Here is my 15 gal set up. Has been running for a while, just added driftwood and more plants today, took out a plastic plant, added the river stones. I know it isn't as nice as most of the tanks on here, but its my first try with a planted tank. The java fern and boblitis are attached to the wood with fishing line. I hope they attach and everything grows well. Added some api liquid fert, hopefully I can add some root tabs later (they were sold out). Any tips or tricks? The ball of moss from petco (moss on a ping pong ball or foam ball)....will it live like that or does it need attached to something?
