There's nothing dwarf about dwarf sags. If you give them light (about 4 w/gal), they will grow out of the tank. If you keep your light low, they will be much easier to control. Lobelia cardinalis is good choice up front. When they get higher than you like, pinch it off and plant your cropping. You don't need much of this to get a stand started. Cryptocoryne lucens is also a good choice but it is much slower growing,
