Taiwan Torrent Carp
Acrossocheilus paradoxus
A barred Acrossocheilus of Taiwan's mountain streams — and the same species behind a locality record from Leishan, Guizhou, in FishBase, where it is listed under the name 台湾光唇鱼. Despite the Chinese name 台湾石鲽, it is NOT a flatfish or flounder at all: it is a cyprinid, a member of the carp family, built for life over rocks in fast, clear water.
Seasons · Peak

Identifying features
- A carp-family fish — deep-ish, laterally compressed body with a forked tail, NOT a flatfish: both eyes are on opposite sides of a normal, upright head
- Bold dark vertical bars on a golden-olive body, strongest in juveniles and stream fish
- Two pairs of short barbels at the mouth corners, the clearest proof it is a cyprinid barbel, not a flounder
- Thick lips and a slightly underslung mouth for grazing stones in current
- Dorsal fin tall and dark-edged; breeding males colour up and develop tubercles
Habits
- Lives in clear, fast mountain streams in Taiwan, holding over rock and gravel
- Grazes algae and picks small invertebrates from stones between riffles and pools
- Males guard eggs in the breeding season, like other Acrossocheilus
- The Leishan, Guizhou record shows the species (or its listing) reaches mainland mountain streams under the name 台湾光唇鱼

Where to find them
- Rock pools below rapids in Taiwan hill streams
- Slow pockets behind boulders in clear creeks
- Pool tails where current delivers insects
Where they live
How to catch them
Stream small-hook bottom fishing River
Rig: Short light rod, tiny split shot and size 12-16 hook resting among rocks
Bait/lure: Small worm pieces and tiny shrimp
Key tip: Keep the bait down in the pockets behind boulders; torrent fish dart out, take and return fast.
Light float drift, Acrossocheilus style River
Rig: Fine float rig drifted through runs and pool tails, as for banded barbel
Bait/lure: Insect larvae and small dough baits
Key tip: Drift naturally with the current and strike at the first dip — these fish mouth baits quickly.
Best baits & lures
Baseline setup
- Rod: Short light spinning rod
- Line: 4-6 lb mono
- Terminal: Tiny split shot or fine float, size 12-16 hooks
Recommended gear for this species
Rod · Best value
8' medium-heavy catfish rod
≈ US$80-130
Long enough to lob heavy bait rigs, strong enough to move a flathead off the bottom.
Reel · Budget
Baitcasting or 4000-6000 spinning reel
≈ US$60-100
Line capacity and drag for long runs — catfish and carp both make them.
Terminal · Budget
Circle hooks, sliding sinkers and cut-bait rigs
≈ US$15-25
A slip-sinker rig with a circle hook is the proven bottom setup for cats and carp alike.

Fair to good — a small stream fish eaten locally in Taiwan; many anglers release it to protect stream stocks.
