We moved this past weekend, and I seriously downgraded. I've had as many as 24 tanks running at a time. Before moving, I was at 16, and I downgraded so that now I only have 6 - definitely not as much variety as before. There's Talon's tank, Vixen's, the angel tank, my hap/peacock tank, polit/saulosi tank, and my pair of zebra crayfish.
