do you have any aggression issues bagu??
the L.Brasiliensis may struggle, and the blyxa can be hard although it does respond well too easycarbo dosing. It may melt intially too as it doesnt travel well. Apart from that everything sounds fine.
I have never heard of Crassula Helmsii, but looking at the picture it looks aquatic.
