Most Searched Aquarium Fish in 2026
The most searched aquarium fish in 2026, in FishyHub's search data, are bettas, guppies, tetras, plecos, angelfish, discus, arowana and oscars, along with barbs, bichirs, catfish, channa, eels, flowerhorns, gars, gouramis, koi, mollies and puffers in the same top search tier. For American shoppers, most of these are well stocked on FishyHub's US marketplace, but arowana and oscars are searched far more than they are listed, and some searched fish, such as snakeheads, are restricted in the US.
Key Findings
- FishyHub search data shows angelfish, arowana, barbs, bettas, bichirs, catfish, channa, discus, eels, flowerhorns, gars, gouramis, guppies, koi, mollies, oscars, plecos, puffers and tetras in the most searched tier of fish names.
- FishyHub data shows barbs, catfish, discus, guppies, plecos and tetras are both heavily searched and among the most widely listed freshwater fish in the US.
- On FishyHub, arowana and oscars are heavily searched but have limited US listings, so American shoppers looking for them face a scarce supply.
- FishyHub search data shows shoppers looking for specific varieties, such as pea puffers, Endler's livebearers, wild bettas, giant bettas and peacock bass, not just broad fish names.
- FishyHub search data shows equipment terms such as "tank", "fish tank", "filter", "gravel" and "driftwood" searched alongside livestock.
- FishyHub search data shows non-fish pets, including shrimp, snails, crabs, turtles and axolotls, among frequently searched terms.
- FishyHub Feed data shows the "Other Animals" category, which covers non-fish pets, is the most featured subject of Feed videos.
How This Search Data Works
FishyHub's search data records what shoppers type into the marketplace search box. It combines FishyHub's US and Singapore markets, so it shows what aquarium shoppers look for in general rather than in the US alone. To make it useful for American readers, this page reads each searched fish against FishyHub's US listings: is it easy to find, scarce, or not available at all? Terms are grouped by how often they are searched and listed alphabetically.
The Most Searched Fish Names
| Fish | Search level | US listings on FishyHub |
|---|---|---|
| Angelfish | Very high | High |
| Arowana | Very high | Limited (silver arowana moderate) |
| Barbs | Very high | Very high |
| Bettas | Very high | High |
| Bichirs | Very high | High |
| Catfish | Very high | Very high |
| Discus | Very high | Very high |
| Flowerhorns | Very high | High |
| Gars | Very high | Moderate |
| Gouramis | Very high | High |
| Guppies | Very high | Very high |
| Koi | Very high | Moderate |
| Mollies | Very high | Moderate |
| Oscars | Very high | Limited |
| Plecos | Very high | Very high |
| Puffers | Very high | Moderate |
| Tetras | Very high | Very high |
Channa and eels are also in the top search tier. Freshwater eels are not tracked as a separate US category, but marine eels have high US supply.
Also Heavily Searched
The next search tier includes apistogramma, bass, cichlids, corydoras, danios, gobies, goldfish, loaches, platies, ranchu, rasboras, ricefish, sharks, snakeheads, stingrays and wild bettas. Specific varieties appear here too: butterfly koi, pea puffers, Endler's livebearers, and named snakeheads such as toman.
Easy to Find: Searched and Well Stocked
For American shoppers, the good news is that most of the most searched fish are plentiful. Barbs, catfish, discus, guppies, plecos and tetras are in the top search tier and in the most-listed US supply tier on FishyHub. Many of them are also entry-level in price in the US, including barbs, catfish, guppies and tetras. Angelfish, bettas, bichirs, flowerhorns and gouramis have high US supply, so choice is good there too.
Hard to Find: Searched More Than Listed
Some fish are searched far more often than they are listed in the US:
- Arowana. Arowana sit in the top search tier, but black and jardini arowana have limited US listings and sit in the collector / premium price tier. The Asian arowana most hobbyists picture is protected under US wildlife law, which limits what can be sold in the country, so most US arowana are silver, black or jardini.
- Oscars. Oscars are a classic American "pet fish", heavily searched, yet US oscar listings are limited and entry-level in price. Large fish are costly to ship, which may hold back online supply.
- Koi and mollies. Both are heavily searched with moderate US supply. Koi buyers often prefer to choose fish in person, and mollies are widely sold in local stores.
Searched but Restricted in the US
Some searched fish are global favorites that American shoppers cannot freely buy:
- Snakeheads (channa). Heavily searched, especially by hobbyists in Asia, but snakeheads are restricted under US federal law and they do not appear in FishyHub's US listing data.
- Stingrays. Freshwater stingrays are heavily searched; several states restrict them, and stingrays do not appear in FishyHub's US listing data.
- Axolotls. Popular and widely searched, but some states, including California, restrict keeping them.
Always check your state's rules before buying an unusual animal.
What the Searches Say About Shoppers
People search by type, then narrow down
Broad words such as "betta", "guppy" and "shrimp" are searched more than specific varieties. Shoppers start wide and then filter, which is why category pages and clear listing titles matter.
Collectors search by name
Specific terms such as "rosetail", "feathertail", "red tail catfish", "galaxy rasbora" and "altum" show collectors looking for exact fish. These terms are searched less often, but each search is a strong buying signal.
Fishkeeping is more than fish
"Tank", "filter", "gravel", "sand", "plants", "moss" and "carbon dioxide" searches show shoppers setting up whole aquariums. Non-fish pets such as isopods, frogs, hermit crabs and jellyfish are searched too, and FishyHub Feed videos feature the "Other Animals" category more than any other subject.
Methodology
This page uses FishyHub search terms over the period from October 2024 to October 2026, grouped into search tiers (very high, high, moderate, limited), together with FishyHub's US listings, listed prices and Feed video categories. Findings are tiers, not figures, and terms within a tier are listed alphabetically.
Search terms combine FishyHub's Singapore and US markets and cannot be split by country, so search levels are not US-only. FishyHub does not report state-level data. Notes on US wildlife and state rules are general information, not legal advice, and are not FishyHub findings.
