Cherry Shrimp Care Guide: Neocaridina for Beginners

Published 3 June 2026

Cherry shrimp are the entry point to shrimp keeping for most hobbyists, and for good reason. They’re forgiving, colourful, actively useful (they graze algae and clean up detritus), breed readily in captivity, and look beautiful in a planted tank. Unlike some specialty shrimp that require pristine water and precise parameters, Neocaridina shrimp tolerate a wider range of conditions than almost any other dwarf shrimp.

This guide covers everything you need to set up, stock, and breed cherry shrimp successfully.

What are cherry shrimp?

Cherry shrimp (Neocaridina davidi) are freshwater dwarf shrimp native to Taiwan. In the wild they’re a drab olive-brown colour. Decades of selective breeding have produced numerous colour variants — the most common being the red “cherry shrimp” (various grades), as well as yellow, orange, blue, green, and black/white variants.

All are the same species and will interbreed if kept together, gradually reverting to wild-type colouration over generations. Keep colour variants separate if you want to maintain specific colours.

Size: 2–4cm (females are larger and more vibrantly coloured than males) Lifespan: 1–2 years typically

Water parameters

Neocaridina are among the most tolerant dwarf shrimp in the hobby. This makes them suitable for a wider range of tap water conditions than the more demanding Caridina species (Crystal Red Shrimp, Bee Shrimp).

The most critical parameters are ammonia (0 at all times), nitrite (0 at all times), and nitrate (as low as possible). Shrimp are significantly more sensitive to water quality than fish — a parameter that a fish tolerates may kill shrimp.

Most tap water in Australia, the US, UK, and Europe falls within Neocaridina’s acceptable range. Test your tap water; if pH is between 6.5 and 8.0 and the water isn’t extremely soft or very hard, it will likely work.

Tank requirements

Minimum tank size: 20L (5 gallons). Smaller is possible but parameters fluctuate too quickly for shrimp comfort.

Recommended: 30–40L for a colony of 20–30 shrimp.

Filtration

Sponge filters are the best choice for shrimp tanks. The gentle, air-powered flow doesn’t create current that exhausts shrimp, and crucially — juvenile shrimp (baby shrimp, or “shrimplets”) are tiny enough to be sucked into HOB filters and killed. A sponge filter eliminates this risk entirely.

If you want to use a HOB filter, cover the intake with a fine sponge pre-filter to prevent shrimp from being sucked in.

Substrate

Aquasoil is ideal for Neocaridina shrimp. It buffers pH into the slightly acidic range they prefer, provides a surface for biofilm growth (a major food source for shrimp), and the dark colour shows off red and coloured shrimp beautifully.

Inert substrates (gravel, sand) work but require more attention to water chemistry.

Plants

Heavily planted tanks are better for shrimp. Dense plant growth provides:

• Biofilm on leaf surfaces — one of the shrimp’s primary food sources
• Cover for moulting shrimp (shrimp are vulnerable during and immediately after a moult)
• Hiding places for females carrying eggs and for shrimplets

Best shrimp tank plants: java moss, christmas moss, other mosses, java fern, anubias, bucephalandra. See our dedicated best plants for shrimp tanks guide.

Feeding

Shrimp are omnivorous scavengers. In a well-planted, established tank with biofilm and algae growth, shrimp can survive and breed without supplemental feeding. For a healthy, fast-growing colony:

Primary diet (in a planted tank):

• Biofilm on plant surfaces, hardscape, and substrate
• Algae (green algae, diatoms, soft algae)
• Decaying plant matter

Supplemental feeding (2–3x per week):

• Sinking shrimp pellets (Hikari Crab Cuisine, Glasgarten Bacter AE)
• Blanched vegetables: zucchini/courgette (extremely popular), spinach, cucumber
• Shrimp-specific foods: spirulina wafers, mineral-enriched foods

Don’t overfeed. Uneaten food decays rapidly and spikes ammonia. Remove any uneaten food after 2–4 hours. A small colony in a well-planted tank needs only a pea-sized amount of food per feeding.

Breeding cherry shrimp

Cherry shrimp breed readily in captivity — often without any intervention. If your parameters are stable, temperature is appropriate (22–25°C), and you have a mixed-sex group, breeding happens naturally.

Sexing shrimp

Females are larger, more vibrantly coloured, and have a curved underbelly. Males are smaller, often lighter in colour, and have a straighter underside.

To start a breeding colony, purchase a group of 10–15 mixed shrimp. Sellers typically include a mix of sexes.

The breeding process

1. A sexually mature female moults and releases pheromones into the water
2. Males detect the pheromones and swim frantically around the tank searching for the female — this “male frenzy” is a reliable sign that breeding is occurring
3. The female is fertilised within hours of moulting
4. The female develops eggs visible as a yellow-green “saddle” shape behind her head
5. The eggs are transferred to the underside of the female’s tail after fertilisation — she’s now “berried” (the eggs look like a cluster of tiny berries)
6. The female fans the eggs with her tail pleopods for 3–4 weeks until the eggs hatch
7. Shrimplets emerge as fully-formed miniature shrimp, approximately 1–2mm long

Don’t disturb a berried female. Stress can cause her to drop the eggs.

Caring for shrimplets

Shrimplets are tiny, translucent, and vulnerable. They graze on biofilm and need the same things as adult shrimp: clean water, no predators, and lots of surfaces to graze on.

Sponge filtration is critical at this stage — HOB intakes will kill shrimplets.

A mature, heavily planted tank with java moss is the ideal nursery. The moss provides countless surface areas for biofilm and hiding spots for small shrimp.

Population growth is fast — a starting colony of 15 can reach 100+ within a few months in good conditions.

Common problems

Shrimp dying after water changes

The most common cause: water change water that’s significantly different in temperature, pH, or chemistry from the tank. Always match the temperature of new water to the tank. Consider drip acclimation for water changes in shrimp tanks — slowly drip new water into the tank rather than pouring it in.

Shrimp dying in an established tank

• Check ammonia and nitrite first — 0 ppm mandatory
• Check for recent copper exposure. Copper is lethal to shrimp at very low concentrations. Some fertilisers, tap water additives, and fish medications contain copper. Check any product added to the tank.
• Check for predation if kept with fish

Failed to breed despite good parameters

• Confirm you have both males and females
• Temperature may be slightly low — try raising to 23–24°C
• The colony may be too small — fewer than 6–8 shrimp means fewer breeding opportunities
• A new colony often takes 4–8 weeks to settle before breeding begins

Colour fading over generations

Mixed colour variants revert to wild-type colouration over time. Separate colour variants or cull back to your desired colour morph by removing off-colour shrimp from the breeding population.

Frequently asked questions

Can cherry shrimp live with fish? Some fish coexist peacefully with shrimp; many eat them. The safest tank mates are small, peaceful species: otocinclus, small corydoras, ember tetras, chili rasboras. Bettas and most other fish with large mouths will eat shrimp, especially shrimplets. See our betta tank mates guide for more detail.

How many cherry shrimp should I start with? A minimum of 10–15. Fewer than this reduces genetic diversity and the number of breeding pairs. Start with 15–20 from a reputable source.

How long until cherry shrimp breed? In appropriate conditions, a new colony typically begins breeding within 4–8 weeks of introduction. Females can carry eggs as early as 4–6 months of age.

Do cherry shrimp need a heater? Neocaridina tolerate temperatures down to about 15°C and up to 28°C. In most temperate homes they don’t need a heater year-round, but temperature stability matters — avoid tanks near windows or heat sources that create fluctuations.
