If it were me, I'd try most for the fire, cause I like those more, and I want combos with them. I love the black eyed lucy. However, I'd likely cycle the mojo and spider with at least one of the females.

As for getting more females, I'd only recommend that if you have the room for a lot of clutches and babies. If the males are good breeders, you could likely pair them each with 6 females. So you could easily have 18 clutches, but that's a lot to start out with...

It really depends on what you want to work towards. Fire and fire crosses? Mojos and mojo crosses, or spider and spider crosses. If you're trying to combine your fire, mojo, and spider, then you need to breed each male to the females to try for the female morph of each.

Good luck, and enjoy.
