Thanks, those bulbs are real slow growers, and if nitrate is kept at a decent level for the fish, the plant doesn't grow but at a snails pace. One bulb is really pushing the roots right now, but only has an inch or so of green growth, not sure if the fish are eating it as it grows or if it is just staying that small, lol. I am looking to get some already started ferns, as the bulbs do take too long to grow.
