The Rise of Rare Aquarium Fish in Singapore: What Hobbyists Are Searching For
Singapore hobbyists looking for rare fish on FishyHub search above all for wild bettas, named snakehead species and unusual colour forms. On the marketplace, the rare end in Singapore is led by wild bettas such as Api Api, Imbellis, Mahachai, Smaragdina and Macrostoma, collector-tier arowana, and a set of oddballs including archer fish, elephantnose and monofish, all with limited supply. Rarity does not always mean demand, though: super red arowana sit in the collector tier with supply ahead of demand.

Rare in Singapore Means Something Different
Singapore sits at the centre of the region's ornamental fish trade, close to the forest streams and peat swamps of Malaysia, Indonesia and Thailand where many prized species live. Fish that are exotic rarities elsewhere can be fairly easy to find here. What counts as rare in Singapore tends to be wild species collected in small numbers, protected fish, and the best grades of popular lines.
What Rare-Fish Hunters Search For
FishyHub's search terms combine its Singapore and US markets. Grouping the rare and unusual terms by theme:
| Theme | Terms searched (search tier) |
|---|---|
| Bettas | wild betta (high), giant betta (moderate), rosetail (moderate), blue alien male (limited), pink betta (limited) |
| Snakeheads | channa andrao and channa auranti (high), channa barca (moderate), channa cobra (limited) |
| Colour forms | albino (high), platinum (limited) |
| Flowerhorn lines | fei feng (moderate), luohan (limited) |
| Oddballs | axolotl and vampire crab (high), mudskipper and arapaima (limited) |
Searchers name the exact fish or line they are after. That is typical of experienced keepers who have done their research and are watching for a particular fish to be listed.
Wild Bettas: Singapore's Rare-Fish Speciality
| Wild betta | Supply | Price tier | Buyer interest | Momentum |
|---|---|---|---|---|
| Api Api | Limited | Collector / premium | Limited | Not tracked |
| Imbellis | Limited | Upper mid-range | Limited | Rising |
| Macrostoma | Moderate | Collector / premium | Not tracked | Steady |
| Mahachai | Limited | Upper mid-range | Moderate | Rising |
| Smaragdina | Limited | Upper mid-range | Moderate | Cooling |
| Splendens (wild-type) | Limited | Upper mid-range | Limited | Steady |
Wild bettas come from habitats under pressure from land clearing, and several are collected only in small numbers. Macrostoma, from Borneo, is admired for its colour and is protected in parts of its range, which keeps it in the collector tier. Mahachai, from brackish swamps in Thailand, and Imbellis are rising. Keepers in Singapore have an advantage here: the island's soft water, warm rooms and easy access to Indian almond leaves make it straightforward to recreate the tea-coloured water these fish need.
Arowana: Rare by Design
Asian arowana are bred on licensed farms and sold with certificates and microchips, so supply is controlled. Black, crossback and super red arowana all sit in the collector tier with limited supply. The super red result is a useful reminder: limited supply alone does not create demand. With buyer interest limited and supply ahead of demand, buyers of top-grade arowana have time to choose.
Oddballs With Limited Supply
Archer fish, butterfly fish, elephantnose and monofish all have limited supply in Singapore. Each has its own challenge: archer fish and monos grow best in brackish water, elephantnose need soft water, sandy floors and live food, and freshwater butterfly fish need a calm, covered surface. Hatchetfish are the standout among small rarities, with demand clearly outpacing supply and activity rising.
Among goldfish, bubble eyes are scarce, with demand ahead of supply and a very wide price spread, because their delicate eye sacs make good specimens hard to raise and ship.
Marine Rarities
Marine livestock is the smaller share of FishyHub's Singapore listings. Tangs, triggerfish and wrasses all have limited supply, and triggerfish are rising. In Singapore's climate a marine tank usually needs a chiller, which keeps the marine side a specialist interest.
Methodology
This page is based on FishyHub marketplace activity in Singapore over the period from October 2024 to October 2026. We looked at active listings, listed prices, orders, wishlists, likes and "my tank" saves, momentum compared with the year before, and the search terms shoppers use on FishyHub. Findings are reported as tiers and directions, not figures.
Search terms combine FishyHub's Singapore and US markets. "Not tracked" means the signal was not strong enough to report. The data covers fish sold through independent merchants on FishyHub and does not measure the wider trade, fish farms' direct sales or how many keepers own rare fish.
