I hear you on the background - but as mentioned by Sawyer1206 it actually is a "room divider." It doesn't make for great photos, but it does mean it can be viewed from the couch/living area on one side or the entrance/dining room on the other. Also, we are mostly out during the day, so light coming through is less of an issue at night...
Some bigger fishies and a proper CO2 tank to really ramp up the greens (which will effectively provide a bit more of a "background" from both sides are being added over the coming months...will update...
