The Cherry Shrimp is scientifically known as Neocaridina davidi.

Cherry shrimp are small freshwater dwarf shrimp loved for their bright red coloration and algae-cleaning abilities. Selective breeding has produced vibrant solid reds ranging from translucent pink to deep fire-engine red. Adults typically grow to about 1–1.5 inches (2.5–4 cm).

They are peaceful, hardy, and perfect for planted aquariums and nano tanks.

Care Instructions

Tank Size

• Minimum 5 gallons

• Best kept in groups of 10 or more

• Larger colonies feel safer and breed more readily

Water Parameters

• Temperature: 68–78°F (20–26°C)

• pH: 6.5–7.8

• Moderate hardness preferred (calcium helps shell health)

• Stable water is more important than exact numbers

They are beginner-friendly but sensitive to sudden parameter swings.

Tank Setup

• Heavily planted tank recommended

• Moss (like Java moss) is excellent for hiding and grazing

• Sponge filter preferred (shrimp-safe)

• Avoid copper (toxic to shrimp)

Provide plenty of biofilm surfaces — shrimp constantly graze.

What Do Cherry Shrimp Eat?

Cherry shrimp are omnivorous scavengers.

Natural Diet

• Algae

• Biofilm

• Decaying plant matter

Supplemental Foods

• Shrimp-specific pellets

• Blanched vegetables (zucchini, spinach, cucumber)

• Algae wafers

• Occasional protein treats (bloodworms, brine shrimp)

Feed small amounts once daily — they need less than most people think.

Fun Facts

• They help clean tanks by eating algae and leftover food.

• Their red color deepens with diet and dark substrate.

• Females are usually larger and more brightly colored than males.

• They molt regularly to grow — you may find empty shells in the tank.

• They are one of the most popular freshwater shrimp in the aquarium hobby worldwide.
