Does anyone have suggestions for plants to go behind the rocks. I would like to hide the HOB filter, but do you feel like stem plants could detract from the iwagumi-style layout in my tank?
For a first tank, I would say that is one of the best layouts I have seen. It has amazing proportions and focal points. Kudos to you.
I have not worked with it (any plant for that matter haha), but I believe a lot of iwagumis use Vallisneria Nana. You could plant that on each side of your tank behind the rocks.
