Eh. I think you could do 2. Isn't that what you wanted?
When my cuzzies saw my tanks- they flipped. They saw the Betta's 3Gs- and they were like 'WTF?! You wasted it on a dumb betta!? You could have like 3 or 4 cool tropical fish!'
And then they saw my 10G, and told me how much of a waste keeping Goldies is. And a bunch of other crap.
