Kolathur Fish Market is India’s most famous destination for ornamental fish and aquarium supplies. Tucked away in North Chennai, it has been a pilgrimage spot for hobbyists, breeders, and wholesale traders for decades.
In October 2025, everything changed.

Kolathur Fish Market History
Kolathur’s fish trade goes back more than 30 years.
The Street Era
Originally, over 500 local families ran small breeding units and shops along W-Mada Street. The lanes were narrow, prices were unbeatable, and Sundays felt like controlled chaos. If you wanted rare fish in South India, this was the place.
The Big Shift (2025)
In October 2025, the Tamil Nadu government inaugurated the Kolathur Ornamental Fish Trade Centre, a ₹53-crore project spread across 1.25 lakh sq. ft.
The goal was simple:
- Reduce traffic congestion
- Improve hygiene
- Support exports
- Give breeders international-standard facilities
The new complex now houses:
- 188 dedicated shops
- Fish health labs
- Cylindrical display tanks
- Training halls for breeders
Kolathur officially stepped onto the global aquarium map.
