I am an avid perennial gardener, but have never attempted a planted aqaurium. I have a 29 gall. community tank and a 55 gallon severum tank. I was wondering if I used only plants that I can attach to rocks and bogwood, will I still need to fertilize them? As my severums get larger, they will begin to dig, so I was thinking of starting out with anubias, etc., that I can attach to the rocks and wood. As you can see, I have no idea how to begin. Shirley
