Koi fish (A. testudineus) is traditionally a popular type of fish in this region. This fish is highly popular for its high nourishing quality and prolonged freshness. It is found in most of the fresh water bodies and is abundantly available from June to September. The investigation reported here had been carried out with the main objective to find the fish growth (A. testudineus) fed on formulated fish feeds reared in eight different tanks for a period of 60 days. Objective of the experiment also included to find the feed utilization by the experimental fish (A. testudineus). Optimum level of protein for the fish growths was also determined. Sabinco and three formulated fish feeds were used in the feeding and rearing trial of the fish (A. testudineus).Clean the tanks properly and take pure water at measured amount. Give a proper amount of oxygen to the fish tanks. The three tanks are clean at every three days ones and the water also change the every three days ones. Sometimes the fish tanks are kept under the sunlight to avoid some of the microorganism’s growth. T1, T2, T3 are the feeding samples. They are T1 is apple, T2 is potato, T3 is earthworm. These samples are taken and feeding to the fish during to the 5 weeks ratio. Then the measured food samples are feeding the koi fish every day. The koi fish is measured at every week once. Initial growth rate T1-1.5, T2-1.5, T3-2.0.Week five growth rate 5.7, .1, 7.3.T3-7.3 is an earthworm it only give the maximum amount of fish growth. Then second and third T2 and T1 is a potato and apple gives the growth to the fish
