Cherry Shrimp Care & Color Grades: A Complete Beginner's Guide

Cherry shrimp might be the most beginner-friendly invertebrate in the freshwater hobby. They're peaceful, endlessly entertaining, and once their tank is stable they breed themselves into a self-sustaining colony with almost no intervention. They also come in a rainbow of colors — from soft pinkish wild types to deep blood-red Bloody Marys and shimmering Blue Diamonds. Here's everything you need to know to keep them thriving, plus the full color-grade ladder.

What Is a Cherry Shrimp?

All "cherry shrimp" are Neocaridina davidi — a small (about 1 inch / 2.5 cm) peaceful freshwater shrimp originally from Taiwan. They live 1.5–2 years, eat biofilm and algae, and have been line-bred over decades into dozens of color morphs. Every Neocaridina color is the same species, which has two important consequences: they all need the same care, and they'll interbreed freely. Mix two colors and within a generation or two your colony reverts to muddy wild-type brown.

The Color Grade Ladder

Red cherry shrimp are graded by how solid and saturated their color is. The traditional red ladder goes like this:

  1. Wild Type — translucent brown/grey. The natural form.
  2. Cherry — patchy red with clear sections. The classic entry-level shrimp.
  3. Sakura — mostly red with a few clear patches. Brighter than standard cherry.
  4. Fire Red — completely red body, may still have clear legs.
  5. Painted Fire Red / Bloody Mary — solid deep red including legs and head. The top of the grade ladder.

Other color lines have their own grading conventions but follow the same logic: the more solid and saturated, the higher the grade.

Important: Only keep one color line per tank if you care about offspring color. Mixed colors interbreed and produce drab brown shrimp within 2–3 generations.

Tank Setup

Cherry shrimp are tiny and undemanding. A heavily planted, mature 5-gallon can support a colony of 20+ shrimp — though 10 gallons gives you more buffer and lets your colony grow faster.

  • Filter: A sponge filter is ideal. We recommend the Hikari Bacto-Surge Mini — gentle flow that won't suck up shrimplets. Hang-on-back filters need a pre-filter sponge.
  • Plants: Mosses, Anubias, Bucephalandra, and floating plants are shrimp heaven. They graze biofilm off every leaf. Browse aquarium plants.
  • Hardscape: Cholla wood and other cholla pieces are essential — they grow biofilm fast and shrimp graze on them constantly.
  • Substrate: Inert sand or gravel is fine for Neocaridina (unlike Caridina, which need active buffering substrate). Plant-friendly substrate is a bonus.
  • Lid: Required. Shrimp climb anything they can reach.

Water Parameters

Cherry shrimp are famously hardy as long as parameters stay stable. Aim for:

  • Temperature: 68–78°F (20–26°C). They breed faster at higher temps but live longer at lower ones.
  • pH: 6.5–8.0
  • GH (general hardness): 6–8 dGH — crucial for proper molting
  • KH (carbonate hardness): 2–6 dKH
  • TDS: 200–300 ppm
  • Ammonia & nitrite: 0 — non-negotiable
  • Nitrate: <20 ppm

Test weekly with the API Freshwater Master Test Kit. Never use copper-based medications, plant fertilizers, or treatments in a shrimp tank — copper is lethal to invertebrates.

Cycling Is Non-Negotiable

Shrimp are far more sensitive to ammonia and nitrite than most fish. Cycle your tank fully before adding shrimp — see our complete cycling guide. Use Seachem Prime as your dechlorinator and dose Seachem Stability daily during the cycle.

Acclimation

Shrimp are extremely sensitive to TDS and parameter swings. Drip acclimate slowly over 1–2 hours: float the bag to match temperature, then siphon tank water into a separate container at 1–2 drops per second. Once the container volume has roughly tripled, net (don't pour) the shrimp into your tank. See our quarantine guide if you're adding shrimp to an established tank with fish.

Diet

In a mature planted tank, shrimp will spend 90% of their time grazing biofilm — the green/brown film that coats every surface. Supplement with high-quality shrimp food 2–4 times a week:

Blanched veggies (zucchini, spinach, carrot) are also excellent. Feed only what the colony can finish in 2–3 hours — uneaten food fouls water and is the #1 cause of failed shrimp tanks. Browse the full shrimp food collection.

Molting and Mineral Supplements

Shrimp molt their exoskeleton every 3–6 weeks as they grow. A successful molt requires correct GH and adequate calcium. If you see incomplete molts (shrimp stuck in their old shell, the "white ring of death" around the back), your GH or calcium is off.

Supplement with:

Don't remove old molts — shrimp will eat them to reabsorb minerals for their next molt. The white empty shell on the substrate is a healthy sign, not a dead shrimp.

Breeding

If parameters are right and shrimp are fed and unstressed, they'll breed on their own. The process:

  1. Saddle: A female develops a yellow or green saddle-shaped mass behind her head — these are eggs maturing in the ovaries.
  2. Mating: After a female molts, males chase her frantically. Mating happens in seconds.
  3. Berried female: She carries 20–40 fertilized eggs under her tail (the "berry"), fanning them for 25–35 days.
  4. Hatch: Tiny fully-formed shrimplets (about 1–2 mm) emerge. No larval stage, no special food needed — they eat biofilm immediately.

The keys to a thriving colony: heavily planted tank, no large predator fish, stable water, and mosses or cholla for shrimplet hiding spots. A healthy 10-gallon colony can double every 2–3 months.

Tankmates

Cherry shrimp are best in a shrimp-only tank, but they can coexist with very small, peaceful fish:

  • Good: Otocinclus, Pygmy Corydoras, Chili Rasboras, Endlers (some), small Pencilfish
  • Risky: Most tetras (will eat shrimplets), Guppies (same), small loaches
  • No way: Bettas, gouramis, angelfish, anything that fits a shrimp in its mouth

Mosses, cholla, and dense plant cover are critical when keeping shrimp with fish — adults are usually safe, but shrimplets will be eaten.

Common Problems

Sudden die-off after a water change: TDS spike, copper from new tap water, or unrinsed product residue. Always test before adding new water.

Failed molts / "white ring of death": Low GH or calcium. Add a mineral supplement and check parameters.

No berried females: Tank too young, GH too low, parameters unstable, or too few shrimp (start with at least 10).

Hydra or planaria: Small white worms or stalked predators that eat shrimplets. No-Planaria (a snail-safe product) or manual removal — never use fenbendazole around shrimp.

Green water: Harmless — shrimp love it.

FAQ

Can I keep multiple colors together? Yes for the adults, no for breeding — offspring will revert to wild-type brown. Stick to one color per tank.

Do I need a heater? Optional — they thrive at room temp (68–75°F). A heater is helpful in cold rooms or for faster breeding.

How many shrimp should I start with? At least 10, ideally 15–20. Larger groups breed faster and tolerate occasional losses.

Can shrimp live with my betta? Some bettas ignore shrimp; many hunt them. Try at your own risk in a heavily planted tank.

Are shrimp hard? Once cycled and stable, they're one of the easiest livestock options. The hard part is patience during the 4–6 week cycle.

How fast do they breed? A well-fed colony in a stable tank can double every 2–3 months once they start. Expect zero progress for the first month or two, then exponential growth.

Ready to Start a Colony?

Cherry shrimp turn a planted nano tank into a constant micro-drama of grazing, molting, and tiny berried mothers. Browse our complete shrimp lineup, pair it with the right plants and filtration, and you'll have a self-sustaining colony in a few months.
