It also depends upon where the tank is located. If the tanks are in a frog room, they tend to be more simple, but you will notice that the tanks in many long time froggers that are located in the living areas of their home, these tanks are often larger and more complicated, ie. more beautiful.Lol...that's probably true. But you'll also probably notice the longer someones in the hobby the less complicated their tank designs are. You often wont see the waterfalls and ponds because they do take up the floor space. The tank design should really be for the frog....but if you are going to design it for you and the frog you better go bigger.
