I currently have a Juwel Korall 60, which is just under 15 gallons. The equipment is just the equipment that came with the tank.
Read as many books and websites as possible. Ask questions on fish keeping forums if you are not sure. There is a lot of knowledge out there to help you.
Currently: 4 long-fin zebra danios, 5

Not sure of the plant names, but I have two planted bogwood creations from a lfs and some plants that look like lillies planted in the foreground.
I have had a fish tank for 10 months now. I started with the Fluval Edge, which was much too small for any fish I wanted to keep. I have had my current tank for 7 months, and am much happier with it. As soon as I get a bigger place to live, I know I will end up with a bigger fish tank.
