Is there a way to tell them apart when they are young? I have seen this gorgeous jardini/leichardti looking fish (assumed from the pics i have seen here) and i am wondering if its a jardini or a leichardti. the LFS i went to called it a austrailian arowana, which is probably a jardini. So... the question is, how can i tell? do i look at the barbels? Different markings compared to a juvenile jardini? which is which?
