Most Viewed Aquarium Fish Online: FishyHub Marketplace Data
On FishyHub's US marketplace, the fish that shoppers save and like most are bettas: halfmoon plakats sit in the very high buyer-interest tier, halfmoons in the high tier and giant halfmoon plakats in the moderate tier. Across the whole marketplace, the fish people search for most include bettas, guppies, tetras, plecos, discus, angelfish, oscars and arowanas. FishyHub does not publish raw page views, so attention is measured here through saves, likes, searches and Feed videos.
Key Findings
- According to FishyHub data, halfmoon plakats are the US betta variety in the very high tier for wishlists, likes and "my tank" saves.
- FishyHub data shows halfmoon bettas draw high buyer interest in the US and giant halfmoon plakats moderate interest, so betta varieties dominate the US interest data.
- FishyHub search data shows arowana, betta, discus, guppy, oscar, pleco and tetra are among the terms shoppers search for most, across FishyHub's US and Singapore markets combined.
- FishyHub search data shows monster and predatory fish - channa, gar, bichir, arowana, oscar and flowerhorn - draw a very high level of searches.
- FishyHub Feed videos feature "other animals", the category for aquatic pets beyond fish, at a very high level, with scorpion fish also appearing.
- FishyHub data shows butterflyfish, clownfish, tangs and wrasses have very high supply in the US, giving online shoppers a deep range of marine fish to browse.
- FishyHub data does not yet include raw page-view counts or US buyer interest outside bettas, so it measures online attention through saves, likes, searches and Feed videos.
How FishyHub Measures Attention
"Most viewed" is a natural question for anyone writing about online fish shopping, but page views alone are a weak signal: a single listing can be opened many times by the same visitor, and a viral photo does not mean anyone wants the fish. FishyHub instead looks at three kinds of deliberate action:
- Buyer interest - wishlists, likes and "my tank" saves, where a shopper marks a specific fish as one they want or keep.
- Searches - what shoppers type into FishyHub's search box.
- Feed - what FishyHub's short video feed shows, a sign of what sellers and keepers choose to film.
In the US, buyer interest is currently recorded for betta varieties only, because the US marketplace is new. Search data combines the US and Singapore markets.
Bettas: The Fish Americans Save Most
| Betta variety | US buyer interest | US supply | US price tier |
|---|---|---|---|
| Giant halfmoon plakat | Moderate | Limited | Upper mid-range |
| Halfmoon | High | High | Upper mid-range |
| Halfmoon plakat | Very high | High | Mid-range |
Bettas are made for online browsing. Most betta listings show the exact fish being sold, photographed against a dark background with fins spread, so shoppers compare individual animals rather than a stock photo. Color patterns such as koi, nemo, galaxy and solid metallics make each fish distinct, and that encourages saving favorites to come back to.
Why the halfmoon plakat leads interest
Halfmoon plakats offer show-style finnage in a compact, active fish with short fins that are less prone to damage. In the US they sit in the mid-range price tier with a narrow price spread, so a buyer can choose an eye-catching fish without paying collector prices. Interest is running ahead of supply for this variety.
Giants: admired but scarce
Giant halfmoon plakats grow considerably larger than standard bettas and take longer to raise. US listings are limited, and even moderate interest clearly outpaces what is on offer. For shoppers, a saved giant is often a fish to watch for rather than one to buy immediately.
What Shoppers Search For
FishyHub's search data, which covers the US and Singapore together, puts these terms in the very high search tier (alphabetically): angelfish, arowana, barb, betta, bichir, catfish, channa, crab, discus, eel, flowerhorn, gar, gourami, guppy, koi, molly, oscar, pleco, puffer, shrimp, snail, tank, tetra and turtle.
Two patterns stand out.
Community classics
Betta, guppy, molly, tetra, angelfish and pleco are the backbone of freshwater keeping. People search for them by name because they already know what they want, often to compare varieties and prices.
Big, bold and predatory fish
A striking share of the very high search tier is made up of large or predatory fish: arowana, bichir, channa, eel, flowerhorn, gar, oscar and puffer. These are fish with personality - they recognize their keepers, hunt, and grow into the focal point of a big tank. Searches for them are often aspirational: shoppers look, compare and plan long before they buy. In the high search tier, terms such as "monster fish", "stingray" and "snakehead" reinforce the pattern.
US buyers should note that snakeheads (channa) are listed as injurious wildlife under US federal law, so they cannot be imported or moved across state lines, whatever their online popularity.
What FishyHub Feed Shows
FishyHub Feed is the marketplace's short-video stream. Its very high tier is the "other animals" category - aquatic pets beyond fish, a group whose search terms include axolotls, frogs and hermit crabs. Scorpion fish, the family that includes lionfish, also appear regularly. Video favors animals that move, feed or behave in interesting ways, which is why these groups get more screen time than their share of listings would suggest.
Where the US Range Is Deepest
Interest follows what is available to browse. On FishyHub's US marketplace these fish have very high supply, so online shoppers see a broad range of them (alphabetically):
- Butterflyfish
- Clownfish
- Discus
- Gobies (marine)
- Guppies
- Plecos
- Tangs and surgeonfish
- Tetras
- Wrasses
Marine fish such as butterflyfish, tangs and wrasses are among the most visually striking fish in the hobby, and a deep listing range invites browsing even from shoppers who keep only freshwater tanks.
Methodology
This page is based on FishyHub marketplace activity over the period from October 2024 to October 2026. For the US, we looked at wishlists, likes and "my tank" saves, active listings and their price tiers, and new listings over time. Search terms and FishyHub Feed categories cover FishyHub's US and Singapore markets together. All findings are reported as tiers, not figures.
FishyHub does not report raw page views. US buyer-interest data currently covers betta varieties only, and the US market has no order history in this data. FishyHub does not report interest by state, and the data covers fish listed by independent merchants on FishyHub, not the wider online aquarium trade.
