Five experimental diets containing 0, 5, 10, 15, and 20% of mallow leaves meal M<sub>0</sub>, M<sub>5</sub>, M<sub>10</sub>, M<sub>15</sub>, and M<sub>20</sub> respectively, were prepared by replacing barley and yellow corn. A total of 90 fish (2.55<a name="_Hlk107753220">±</a>0.17 g) were used, distributed equally into fifteen plastic tanks at a rate of 6 fish per tank. The experiment lasted for 60 days, during which fish were fed the experimental diets to satiation twice daily. Results exhibited a gradual significant (<a name="_Hlk107752480"><i>p</i></a><0.05) increase in the feed intake FI (r=0.935) of the fishes with increasing dietary mallow leave replacement. There were no significant differences (<i>p</i>>0.05) in specific growth rate (SGR), feed conversion ratio (FCR), and protein efficiency ratio of sailfin molly fed control (M<sub>0</sub>) diet compared to fish fed on M<sub>5</sub> and M<sub>10 </sub>diets at the end of the experiment. Increasing the involvement of mallow in M<sub>15</sub> and M<sub>20</sub> diets led to inhibited SGR, FCR, and PER significantly (<i>p</i><0.05) compared to the control diet. In conclusion, using mallow dried meal in the diets at a 10% level was proved to be more suitable with no noticeable adverse effects on the growth and feeding efficiency of experimental fish.</span></span></span></span></span></span></span>
