Which Aquarium Fish Have the Highest Buyer Interest?
In the US, the aquarium fish with the highest measured buyer interest on FishyHub are show bettas, led by the halfmoon plakat, with the halfmoon in the high tier and the giant halfmoon plakat in the moderate tier. Interest data for the young US market covers bettas only so far, so for the wider picture we look at what shoppers search for: bettas, guppies, tetras, plecos, discus, angelfish, oscars, koi and puffers sit among the most searched fish on the marketplace.
Key Findings
- FishyHub data shows halfmoon plakat bettas have very high buyer interest among US-listed products, the strongest interest tier recorded in the US market.
- FishyHub data shows halfmoon bettas draw high US buyer interest, and giant halfmoon plakats draw moderate interest.
- FishyHub data shows US interest in halfmoon plakats runs ahead of supply, and for giant halfmoon plakats demand clearly outpaces supply.
- FishyHub search data shows angelfish, bettas, catfish, discus, guppies, koi, mollies, oscars, plecos, puffers, shrimp, snails and tetras among the most searched terms on the marketplace.
- FishyHub search data shows freshwater terms dominate the most searched tier, while marine terms such as clownfish, coral and anemone sit in the moderate search tier.
- FishyHub data shows US sellers list bettas in high supply with a wide price spread, so interest is spread across many price points.
- FishyHub data shows new US betta listings are rising across nearly every tracked variety.
What FishyHub Measures as Buyer Interest
On FishyHub, buyer interest means wishlists, likes and "my tank" saves: deliberate actions a shopper takes on a listing. In the US, this is interest from FishyHub users in US-listed products. Because the US market is new, interest is recorded so far for three betta categories only. That is narrow, but it is a clean, direct measure, and it gives a clear answer within bettas.
To widen the view, we add FishyHub search terms. Searches show what people come looking for. They combine the US and Singapore markets, so they describe shopper interest across FishyHub rather than in the US alone.
Measured US Interest: Show Bettas
| Betta | US buyer interest | Demand vs supply | US supply |
|---|---|---|---|
| Giant halfmoon plakat | Moderate | Demand clearly outpaces supply | Limited |
| Halfmoon | High | Balanced | High |
| Halfmoon plakat | Very high | Demand ahead of supply | High |
Listed alphabetically.
Why the halfmoon plakat leads
The halfmoon plakat combines a halfmoon's wide, D-shaped tail with the short fins of the fighting plakat. The result is a colorful, active fish that is less prone to fin damage than long-finned forms, ships more reliably, and suits a small desk or shelf tank. In the US it sits in the mid-range price tier, below the halfmoon, which makes it the most approachable show betta.
Halfmoons: the classic
Halfmoons remain the image most Americans have of a show betta. They draw high interest and sit in the upper mid-range price tier. With high supply, demand and listings are in balance, so buyers can find good fish without much waiting.
Giant halfmoon plakats: small supply, real demand
Giant plakats grow noticeably larger than standard bettas and take longer to raise. Their interest is moderate, but because listings are limited, demand clearly outpaces supply. For a buyer, that means good giants go quickly.

How Search Interest Compares With US Supply
Search interest and US listings line up well for most community fish. Tetras, guppies, barbs, catfish and plecos all have very high US supply, so shoppers searching for them find plenty. The gaps appear with big and unusual fish. Arowana and oscars are heavily searched but have limited US supply, and channa and stingrays, also searched often, are not listed in the US at all. Snakeheads are prohibited under federal law, and freshwater stingrays are restricted in several states.
Why Interest Patterns Look This Way in the US
- Bettas are the gateway fish. Many Americans start with a betta, often in a small heated tank. A heater matters across much of the country, especially in the Midwest & Central and East Coast & Northeast zones during winter.
- Online shopping favors fish you cannot find locally. Local fish stores stock common community fish. Show bettas with specific colors and forms are what many people go online to find.
- Marine interest is concentrated among reef keepers. US marine supply is strong, with clownfish, gobies, tangs, wrasses and corals all listed deeply, but marine terms sit in the moderate search tier. Reef keeping takes more equipment and experience, so its audience is smaller and more focused.
Methodology
This page draws on FishyHub marketplace activity over the period from October 2024 to October 2026: buyer interest (wishlists, likes and "my tank" saves) from FishyHub users on US-listed products, US active listings, price tiers, price spread and momentum, and search terms, which combine the US and Singapore markets. All findings are reported as tiers and directions, not figures.
US buyer interest is currently recorded only for halfmoon plakat, halfmoon and giant halfmoon plakat bettas, so FishyHub cannot rank interest across all US fish. The US market has no order history in this data. Legal notes reflect general hobby knowledge. The data covers FishyHub shoppers, not every aquarium keeper in the US.
