Cherry Shrimp Colour Grading Guide: From Lowest to Painted Fire Red

Walk into any aquarium shop in Singapore and you will find cherry shrimp labelled everything from “sakura” to “fire red” — but what do these grades actually mean? This cherry shrimp colour grading guide from Gensou Aquascaping at 5 Everton Park, Singapore, explains the recognised colour tiers of Neocaridina davidi var. red, from the palest wild-type translucence to the deepest Painted Fire Red. Understanding the grading system helps you buy smarter, breed selectively, and appreciate the genetics behind these tiny crustaceans.

How Colour Grading Works

Cherry shrimp colour grades describe the density and coverage of red pigmentation on the body. Grading is not an exact science — there is no international standard — but the hobby has broadly settled on a hierarchy that most breeders and sellers recognise. Each grade represents a step up in colour intensity, opacity, and consistency across the body and legs. Higher grades command higher prices because they require generations of selective breeding to stabilise.

Regular Cherry Grade

The base grade features a mostly translucent body with scattered patches of light red or pink. Legs and swimmerets are typically clear. Males at this grade are often nearly invisible in a planted tank, while females show a faint reddish wash, particularly along the saddle and back. Regular-grade cherries sell for $0.50-1.00 each in Singapore and are ideal for beginners who want a self-sustaining colony without worrying about selective culling.

Sakura Grade

Sakura shrimp show a more complete red coverage — roughly 60-80% of the body is coloured, though some clear patches remain, especially on the legs and lower abdomen. Females are noticeably redder than males. This is the most commonly available grade at local shops like those along Serangoon North Avenue 1, typically priced at $1-2 each. Sakura colonies produce a mix of offspring, with some trending higher and some lower, making them a practical starting point for selective breeding.

Fire Red Grade

Fire Red shrimp display solid red colouration across the entire body, including the legs. Very little translucency remains. Even males, which are smaller and naturally lighter, show strong red coverage. The saddle of egg-bearing females may appear slightly darker but does not break the overall colour consistency. Expect to pay $2-4 per shrimp locally. Maintaining this grade requires periodic culling — removing paler individuals from the breeding colony to prevent regression.

Painted Fire Red Grade

The highest standard grade, Painted Fire Red shrimp are deeply opaque red with zero translucency. The colour is so dense that internal organs are invisible, and even the underbelly and antennae carry pigment. These shrimp stand out dramatically against green plants and dark substrates. Pricing in Singapore ranges from $4-8 each, with particularly vivid specimens fetching more through hobbyist networks on Carousell. Breeding Painted Fire Red colonies true-to-grade demands strict culling and stable water conditions.

Factors That Affect Colour Expression

Genetics determines the ceiling, but environment influences how much colour a shrimp actually displays. Dark substrates enhance pigmentation — shrimp on white sand will appear paler than genetically identical siblings on black soil. Diet plays a role too; foods rich in astaxanthin and spirulina boost red tones. Water parameters matter less than stability, though a pH of 6.5-7.5, GH 4-8, and temperature of 22-26°C suit Neocaridina well. Singapore’s tap water, once dechlorinated, falls within acceptable range for cherry shrimp without significant adjustment.

Selective Breeding Tips

Start with the highest grade you can afford and maintain a colony of at least 20-30 individuals. Every four to six weeks, remove the palest shrimp to a separate “cull tank” — these make excellent algae cleaners in other aquariums. Introduce fresh bloodlines every six months to avoid inbreeding depression, which manifests as reduced fertility and weaker colour. Track your colony’s progress photographically; improvements across generations are subtle but measurable. Some breeders in Singapore run multiple colour lines simultaneously, which is feasible even in small HDB setups using 10-20 litre nano tanks.

Choosing the Right Grade for You

Not everyone needs Painted Fire Red shrimp. Regular and sakura grades are hardier, reproduce freely, and cost a fraction of the price. Higher grades reward dedicated breeders who enjoy the selective process. Whatever your goals, this cherry shrimp colour grading guide gives you the vocabulary to shop confidently and breed intentionally. Gensou Aquascaping draws on over 20 years of experience to help Singapore hobbyists get the most from their shrimp-keeping journey.
