IMO the YP will not lay eggs until the water temperature stabilizes near 47F-50F. Keep the ends of your tree-shrub branches at the bottom of the water visibility range so you see all of the first egg ribbons. Take, record, and report the surface water temperature when you see the first egg ribbon.

Don't expect very many of your species of fish to actively feed at the surface until the water reaches 50F-55F. A few may take a little feed at 45-50F.
