The only one of those 3 I have have ever had was cabomba, all I did with it was top it and put the head back in the substrate and let it grow back up, sometimes I would cut off just one node after it split and replant it tell the other got taller too. But I found in my tank anyway, if i left the bottom planted to long it eventually got stringy and broke up. I only used it to establish my planted tank, as it took a ton of work as it grows extremely fast.
