I would go 1.1 pastels and everything else females.... 1 male can easily breed 3 females, you could have
normals
pastels
super pastels
spiders
bee's
fire
and firefly's
from there you have more options..... keep a firefly and breed to spider femalse. keep male bee breed to female pastel ect..... you can do wicked things with that set up. That is what i would do
