I set this tank up on my desk at work recently. It's a 5 gallon Fluval Chi, dimensions are 10" x 10" x 12.3". It uses a very low watt LED array for lighting and filter pads for filtration. The fountain on top provides a decent amount of surface agitation.
I added a 50w titanium heater since we keep our office chilly (tank was 66 degrees the other morning, according to the thermo).

I finally added some live plants as well as a few cardinal tetras. The plants are two anubias nana and one java fern, both low light plants attached to driftwood. One of the anubias has been in there for over a week and the roots are starting to grow and grab onto the driftwood. I am lightly dosing Seachem Flourish with each water change and depending on how the plants do, I may or may not add some supplementary LED lights. I am currently doing 1 gallon water changes on Mondays and Fridays and if need be with the livestock I'll add in Wednesdays, but so far so good.

I hope to add a couple of shrimp (possibly cherry or red crystals) and an Otocinclus soon.
