Im in the preparation stage of my waterbox 180.5 build and am wondering which tangs I can have for a couple of years if bought small. My first and "must have" if you will is an Achilles, followed by in order of preference of course, Powder Blue, Purple, Yellow, Hippo, Yellow eye cole. I will be able to trade them out for younger /smaller of the same with my LFS ideally after they grow to a certain size. Im not looking for tang police reports and am wondering if the first four would be possible if all introduced after the other fish and at the same time as each other.
