The Most Popular Aquarium Fish in Singapore: 2026 Rankings
In Singapore, the most popular aquarium fish on FishyHub in 2026 are small, affordable fish bought in groups: guppies, tetras and rasboras, along with bottom dwellers such as corydoras, loaches and algae eaters. Koi sit in the same most-purchased tier, and channa (snakeheads) and plecos draw some of the strongest buyer interest on the marketplace. FishyHub reports these rankings as tiers from orders, wishlists and listings, not as numbered positions.
Key Findings
- FishyHub marketplace data shows guppies, koi, tetras, rasboras, corydoras, loaches and algae eaters are among the most purchased aquarium fish in Singapore.
- FishyHub data shows channa draw very high buyer interest in Singapore even though they sit in the collector price tier, with purchases at a moderate level.
- On FishyHub, angelfish, discus, goldfish, halfmoon bettas, oscars, gouramis, barbs, puffers, rainbowfish, mollies, platies and danios form a busy also-popular tier in Singapore.
- FishyHub data shows demand clearly outpaces supply for small community fish in Singapore, including tetras, rasboras, danios and the guppy category as a whole.
- FishyHub data shows arowana are a small-volume collector market in Singapore, with limited purchases and buyer interest compared with community fish.
- Freshwater fish make up the larger share of FishyHub's Singapore listings, while marine fish, clownfish and damselfish are rising from a smaller base.
- FishyHub data shows Central Singapore has the most livestock buyers on the marketplace, with the North-East and West also busy.
How the Rankings Are Built
Singapore is FishyHub's established market, so its data includes orders as well as listings and buyer interest. A fish is placed in the most popular tier when its purchases or its wishlists and likes reach the top level on the marketplace. The next tier holds fish with high purchases or high interest. Fish are listed alphabetically within each tier, so the order on this page carries no meaning.
The Most Popular Tier
| Fish | Purchases | Buyer interest | Typical price tier |
|---|---|---|---|
| Algae eaters | Very high | Very high | Entry-level |
| Channa | Moderate | Very high | Collector / premium |
| Corydoras | Very high | Very high | Mid-range |
| Guppies | Very high | Very high | Upper mid-range |
| Koi | Very high | High | Upper mid-range |
| Loaches | Very high | Very high | Entry-level |
| Plecos | High | Very high | Upper mid-range |
| Rasboras | Very high | Very high | Entry-level |
| Tetras | Very high | Very high | Entry-level |
The pattern is clear: most of Singapore's best-selling fish are small, cheap and kept in groups. The exceptions are koi, a pond fish with a long following among Singapore's landed-home and condo owners, and channa, a group of predatory fish with a dedicated collector scene.
Why small fish dominate
- Space. Most Singaporeans live in HDB flats and condos, where a compact or nano tank fits on a shelf or console. Small schooling fish suit those tanks far better than large species.
- Planted aquascapes. Nature-style planted tanks are a big part of the local hobby, and rasboras, tetras and corydoras are the classic fish for them. Aquatic plants are among the most purchased items on FishyHub in Singapore too.
- Climate. Singapore's warm, steady temperatures mean most tropical fish need no heater, which keeps running costs low for beginners.
- Clean-up crews. Algae eaters, corydoras and loaches are bought alongside community fish to keep tanks tidy, which keeps their sales high.
Guppies: popular at every price
Guppies are an interesting case. The guppy category has very high purchases and very high interest, and demand clearly outpaces supply. Yet the typical guppy listing sits in the upper mid-range price tier with a wide spread, because Singapore has a strong scene for show-grade guppy strains, where matched pairs and trios of a named line cost far more than mixed fish.
Also Popular
These fish have high purchases or high buyer interest on FishyHub in Singapore:
- Bettas: halfmoon and mixed "Other Betta" lines (high purchases), with dumbo and halfmoon plakat bettas drawing high interest.
- Cichlids: angelfish and discus, both with high purchases and high interest.
- Goldfish: the goldfish category, orandas and ryukins.
- Larger fish: oscars, with high purchases and interest.
- Other tropicals: barbs, gouramis, killifish, puffers and rainbowfish.
- Livebearers and small fish: danios, minnows, mollies and platies.
The Big-Fish Culture
Singapore is known for its arowana, flowerhorn and channa keepers, and the data shows how this differs from the mass market. Arowana and flowerhorns sit in the collector tier with limited purchases: fewer people buy them, but each purchase is a considered one. The arowana's place in Chinese culture as a "dragon fish" linked with good fortune keeps it in demand, and Singapore's fish farms are known for breeding them. Channa stand out because they combine collector pricing with very high buyer interest, which points to many keepers watching and saving fish before they buy.
Where Singapore's Fish Buyers Are
FishyHub buyer data for livestock shows the most buyers in Central Singapore, many in the North-East and West, fewer in the East and the fewest in the North. Sellers follow a similar pattern, with the most in Central Singapore and the fewest in the East. Because the island is small and merchants deliver across it, a buyer in any region can choose from the full range of sellers.
Methodology
This page uses FishyHub marketplace activity in Singapore over the period from October 2024 to October 2026: orders, wishlists, likes and "my tank" saves, active listings, listed prices, demand relative to supply, and buyer and seller regions. All findings are reported as tiers and directions, not figures, and fish within a tier are listed alphabetically rather than in rank order.
The data covers livestock sold by independent merchants on FishyHub. It does not measure how many people in Singapore keep fish, total spending, or sales by fish farms and shops directly. Regional data covers livestock buyers and sellers in general, not individual species. Cultural and hobby context is general knowledge, not a FishyHub finding.
