keep in mind though, that both the D. Tinc. 'Azureus' and the P. Terribilis 'yellow' will take about 18 months before they are ready to breed, assuming you are purchasing juveniles. if you purchase a confirmed breeding pair, you should have success right from the start. but of course, it is about twice, if not more the cost of 2 juveniles. then also keep in mind that you are going to need multiple insect cultures. besides fruit flies, you'll need to culture springtails and isopods. not only for the breeding tank, but for the tadpoles. and they will eat a LOT of springtails. you'll also need a tadpole station. the terribilis tads can be raised together in groups, but the Tincs will need individual cups, since they are cannibalistic. you'll also need grow out tanks for each species as you go on. it can be VERY overwhelming to say the least!! and not a cheap journey you are planning on taking. not saying you shouldn't do it, just wanted to offer a glimpse of what you are in store for
