Thanks. The crypt takes much space, I agree, that's why I trimmed it well and it looks much nicer now

, but the tank is still not ready for photographs. This is my plan: (sorry but this is a quick drawing..)
That foreground plant is Java Moss, not grass, and the red plant in the middle is a lily ( already in the tank..).
Any ideas for this plan of mine is very welcome, but note that not all plants are available where I live
