A Christmas tree without needles will be very adequate substrate for YP to drape their eggs.
John the newly stocked YP are adjusting to the new surroundings and likely feeding on some natural foods. It may take a few weeks and warmer water for them the locate the pellet feeding area. Keep doing what you are doing, the YP will show up at your feeding area.
