What are some good, low maintenance plants for a 55g Apistogramma tank? I plan on redoing the tank in February, and want to make it planted. I've already got water lettuce, java moss, moss balls, and duckweed that came with the water lettuce. Aside from the Apistogramma the tank will also have guppies, a bn pleco, and glowlight tetras. I've already got driftwood, and would like the tank to look natural.
