Bronze Cory: The Corydoras That Started It All

In this guide

Overview

The bronze cory is one of the most widely kept catfish in the world, with an armoured, bronze-green body and the characteristic downturned, whiskered face shared by every Corydoras species. It comes from South America and reaches around six to seven centimetres, making it one of the larger commonly kept corys.

As one of the first Corydoras species to enter the aquarium trade, it remains a benchmark fish against which the hardiness of other corys is often measured, and is an excellent, forgiving choice for a first bottom-dwelling shoal.

Tank and water requirements

A group of six or more does well in a tank of sixty litres or more, with a soft sandy substrate that protects their delicate barbels from abrasion, an important detail often missed with sharp gravel. They are highly tolerant of a range of water conditions, including typical Indian tap water.

Good filtration matters, since corys are bottom feeders that spend much of their time sifting through substrate, but they are otherwise low-maintenance and forgiving of minor water quality lapses compared to many other bottom dwellers.

Diet and behaviour

Sinking pellets or wafers, supplemented with occasional live or frozen bloodworm, suit their bottom-feeding habits well. They will also clean up leftover food from other fish, though this should not be relied on as their sole food source.

Bronze corys are entirely peaceful and shoal actively at the bottom of the tank, making them an ideal, low-drama addition to almost any calm community setup.

Buying tips

• Among the cheapest and most widely available corys in India, often twenty five to sixty rupees per fish
• A genuinely good starter bottom-dweller given their hardiness and tolerance for imperfect water conditions
• Use a soft, rounded substrate rather than sharp gravel to protect their sensitive barbels
