My only question is do you have to tear down the upper gravel and plants every time your peat stops working? I don't see how you can get away from this. > > > I've been thinking about tank depth.

My next tank set-up may be influenced by > your results. One of my favorite breeding tanks for pairs and trios of small smaller species are some hamster tanks (16x18x10"h / 40x45x25cm h). I keep 1 - 2" of coarse sand in the bottom. I've never had problems breeding fish in these.
