im trying to decide which tank to get, the VIA-AQUA is bigger but taller, on the other hand the AQUA 40 has a bowfront glass (i like alot), and an internal filter, the VIA-AQUA has a bio-wheel (no nothing about)...which filteration is best? and if anybody has another tank to suggest please feel free (now i hope the poll works becoz i did it before and cant get it to work!)...thanks
