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.
Published July 29, 2026 · figures recomputed from data through July 31, 2026 · by Shrimp Price Index
This is the first monthly report from the Shrimp Price Index, covering daily tracking from July 15, 2026 through July 31, 2026. The index reads the complete public catalogs of seven US shrimp vendors once a day and follows every individual dwarf shrimp listing from day to day.
July by the numbers
July's defining fact is total stillness: across 13,487 listing-day comparisons of individual shrimp listings, not a single price changed. Meanwhile listings went in or out of stock 48 times — the churn in this market is inventory, not price. US dwarf shrimp vendors publish a price and hold it. (Full analysis: Do aquarium shrimp prices actually move?)
For contrast: the 2026-07-23 portfolio price-movement audit found the same seven stores repriced their non-shrimp livestock (fish, snails) 89 times through July 23 — nearly all of it one vendor's two-day promotional wave on fish. The promotion machinery exists at these stores; it just wasn't pointed at shrimp.
The standing-sale landscape
A point-in-time reading from July 29: of 587 in-stock dwarf shrimp listings across the seven vendors, 99 (17%) displayed a compare-at price above the asking price — 95 of them at a single vendor, Shrimpy Business, where that's 59% of the in-stock shrimp catalog. Four of the seven vendors used no sale tags on shrimp at all. None of the 99 tagged listings had changed price at any point in our tracking window: the tags are standing merchandising, not July price cuts. How to read that as a buyer: Sale tags vs. real price drops.
Catalog composition, as of July 29
The seven vendors carried 862 priced dwarf shrimp listings: 502 Neocaridina (58%), 309 Caridina (36%), 45 Amano, and 6 Sulawesi. The single most-listed morph was the Amano shrimp — the hobby's utility animal — followed by Fancy Tiger and Bloody Mary. The full census, with per-morph counts, is in What US shrimp vendors actually sell.
Typical per-shrimp money, July 29 medians: Neocaridina $4.20, Caridina $6.65 (the Caridina premium, measured), Amano $6.75. Pack size moved per-animal prices far more than anything else in July — the single-vs-pack curve is measured in The bulk discount.
Tracking notes for the record
- The Shrimp Farm has a 7/21–7/27 gap in our history: our collector broke when the vendor moved its product grid to client-side rendering, and was rebuilt on 7/27 against the site's structured data. The gap is ours, not the market's; gap days are simply not compared.
- Collection began July 15, so this report covers a half month. From August the reports cover full months.
What to watch in August
- Whether the zero-repricing streak survives a full month, and which vendor breaks it first.
- Whether the one heavy sale-tag catalog rotates its tags (which would show up as repricings) or holds them as standing state.
- The first full month of morph-level history — enough accumulated data to say whether cross-vendor medians hold as inventory turns over.
