Where Rare Aquarium Fish Are Most Available in Singapore
Rare aquarium fish in Singapore are most available where specialist sellers are concentrated, and on FishyHub that is Central Singapore, which has the most livestock sellers, followed in the next tier by the North-East and West. FishyHub has no species-by-region breakdown; what its Singapore listings do reveal is which fish are scarce: Asian arowanas, wild bettas such as Api Api, Imbellis, Mahachai, Smaragdina and wild-type Splendens, bubble eye and wakin goldfish, oddballs such as archer fish, elephantnose, monos and ropefish, and marine tangs, triggerfish and wrasse. Some of these rarities sell out quickly; others wait for the right buyer.
Key Findings
- Specialist stock is easiest to reach locally in Central Singapore, which FishyHub data shows has the most livestock sellers, and in the North-East and West, which have many.
- FishyHub data shows limited Singapore supply of black, crossback and super red arowanas.
- FishyHub data shows limited Singapore supply of the wild bettas Api Api, Imbellis, Mahachai, Smaragdina and Splendens.
- FishyHub data shows limited Singapore supply of archer fish, badis, butterfly fish, elephantnose, monos, ropefish, bubble eye goldfish and wakin goldfish.
- FishyHub data shows hatchetfish, minnows and freshwater clams are scarce in Singapore yet demand clearly outpaces supply, so they sell quickly.
- FishyHub data shows super red arowanas, Api Api and Splendens bettas, monos and butterfly fish are scarce but supply still runs ahead of demand, giving collectors time to choose.
- FishyHub data shows marine tangs, triggerfish, wrasse, marine shrimp and sea stars are in limited supply in Singapore, where freshwater holds the larger share of listings.
What Counts as Rare on FishyHub
A category counts as rare here when it sits in FishyHub's limited-supply tier in Singapore: few active listings at any time. Rarity and price overlap but are not the same. Super red and crossback arowanas and Api Api bettas are scarce and collector-priced, while hatchetfish, minnows and badis are scarce yet sit in the entry-level tier.

Rare and Wanted, or Rare and Waiting
FishyHub compares purchases and interest against listings, which shows how quickly scarce fish move.
| Rare group | Demand vs supply | What it means |
|---|---|---|
| Hatchetfish, minnows, freshwater clams | Demand clearly outpaces supply | Buy promptly when listed |
| Imbellis, Mahachai, Smaragdina bettas | Balanced | Steady interest, steady listings |
| Black and crossback arowanas, archer fish, elephantnose, ropefish | Balanced | Patient buyers can find them |
| Super red arowana, Api Api and Splendens bettas, monos, butterfly fish | Supply ahead of demand | Time to compare sellers |
Why These Fish Are Rare in Singapore
Asian arowana rules
Asian arowanas, including the crossback and super red, are protected species. In Singapore they are sold legally only as captive-bred fish from registered farms, each with a microchip and certificate. That paperwork, plus the years it takes to raise a quality fish, keeps listings few and prices in the collector tier. Interestingly, black arowana, a South American species, is also scarce locally.
Wild bettas depend on wild habitats
Api Api, Imbellis, Mahachai and Smaragdina are wild species from Southeast Asian swamps and peat forests. Some are bred by specialist hobbyists, but output is small, and several come from threatened habitats.
Space limits monster and oddball fish
Ropefish, monos and archer fish grow large or need brackish or specialist setups. Few HDB-based sellers have room to hold them, so listings are thin.
Marine is a smaller market
Freshwater dominates Singapore listings on FishyHub, and reef tanks are harder to cool in a tropical flat. With fewer reef keepers, fewer sellers stock tangs, triggerfish and wrasse.
Where to Look in Singapore
- Central Singapore: the most livestock sellers on FishyHub, so the best chance of a specialist nearby for viewing or self-collection.
- North-East and West: many sellers each, with good local options.
- North and East: fewer sellers locally, so buyers rely on island-wide delivery, which works well for rare fish too.
Regional seller data on FishyHub covers livestock in general, so a rare species can be listed by a seller in any region. Saving scarce categories to your wishlist is the surest way to catch new listings.
Momentum in Rare Categories
Activity in several rare categories is rising on FishyHub in Singapore, including Imbellis and Mahachai bettas, badis, bubble eye goldfish, hatchetfish and triggerfish. Crossback arowana, wild-type Splendens and minnows are steady, while Smaragdina and elephantnose are cooling. Rising categories may become a little easier to find as more sellers list them.
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 by category (to identify the limited-supply tier), listed prices, orders, wishlists, likes and "my tank" saves, demand relative to supply, listing momentum, and livestock seller regions. All findings are tiers and directions, not figures.
FishyHub does not report rare species by region; seller regions cover livestock in general. Notes on arowana rules, wild habitats and keeping requirements are general hobby knowledge. The data does not cover farms or shops selling outside FishyHub.
