Goldfish Food Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Goldfish is the best-performing goldfish food brand in July 2026, moving 70,000 units across 2 ASINs for 59.3% of Top 10 volume. Tetra follows with 36,000 units (30.5%), ahead of Kaytee on 8,000 units (6.8%).

With 4 brands splitting the Top 10 and 96.6% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $10.81 to $24.90, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0017JAPMQ booked 4K units at $8.91, with ▲ 300.0% MoM change. On the growth side, B00026Z48A leads positive momentum with ▲ 275.0% MoM growth on 3K units, with B0002APNCS close behind at ▲ 150.0% MoM on 1K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
