Since BoSoxFan is asking questions about plants, may I add a question of my own that may also benefit BSF?
I hear that duck weed plant is good for fry and eggs protection and also nutrients. I couldnt find any duck weed so bought two bunches of frill plant. I tied the ends up in a small elastic band and have them floating on top of the water.
My question is this:
Can Frill Plant be left to float the top of the tank without being rooted and survive? My lighting is the standard lighting that comes with tank hoods, and figure that by placing the plant on the surface of the water, #1 It will be closer to the light . #2 protection for eggs and fry.
Any thoughts on this, if its a good idea?
