Buying your first Neocaridina shrimp is exciting — and a little overwhelming. Customers ask us two questions more than any other: How many should I start with? and What does the grade name mean? This guide answers both, grounded in what we actually carry.
Part 1 — Choosing Your Pack Size
Our Shrimp collection offers most species in 1, 5, 10, and 20-shrimp packs (Orange Sunkist also comes in a 40-pack). Here's how to think about which size fits your situation.
The 1-Shrimp Option — Dipping a Toe In
A single shrimp is great for one thing: testing compatibility with an existing tank before committing to a colony. It's also a low-risk way to try a color you've never kept. What it won't do is start a self-sustaining breeding group — for that, you need a mixed-sex group of at least 5–10.
The 5-Pack — Best for Nano Tanks (5–10 Gallons)
Five shrimp in a mature, heavily planted nano tank gives them room to establish territory, show natural grazing behavior, and — if you have a male-female mix — begin breeding. Population growth will be slow at first, which is actually ideal for smaller volumes where waste builds up quickly. If your tank is under 10 gallons, starting with 5 and letting the colony grow naturally is a sound approach.
The 10-Pack — The Sweet Spot for Most Beginners (10–20 Gallons)
A 10-pack gives you a meaningful starting colony: enough genetic diversity, a better shot at a balanced male-to-female ratio, and faster establishment. For a 10–20 gallon planted tank with stable water parameters, this is the pack size we most often recommend to first-time keepers. You'll typically see breeding activity within the first few weeks once the shrimp settle in.
The 20-Pack — For Larger Tanks or Serious Breeders (20–40 Gallons)
If your tank is 20 gallons or larger, or if your goal is building a breeding colony quickly, a 20-pack lets you hit a population density where the colony sustains and grows on its own. It's also useful if you want to add shrimp to multiple tanks from one order.
The 40-Pack — Maximum Head Start (Available for Orange Sunkist)
Currently available for our Orange Sunkist Shrimp, the 40-pack is for keepers who want to hit breeding density immediately or who are setting up a dedicated shrimp-only display tank of 40+ gallons. It's the most economical per-shrimp option we offer.
A Note on Tank Readiness
Pack size is only one variable. Neocaridina shrimp thrive in fully cycled tanks with stable parameters — ammonia and nitrite at zero, nitrates low, and pH between 7.0–7.8. More shrimp in an unstable tank isn't better; it's riskier. When in doubt, start smaller, stabilize your water, and add more shrimp once the first group is thriving.
Part 2 — Understanding Color and Grade Names
Neocaridina davidi (the species behind most of our shrimp) has been selectively bred into a wide range of colors. The names can be confusing because the hobby hasn't standardized them — but here's what the terms mean in the context of what we sell.
Cherry Shrimp
"Cherry" is the most common red Neocaridina color line. Our Cherry Shrimp display a solid red coloration across the body. Females are typically more deeply colored than males. "Cherry" does not imply a specific intensity grade in our store — all of our cherry shrimp are selectively sourced for good, consistent color.
Blue Dream and Blue Jelly
Both are blue color lines, but they have distinct appearances. Our Blue Dream Shrimp tend toward a rich, solid blue with good opacity. Our Blue Jelly Shrimp have a translucent quality — the blue appears almost glowing or jelly-like, especially under bright aquarium lighting. Both are Neocaridina; the difference is in the specific breeding line, not the species.
Orange Sunkist
"Sunkist" is the hobby name for a vivid orange Neocaridina line. Our Orange Sunkist Shrimp show a warm, saturated orange that makes them highly visible in planted tanks — especially against green or dark substrate. The name comes from the fruit, not a grading system.
Yellow RazorBack
Our Yellow RazorBack Shrimp have a distinctive yellow body with a darker stripe running along the back — hence "razorback." It's a purely descriptive name for this color pattern, not a grade designation.
What About Grade Terms Like "Painted Fire Red" or "Sakura"?
You may see terms like Sakura, Painted Fire Red, or Fire Red on other sites. These refer to intensity grades within the red/cherry line — essentially how deeply and fully colored the shrimp are. We keep our naming simple and tied to the color lines we actually stock, rather than layering grade labels that can vary by breeder. If you have questions about the coloration of a specific batch, feel free to reach out before ordering.
