ricca matts would look neat !! and I just found out that if I take stargrass and cut it short and keep it trimmed it looks really neat in my 45 as a foreground. your tank is tad smaller, you can also use glosso, or HC< again the HM looks best as a bush IMHO ~ I like it like that ~ you have a great hardscape started !! and the plants will look great show some pics as soon as you get your plants !! ~
