There are few studies on Symbiotics reproduction effects in ornamental fish, so this study surveys on the effects of artificial Symbiotic Biomin Imbo on fecundity, ovule diameter, GSI and HIS of angle fish (Pterophyllum scalare). This study uses 12 aquaria in 70 × 50 × 30 cm3 for fish with average 10 months age and in abundance of 8 fish per each tank. Fish was distributed absolutely in accident in 4 treatments with triplicates which fed by 4 diets containing 0, 0.6, 1.3 and 2 g/kg of feed for 2 month. Fish fed daily by 5% of body weight feed in 2 times per a day. The reproductive performances of angle fish were statistically estimated. The results showed that the absolute fecundity and GSI of all treatments were more than control ( p< 0.05). The most fecundity was observed in the treatment which fed 1.3 % Biomine Imbo, and the most GSI was observed in the treatment which fed 0.6% Biomin Imbo (P< 0.05).
