I just redid my tank, and bought many more plants. It looks like a jungle in there and it has not even filled in yet. I am not worried about the walls....I think that bushy, ferny walls are nice....but the ground...man. I have begonias, peperomias, amazonicas, ferns, selaginellas, cryptanthus, and more....Will this be a problem eventually? I will pit pics up soon.
Thanks
