Fastest-Growing Aquarium Fish in Singapore
The fastest-growing aquarium fish in Singapore, on FishyHub, are angelfish, discus, guppies, platies and halfmoon plakat bettas, where rising activity comes with prices trending up. Bettas as a whole, reef fish and marine invertebrates are rising too. At the same time, several long-established favourites such as tetras, danios and loaches are cooling, even though they still sell strongly.

How Growth Is Measured
FishyHub measures momentum as new listings and orders in the recent year against the year before, and reports each category as rising, steady or cooling. Singapore is FishyHub's established market, so a rising label here reflects real change in what local hobbyists buy and sell. To find the strongest growth, this page pairs momentum with price direction: a category that is rising while its prices also trend up is growing on both the selling and buying side.
The Strongest Growth: Rising Activity, Rising Prices
| Fish | Activity | Price direction | Typical price tier |
|---|---|---|---|
| Angelfish | Rising | Trending up | Mid-range |
| Discus | Rising | Trending up | Upper mid-range |
| Guppies | Rising | Trending up | Upper mid-range |
| Halfmoon plakat bettas | Rising | Trending up | Upper mid-range |
| Platies | Rising | Trending up | Entry-level |
Why these fish are growing
- Angelfish and discus have strong local breeding, and new colour strains keep collectors coming back. Both have high purchases and high buyer interest on FishyHub, so growth is backed by real demand.
- Guppies benefit from Singapore's active show-guppy scene. New named strains keep buyers trading up, which helps explain prices trending up for named guppies.
- Halfmoon plakat bettas combine very high supply with high interest, and buyers are paying more for well-bred fish.
- Platies are a classic beginner fish, and rising activity with firmer prices suggests new hobbyists entering the market.
Bettas: Growth Across the Board
Bettas as a category are rising in Singapore, and so are most named varieties: alien, crowntail, delta tail, double tail halfmoon, double tail halfmoon plakat, dumbo, giant halfmoon plakat, halfmoon, halfmoon plakat, imbellis, mahachai, startail and veiltail. Splendens and macrostoma are steady, and smaragdina is cooling.
The rise across so many varieties points to a betta scene that is broadening, with keepers trying wild-type and hybrid lines as well as show forms. Supply runs ahead of demand for most bettas, so the growth is mainly coming from sellers listing more fish.
The Reef Side Is Rising
Marine livestock is the smaller share of FishyHub's Singapore listings, but it is growing:
- Anemones - rising
- Clownfish - rising
- Damselfish - rising
- Marine fish overall - rising, with prices stable
- Marine invertebrates - rising, prices trending up, demand ahead of supply
- Triggerfish - rising
Reef keeping in Singapore usually means running a chiller or keeping the room cool, which has held the marine side back. Growth here suggests more keepers are taking that on, often with compact reef tanks that suit a flat.
Rising Collector Fish, Easing Prices
Flowerhorns and silver arowana are rising in Singapore while their prices ease. That is typical of a category where more sellers are listing fish: buyers get more choice, and prices soften. Gars and stingrays are rising too. The monster fish category as a whole, however, is cooling, with bass, knifefish and bichirs all cooling.
Cooling Does Not Mean Unpopular
Some of Singapore's best-selling fish are cooling:
| Fish | Activity | Purchases |
|---|---|---|
| Algae eaters | Cooling | Very high |
| Danios | Cooling | High |
| Loaches | Cooling | Very high |
| Neocaridina shrimp | Cooling | Very high |
| Tetras | Cooling | Very high |
These are mature categories. They already sell in large volumes, and demand still runs ahead of supply for each of them, so a cooling label means activity is levelling off rather than falling away. For buyers, they remain easy, affordable choices.
Other Fish on the Rise
Smaller rising groups worth watching in Singapore include apistogramma, badis, bubble eye goldfish, Caridina shrimp, hatchetfish, rainbowfish and tilapia. Among aquatic plants, epiphytes, foreground plants and tissue culture plants are rising, which fits the steady growth of planted tanks in local homes.
Methodology
This page uses FishyHub marketplace activity in Singapore over the period from October 2024 to October 2026: momentum (new listings and orders in the recent year against the year before), listed prices and how they are moving, orders, buyer interest (wishlists, likes and "my tank" saves) and demand relative to supply. Findings are directions and tiers, not figures, and fish are listed alphabetically.
The data covers livestock sold by independent merchants on FishyHub, and does not measure growth in the number of people keeping fish in Singapore or sales by shops and farms directly. Hobby context, such as the use of chillers for reef tanks, is general knowledge.
