wow... Is that really from the Philippines? I'm filipino myself and own 2 3 inch flower horns.. got them from bio research. Anyway, where did you get fish of that QUALITY?... most I find are discolored, etc..
yup, it's all in the genes. also, you dont get a 100% probability that you'll get large kok fry if you pair a male & a female FHs with large koks. only a small percentage would come out with large koks.
