The Pogostemon helferi pushed out the HC (grew over it + some HC which became too tick floated up).
Photo taken after I removed the P. helferi mountain ;-);
Later on I took the Hygro Rosanervig out and planted Hygro difformis instead. I also added a few stems of Alternanthera reinecki (red plant). Acicularis grass and P.helferi became the main foreground plants, accompanied with some Blyxa japonica and a strange carnivorous plant Utricularia sp.
