Insights

Original analysis from the index's own dataset — daily snapshots of the complete public catalogs of the US shrimp vendors we track. Every figure recomputes from the latest data (currently through September 2, 2026); nothing is quoted from other sites.

The market, measured

• Do Aquarium Shrimp Prices Actually Move? We Measured.
  Nearly 12,000 listing-day observations across seven US vendors — and not one genuine repricing of a dwarf shrimp listing. What that means for buyers.
• Sale Tags vs. Real Price Drops: How to Read a Shrimp 'Discount'
  A sixth of in-stock shrimp listings display a markdown against a compare-at price. Our day-by-day tracking shows how those tags relate to actual repricings — and how differently vendors use them.
• Dwarf Shrimp Market Report — July 2026
  The index's first monthly report: repricing (or the total absence of it), stock churn, sale-tag patterns, and catalog composition across seven US shrimp vendors.
• What US Shrimp Vendors Actually Sell: The Most-Listed Morphs
  Listing counts are a live census of the online hobby: which morphs dominate shelves, the Neocaridina–Caridina split, and how much of a 'shrimp store' is actually shrimp.

Pricing studies

• The Bulk Discount, Measured: What Pack Size Does to Per-Shrimp Price
  Singles, 5-packs, 10+1s, 25-packs — the same shrimp at very different per-animal prices. We measured the pack-size curve across every listing we track.
• What a Shrimp Grade Is Actually Worth
  Cherry, Sakura, Fire Red, Painted Fire Red: the grade ladder is supposed to be a price ladder. Today's cross-vendor data says the steps are smaller — and less orderly — than the names suggest.
• The Caridina Premium: What Stepping Up from Neocaridina Costs
  Caridina keeping demands more of the keeper — and the market prices that in. We measured the gap between the two genera across every unit-priced listing.

Price guides

• What Cherry Shrimp Cost: The Red Neocaridina Family, Priced
  The hobby's default first shrimp, from plain cherry to Bloody Mary — current per-shrimp prices across US vendors, and where the red family's price lines actually sit.
• Blue Shrimp Prices: Dream, Velvet, Diamond, Jelly — and Blue Bolt
  Five names, two genera, and a price range that triples. What each blue line costs per shrimp today, and which 'blue' you're actually buying.
• Crystal Red and Crystal Black Shrimp Prices
  The classic entry into Caridina keeping, priced across five vendors — with the grade caveats that actually matter when comparing listings.
• The Collector Tier: Galaxy, Fancy Tiger, King Kong and Boa Prices
  Where dwarf shrimp prices climb past $10 an animal — current cross-vendor prices for the show and breeder lines, and why the spread is structural.
• Amano Shrimp Prices: The Hobby's Workhorse, Costed
  The most-listed shrimp on the index. What an Amano costs per animal, why sizes move the price, and how pack buying changes the math.
• Starting a Shrimp Colony: A Priced-Out Budget
  A realistic starter colony priced at today's actual market medians, not forum guesses — budget Neocaridina and step-up Caridina versions.
