What Did We Play Yesterday?

I feel like an aquarium idler should be right up my alley but this game is boring as shit.

If the fish behaved more like fish (schooling, etc) it would be interesting to watch at least, but as it is, I pop in once or twice a day, sell all my fish, and buy more. And... that's it. You can decorate your tank, and you can upgrade and buy more tanks, but outside watching fish that don't really act like fish there's not much going on here.
