Thank you for commenting on my journal, and also for bumping it up, as it had completely disappeared! I agree with your comments on my substrate depth. If I had to do it over I would make it shallower in front. However, as time goes by I'll try to scoop out a bit at a time, and gradually reduce it.
I do like the contortionist vallisneria. It looks nice, and it is interesting to see it send out new plants. If you lived locally, I'd be delighted to give you some. Unfortunately I don't feel able to get into shipping live plants for now. I'm sorry about that.
But thank you for asking.
