I have a 50gal tank that is in need of some plants, and the bottom is a mixture of medium and small gravel. The tank has been set up for over 3 years, and has been running great. I am interested in putting some sword plants in the tank (it's been all rocks up to this point), and am wondering if I will have to pot them in other substrate, or if it is possible to plant things directly in gravel. Thoughts? I have a CO2 actuator on the way. Thanks in advance.
