Its a low tech with 2 15 watt spiral CF's that has mosses some duckweed ferns and anubias. I'm thinking about getting a med size potted plant to throw in behind some rocks in there. What should I do with a potted plant when I put it in the tank? Leave it in the pot I bought it in? Maybe some sand or gravel from another tank in a clay/plastic pot with a root tab? And any good ideas on the plant? I'm thinking a sword of some kind. The rocks up front are about 6 inches high and the tank is 12 inches tall so I'd like it to fit right in that area with the stems and pot hiding behind the rocks.
