Abstract
Cory cat, Corydorus (sic) aeneus (Gill, 1858) are popular among the hobbyists all over the world. They were reared successfully in glass aquaria and small cemented tanks in Kolkata, India. The females attained sexual maturity at the age of 12.2 ± 1.8 SD months while the males took 24.0 ± 1.6 SD months to take part in reproduction. Females are larger and more rounded than the males while males are attractive because of the dorsal fin. At a temperature range 14–22o C breeding was continued during November to March period in Kolkata, West Bengal, India. Cooling of egg laying substratum stimulated spawning to a great extent. Under favourable thermal condition breeding took place at an interval of 10.4 ± 2.1 SD days. Brood size varied from 175–225 and on average 80 % eggs were fertile. Water quality management and supply of proper food proved successful to establish an economically viable farm through the spread of indoor aqua business.
