My 5.5 planted tank is standard gravel, driftwood, anubias, java fern, and java moss, and a breeding colony of cherry shrimp.
All of the plants do great with low/moderate light, and the shrimp love to nibble on algae.
I've got a dirt-magnet jr. style sponge filter in there, but more for the infusoria I hope it will provide the little shrimplets
Since this is in my office at work, its under a flo. strip light about a foot over the tank - this allows me to have pothos growing out of the tank and across the desk (and up the cubical walls, and across my neighbors cube - its taking over the whole office ! )
I figure the pothos is my biggest form of nutrient export, and the roots make a nice background (the shrimp love to climb them).
Very low maint tank - I try to take out a gallon of water once a week, and replace with dechlorinated room-temp tap water. I also add about a gallon during the week - the pothos drinks alot of water !
The tank isn't heated, and stays about 72 - perfect for the shrimp, just warm enough to breed but not warm enough to breed too quickly and overwelm the tank.
No other additives.
It certainly my simplest tank, and easiest to maintain - and other than people who ask "where's the fish" because they just can't grasp that not all aquariums are "fish tanks" - it gets rave reviews from my co-workers
