Popping-in to keep tabs on recommendations. I am doing something similar in a 29g tank. Eventually it will be a crabitat for vampire crabs. I have a rough idea what the end result will look like, but still don't have much of a plan for what I will plant, aside from peacock fern, java fern, and java moss...and perhaps some lichen.
