Assuming that Jeffrey D has both male and female YP, he'll need some kind of structure for them to lay their eqg strands on. A more hardy pond weed might suffice.
But this will only occur once the YP are of spawning age/size. I'm guessing that if his YP get to 8-10", he might start to see some egg strands. Maybe next spring 2011, and if not, then most likely spring 2012.
