Our work intends to investigate a comparative study on the morphometric data and nutritional evaluation in Xiphophorus helleri provided with commercial and domestic feed. The result revealed better mean length gain(1.30±0.360cm), mean weight gain(0.95±0.051g), SGR(1.59±0.068), FCR(0.113±0.003) and survival rate (90%) in domestic feed (DF) compared to a commercial diet. It was devoid of proximate composition when bought for the study(CF) yielded decelerated values of mean length gain(1.23±0.115cm), mean weight gain(0.91±0.072g), SGR(1.51±0.0005), FCR(0.133±0.004) with survival rate of 80% thereby necessitated the selection of accurate feed to flourish the bio stress reliever i.e., the ornamental fishes.
