I needed to move a 50 gallon tank to prep a room for renovation, so I took a few representative plants from the tank for safekeeping, and planted them in pots, which I placed into a 30 gallon tank with no stubstrate. After I got it all set up, I realized that it looks pretty good. So, now I am planning to renovate my aquatic frog tank, using minimal substrate, and potted plants. After seeing your setup, I decided to use smaller pots, and perhaps even decorate the pots in some way. Thanks for the inspiration.
