Well, here's a pic of my 20L tank setup for my @3 month old:



Cypress bedding, UTH on each side (only hot side in use now) attached to Johnson t-stat, accurite digital thermometer with probe under hot side, separate digital thermo with probe under cool hide, two identical hides, and the branches and vines cause my girl also loves to climb and is surprisingly good at it. Oh, and the screen top is set up as in the sticky. Also, those lamps are 25W bulbs and far above the tank for lighting only. Heat comes from the UTH.
