So I have a 150 gallon 4x2x30 with african cichlids. I just got a 240 6 x 2 x 30 that I was going to move said cichlids into. Being that the 150 isn't overstocked my thought is leaving it alone and putting something else in the 240. I won't be able to upgrade from the 240 for a few years, so what would be good in there long term? Since I have african cichlids already I'd like something else, so someone talk me out of an Oscar tank, or that's what it will end up being
