good luck with you're clean babies.
i've been lucky to be able to breed from wildcaught lines, so i can breed my own F1. and last few years i even sold some F1 to some good breeders in the States.
so my advice, keep them clean, but don't inbreed them, these probable are related, so try to get an old line, from as far away from them as you can.
i started my bloodlines from 2 wildcaughtgroups, wich i handpicked from a shipment, the day after they arrived.
and was smart enough to pick extra males, so now i can breed the babies from both groups, with unrelated males.
i also breed with the fasciolates, and also sold some F1 to the states, but kept most of them for myself, while they did some amazing stuff with them, same goes for the afghanicus
i do this with al the gecko species that i breed, even with the fattails, i breed CB X wildcaught, and the same goes for the paroedura picta. and some other species.
i also do the colourmorphs, but my basics are simple, keep track of your lines, and try to keep them unrelated.
