My favorite is the silver aro. They are the largest, most inexpensive, and easy to find aro. Blacks are expensive and hard to find (at least they are where I live), Jars are too agressive, Africans just look like grass carp to me, and the only way I would ever spend $400+ on a fish would be if it was guaranteed to live for at least thirty years, and Asians are illeagal anyway.
