@AvidD The substrate consistes of fluorite, topsoil, then sand. I was unaware you're not supposed to "cap off" fluorite. Why is that?

The plants in the back left corner is what my LFS called alternauthera rosaefolia. I looked it up, but didn't find much on it.
All i know about them is what my LFS told me: it's a background plant.
