Four sex ratios (male guppy: female molly:1:1, 1:2, 1:3 and 1:5) at four treatments with three replicates were investigated. After two months production data of the different sex ratios of sex pairing showed that the sex ratio of 1:2 has the higher number of hybrid fry produced (60 pcs) followed by 1:3 (45 pcs) and 1:1 (40 pcs). The least number of fry produced was recorded in the sex ratio of 1:5 (30 pcs). Survival was highest in the sex ratio of 1:2 (100%) followed by 1:1,1:3 and 1:5 with 90% survival, respectively. The color of hybrid in all treatments varies in sex ratio of 1:1 and 1:3, wherein the hybrid color of the fry was white and combination of black and white, respectively. The sex ratio of 1:2 and 1:5 produces the same black color.
