformity. Breeding without culling or selection results in a “muddy” colony over time.
- Standard Cherry: Translucent red, often with clear patches
- Sakura: Brighter red with more body coverage
- Fire Red: Deep solid red, legs often colored too
- Painted Fire Red: Solid, opaque red across entire body
How to grade: Use a small acrylic photo box or cup, place it against white background, and examine under good lighting. Keep top-grade breeders in a separate tank if possible.
Breeding Tips, Tricks & Genetics
- Only breed high-grade shrimp together to maintain color
- Cull muddy or clear individuals (rehome or use in display tank)
- Feed variety: blanched spinach, shrimp pellets, biofilm boosters
- Don’t overcrowd—too many shrimp = stunted growth and faded colors
- Use remineralized RO water if your tap is inconsistent or high in copper
Common Mistakes to Avoid
- Using untreated tap water with copper
- Mixing too many Neocaridina colors—leads to wild-type offspring
- Sudden temperature changes from water changes
- Not testing TDS or pH regularly—consistency matters
- Skipping grading—colors will fade generation over generation
Final Thoughts
Cherry Shrimp are easy to breed but tough to master. Want a beautiful, deep red colony that turns heads? It’s all about the setup, consistency, and careful selection over time. Whether you’re breeding for fun, profit, or aquascaping flair—this is a species worth learning well.

Frequently asked questions
How do I breed cherry shrimp?
Set up a 5 to 10 gallon tank (20 is better for a growing colony) with a sponge filter, Java moss, and stable water. Add a colony of at least 10 to 15 shrimp so you get a mix of males and females, then feed lightly and keep parameters consistent. Mature females will saddle, become berried, and breed on their own. Never use copper-based medications or fertilizers, since copper wipes out shrimp fast.
How long until cherry shrimp start breeding?
Cherry shrimp reach breeding age at roughly 3 to 4 months old. Once a female is mature she saddles, mates, and carries the eggs for about 30 days before they hatch. Each female releases 20 to 30 fully formed shrimplets per batch, and a stable colony breeds almost continuously after that.
What water parameters do cherry shrimp need?
Aim for a temp of 72 to 78 F, pH 6.8 to 7.5, GH around 6 to 8, KH 1 to 4, and TDS in the 150 to 250 range. Stability matters more than hitting exact numbers, so keep water changes to 10 to 20 percent weekly to avoid swings. Use remineralized RO water if your tap is inconsistent or carries copper.
How do I get higher color grades?
Color grade goes from Standard Cherry (translucent red with clear patches) up to Sakura, Fire Red, and Painted Fire Red (solid opaque red over the whole body). Only breed your deepest, most opaque shrimp together and cull or rehome the muddy and clear ones every generation. Examine them in a small acrylic box against a white background under good light so you can sort accurately.
Do I need to separate the baby shrimp?
No. Cherry shrimp hatch fully formed with no larval stage, and the adults will not eat their young, so the babies stay in the main tank. Don’t vacuum deep into substrate or moss where they hide, and feed powdered foods like Bacter AE or shrimp snow to grow the biofilm they graze on. Keep the tank covered to prevent evaporation and sudden swings.
Why aren’t my shrimp breeding?
The usual cause is unstable water or copper exposure from untreated tap, fertilizers, or medications. Check that your colony is large enough (10-plus) and mature (3 to 4 months), and confirm temp, pH, and TDS are holding steady instead of swinging with each water change. Overcrowding also stunts growth and stresses shrimp, so thin the colony if it’s packed and keep feeding consistent.
