Forum:Ancient Fish and Carbalite

Ave, my name is Chris and I record me only now, but I already knew this site, and very often i visit it. Sorry for my English, maybe i wrote something wrong. So, i want to ask you if someone now how i can find the "Pesce Antico", probably "Ancient Fish" and the Carbalite Minerals. I read than Carbalite Minerals are G-Rank materials... does it mean that i can find it only when I will start the High-level mission? When i can start them? I have done all 4 star mission an about all the 5 star with the Elder, but i haven't the Second "Grado Cacciatore", in English maybe Hunter Grade or something similar. And about Ancient Fish I haven't found anything.

Thanks for your answer.
