Hygrophila corymbosa, it looks quite compact so it might be <"53b">.It’s the 60L on the left
My guess would be that your plant is something else.and will readily form new plants from a single leaf
That sounds fairly definitive, I had no idea you could grow it from leaf cuttings.I have this plant as well, and can confirm loose leaves growing into new plants at random locations in my tank (between java ferns, between mosses, between crypts), so it can regrow from a single leaf.
That’s just for the shrimp/fish and only in one of the tanks. Maybe it makes a difference, I don’t know.You're using a Söchting Mini Oxydator, I wonder if that is improving the tanks growth too?
The moss is great.Couple of pictures of the 37L with the moss growing out of the top.
