I found these plants in my pond, I was wondering if you guys could give a ID of the them. Thinks for the help



I think the above plants are pearl weed. is that right?


Is this a kind of Hydro if so which one?

I have done some research and I think know what kind of Hydro this is. Does Hygrophila polysperma or Dwarf Hydro sound right?
