The present study was conducted to determine the effects of high level red pepper supplementation to diet on the growth performance, coloration, histology, intestinal microflora and protection against Aeromonas sobria in Pseudotropheus acei. Two isonitrogenous (37% crude protein) and isocaloric (3831kcall/kg energy) experimental diets were prepared by adding of 15 % pepper meal to control diet. The feeding trial was conducted in triplicate for 90 day in aquariums (100-L). At the beginning of the experiment, twenty fish (initial weight 0.06 g) were stocked into each aquarium. The end of the experiment, fish fed red pepper supplemented to diets did not have any marked effect on the weight gain, feed conversion ratio, specific growth rate and survival. However, tail of female fish fed diet containing red pepper was showed increase significantly in pigmentation. High level red pepper addition to diet caused no pathological findings in any organs. Red pepper didn’t observed significant differences for protection to A. sobria infection. However, Aeromas and Pseudomonas counts in red pepper group were significantly lower than control groups.
