The aim of this study was to investigate the addition of different levels of aloe vera powder to diet and its effect on growth performance and blood indexes of goldfish. 120 fish with an average initial weight of    75.7 ± 0.03 g were fed for 56 days with diets containing 0, 5, 10 and 15 g/kg aloe vera powder. The result of growth indices showed that final weight increased in 5 and 10 g/kg treatments and was significant different with 15 g/kg treatment and control group respectively (P<0.05). Weight gain, weight gain percentage, specific growth rate and feed conversion ratio was different in 10 g/kg treatment with other experimental groups (P<0.05). RBC, hemoglobin and hematocrit percent increase in 5 g/kg treatment and were different with 15 g/kg treatment and control group (P<0.05). WBC and neutrophil percentage increased in 5 and 10 g/kg treatment and were different with 15 g/kg treatment and control group (P<0.05).  Also, the highest percentage lymphocytes was observed in 10 g/kg treatment, which was different from 15 g/kg treatment and control group (P<0.05). Accordingly, the addition of aloe vera powder is recommended, especially at a level of 10 g/kg of goldfish diet.
