Check out liveaquaria.com, they have a nice selection of plants including Dwarf hairgrass....I've got a 10 planted with a selection of plants i got from Pet Smart that look pretty good...im also thinkin bout adding some DH as well to get that bottom of a pond look. As for fish I have 6 Rainbow sharks, 6 Tiger barbs and a Green Spotted Puffer and they get along great.
