Abstract: Ability to change colour is used by fish for many kinds of signals in many different social and environmental settings. Change in colouration patterns themselves have been subject to both natural and sexual selection. Guppies (Poecilia reticulata) have been an important fish system for examining the anti-predatory behaviour. Guppies are popular ornamental fishes all over the world due to its bright colours and cheap maintenance cost in aquarium. Under predation effect colouration of guppies were affected. To study huddles coming due to predation effect for the development of colours and growth in guppies following experiment was carried out under which three sets of conditions were maintained. Absence of predation, mild predation and high predation effects were maintained during experiment to check the mating behaviour, growth and colour development in new born guppies. The results indicated that the predation was found to have a profound effect on mating behaviour, colour development and growth.
