Climbing perch
Anabas testudineus
Also calledKoi কই (Bengali) · Kavai (Hindi) · Pla mo ปลาหมอ (Thai) · Puyu (Malay) · Cá rô đồng (Vietnamese) · Panayeri (Tamil)
A small, armoured air-breather that can 'walk' across land on its gill covers and fins in search of new water. It is a beloved Bengali food fish, sold alive in markets because it survives hours out of water.
The climbing perch is a species of amphibious freshwater fish in the family Anabantidae. A labyrinth fish native to Far Eastern Asia, the fish inhabits freshwater systems from India, Bangladesh and Sri Lanka in the west, to Southern China in the east, and to Southeast Asia west of the Wallace Line in the south.

What it can do
- iBreathes air through a labyrinth organ above the gills
- iiMoves over land by rocking on spiny gill covers and pushing with its fins and tail
- iiiSurvives out of water for hours if kept damp, and buries itself in mud in the dry season
- ivTolerates stagnant, warm, oxygen-poor and slightly brackish water
In the field
Field marks
- aSmall, robust, perch-like body with rough scales
- bOlive to grey-green with a dark spot at the base of the tail and often one behind the gill cover
- cSerrated gill cover with sharp spines
- dLong spiny dorsal fin
- Not to be confused with
- Gouramis (Trichogaster) are thinner and have long, thread-like pelvic fins. Snakeheads have a long, cylindrical body and a flat head.
- Where to see it
- Village ponds and paddies of Bangladesh and West Bengal; live tanks in markets in Dhaka, Kolkata, Bangkok and Kuala Lumpur
- When
- Resident; breeds at the start of the rainy season (May–August); overland movements after heavy rain
Life & habits
- Diet
- Omnivore: insects, small fish, shrimp, worms and plant matter
- Habitat
- Shallow, vegetated still waters: swamps, paddies, ponds and canals
- Size
- Usually 10–20 cm; up to about 25 cm
- Lifespan
- Around 5–8 years
After heavy rain it may leave drying pools and travel overland at night to new water. Spawning pairs release floating eggs in the rainy season.

Marginalia
In 1797 a Danish East India Company officer, Daldorf, reported seeing one climbing a palm tree near Tranquebar, which gave the fish its English name and its genus name Anabas, Greek for 'climber'. Most biologists doubt the tree story but accept that it travels over land.
Curiosity
Its species name testudineus means 'tortoise-like', after its tough, armoured head and scales.
