The red cherry shrimp (Neocaridina davidi) is a petite, vibrantly coloured freshwater crustacean that has become a favourite among aquarium hobbyists for its dazzling ruby hue, hardiness, and prolific breeding. Native to the streams and rice paddies of Taiwan, these shrimp thrive in well‑filtered tanks with stable parameters—pH 6.5–7.5, a temperature range of 20–26 °C (68–78 °F) and plenty of live or artificial plants that provide both grazing surfaces and refuge from predatory fish.

Their omnivorous diet consists of biofilm, algae, detritus, and specially formulated shrimp pellets, which not only keep them healthy but also help maintain water quality by cleaning excess nutrients. Social by nature, red cherries do best in groups of at least ten, where they display gentle, inquisitive behaviour and engage in fascinating moulting rituals that reveal their translucent exoskeletons. Because of their rapid life cycle—maturing in 2–3 months and producing dozens of offspring each batch—these shrimp are an excellent entry point for beginners eager to observe the rewarding cycle of growth, colouration changes, and the delicate balance of a thriving micro‑ecosystem.

🦐 Red Cherry Shrimp

Red Cherry Shrimp are one of the most popular freshwater aquarium shrimp in the world. They’re colourful, hardy, and beginner-friendly, which makes them perfect for small planted tanks.

🔎 Basic Information

Scientific name: Neocaridina davidi
Origin: Taiwan
Size: 1–1.5 inches (2.5–4 cm)
Lifespan: 1–2 years
Temperament: Peaceful
Difficulty: Easy

🌈 Appearance

Bright red colouration (males are usually lighter, females darker and more solid red).
Females are larger and may show a “saddle” (eggs developing behind the head).
Colour intensity depends on genetics, diet, and tank conditions.

🏠 Tank Requirements

Tank size: 5 gallons (20L) minimum
Temperature: 68–78°F (20–26°C)
pH: 6.5–7.5
Water hardness: Moderate (they need minerals for moulting)
Plants & moss: Highly recommended (Java moss is ideal)

They love hiding places like driftwood, moss, and shrimp caves.

🍽️ Diet

Algae and biofilm (their natural food)
Shrimp pellets
Blanched vegetables (zucchini, spinach)
Occasional protein treats

Avoid overfeeding — small amounts once per day is enough.

🐣 Breeding

Red Cherry Shrimp breed easily in stable conditions.

Females carry 20–30 eggs under their abdomen.
Eggs hatch in about 2–3 weeks.
Babies are tiny versions of adults (no larval stage).

No special setup is needed if the tank is safe and stable.

⚠️ Tank Mates

Best kept:

In shrimp-only tanks
With small peaceful fish (like nano rasboras)

Avoid:

Large or aggressive fish (they may eat shrimp)
