Looking really good Joan. I neglected my 3ft and no am struggeling to save my weed. To busy breeding betta. Lol
I found when my tank got to your stage that I thinned out by taking the whole type of plant from the tank. I read somewhere that a harmonious tank should only have a max of three different plants. I was a bit skeptical, but had a go and was really happy once I did this. My main plant is the Java Fern. Then have a a feature plant and say a grass as example.
I think you tank looks great and now the real fun begins. It will never be right, always something to change or do. That's why I love planted tanks.
