I'm gonna be remodelling my 9G Eheim Cube and I'm looking for recommendations for a good background plant that isn't a stem plant. The water column is just a little less than 30cm (or 1 foot) and this is a low to medium tech tank. Stem plants have proven to be to much of a pain with the trimming and the loss of leaves when I forget to fertilize regularly. I've tried Vallisneria (one of the shorter corkscrew varieties ... unfortunately I don't recall the exact scientific name) however it never got more than 6 inches tall. I might try looking for another val species to try but I'm also looking for other suggestions to consider.
