That what i thought it was, but i was not positive. Any reason why it turned brown after i trimmed it. Its hard to tell in the picture, but most of it is brown, with very nice green bits near the cut area.
With Cabomba, I prefer to pinch the stems near the substrate. I then trim to the length I want and replant the tops only. I don't have luck with this plant forming multiple branches from a cut stem like Ludwigia or Rotala tend to do.
