here's a shot with the lights turned on.
i still need to put together tank hardware, a hardscape and underwater plants, but this gives an impression of how the display will look. i am putting taller crypts all along the rear pane of glass. i hope that these will all grow to around 2X as big as they are now.
i will fill the tank to about 40% of total height--20 gallons or so of water.
i intend to leave the background for the above-water portion of the tank unpainted--the plant forms are nicely silouetted against the white wall.
