The grass carb fingerlings (initial weight: 10+1.24 gm) were caught from earthen ponds and maintained in 12 glass aquaria (35 cm x 70 cm x 40 cm) in 4 treatments (3 replicates per treatment) control, Garlic (Ga) TGa, Probiotics (TPr) and Moringa (TMo) with stocking densities (10 fish/aquarium). The fish were fed 5 % of body weight (50% commercial pellet diet, 50% Azolla plant) and Garlic (Ga), Probiotics (Pr), Moringa (Mo) were used as food additives (1%/Kg diet) in the experimental groups. The diet TGa, Tpr and TMo gave the highest weight gain of (11.92+0.17, 12.09+0.22 and 12.00+0.11g) whereas, the lowest (10.36g) was in control diet after 90 days. The highest Specific growth rate (SGR) (1.31+0.01, 1.32+0.02 and 1.31+0.01) was recorded in treatment TGa, Tpr and TMo, respectively which was significantly different from control (1.18).  The fish groups fed diet TGa, Tpr and TMo showed significantly (P
