Top 10 Rare Aquarium Fish Singapore Roundup: Specialist Imports

Specialist importers in Singapore quietly bring in fish that never appear in mass-market shops. The top 10 rare aquarium fish Singapore hobbyists actually have access to — through Iwarna, Polyart, C328 special orders and a handful of Carousell brokers — span monster predators, designer cichlids and oddball nano picks. This roundup from Gensou Aquascaping at 5 Everton Park flags pricing tiers, legal status under AVS regulations, and the species that need CITES paperwork before purchase. Rarity here means scarce in local retail, not necessarily rare in nature.

1. Goliath Tigerfish (Hydrocynus goliath)

Congo predator brought in by Polyart and Iwarna on prior order, SGD 8,000-15,000 for a 60cm juvenile. Adult 120cm, 1,500-litre minimum. Feeds on whole fish; switching to dead food takes weeks of conditioning.

2. Zebra Pleco L046 (Hypancistrus zebra)

Captive-bred only since the 2004 export ban from Brazil. Singapore tank-bred juveniles run SGD 250-600. Adult length 10cm, 100-litre tank, stable 28-30°C with strong flow. Look for clean black-and-white banding without smudges; grading directly affects breeder value.

3. Polypterus Endlicheri Endlicheri (Polypterus endlicheri)

African bichir reaching 60cm, dragon-like crawlers that breathe air. Wild-caught SGD 200-800 depending on size; rarer morphs like Platinum and Albino push past SGD 1,500. 600-litre tank, lid-loaded because they crawl out. Iwarna stocks them irregularly.

4. Datnoid (Datnioides microlepis)

Indonesian Tiger Fish, vertically banded gold and black. Legal in Singapore unlike some neighbouring countries. SGD 300-3,000 depending on banding grade and origin (Indo, Thai or Borneo). 60cm adults, 600-litre tank, predatory but slow.

5. Freshwater Stingray (Potamotrygon sp.)

Regulated under AVS — keepers need notification for ownership of certain species. Pearl, Black Diamond and Polkadot grade SGD 1,500-15,000+. Disc 40-50cm at adulthood, requires 600-litre minimum, sand substrate, no rocks above 5cm height. Iwarna and Polyart handle most of the local trade.

6. Wrestling Halfbeak (Dermogenys pusilla)

Surface-dwelling livebearer once kept for fighting in old Malay culture. SGD 4-8 each at specialist shops. Adult length 6cm, 60-litre tank, group of six minimum with mostly females. Eats only floating food and live insect-sized prey.

7. African Butterflyfish (Pantodon buchholzi)

Surface ambush predator with pectoral fins shaped like wings. SGD 35-60 each, available through Iwarna and Polyart. Adult 12cm, 200-litre tank, tight lid mandatory because they jump at lights. Feeds on insects and small fish at the surface.

8. Peacock Gudgeon (Tateurndina ocellicauda)

Papuan nano gem with rainbow body and ocelated tail. SGD 25-45 each at specialty stores. 7cm adults, 60-litre tank, peaceful pair or trio. Cave-spawning behaviour observable in home tanks. Pair with a dark substrate to deepen body colour.

9. Pea Puffer (Carinotetraodon travancoricus)

Smallest puffer in the trade at 2.5cm adult length. SGD 8-15 each, occasionally available at C328 and Iwarna. Group of one male to three females in a 40-litre tank. Snail diet mandatory — pair with a frozen bloodworm food rotation and a Malaysian trumpet snail breeder tank for live prey.

10. Elephant Nose Fish (Gnathonemus petersii)

Weakly electric African mormyrid with a sensitive proboscis used to sift sand. SGD 35-65 each at Iwarna. 30cm adults, 200-litre tank, single specimen unless 600-litre+ where a group of five is possible. Live or frozen food only — they ignore pellets initially.
