OK I"m probably going to "tank up" early next year. I have an oscar and a pacu now, but may have to re-home the pacu as he's been harassing the O. Anyway I want to have an aro (black or silver), gar (spotted or Florida), a bichir, a nice-sized cat like a lima, and maybe some more cichlids (severums maybe, something that won't beat up the O). How big of a tank am I looking for with those fish? Of course the whole thing is out the window if the full-grown aro or gar would be big enough to make a meal of the O. I'm thinking I'd need something with at least a 6'x2.5' footprint...

couldn't been said better
