I love sand substrata, it will look great when it's all done, I am not up on plant names but it would look better with real plants (small)if you decide not to put real plants in you may as well take some of the sand out to about 1.5" give more room for the fish,.....here is my small 16 gallon tank
Hi Brian, the java fern should be planted on wood or rocks/stones, not in the substrate as it will rot and die.
The tank looks lovely
