I predict the spawning device in 1ft of water will gather more eggs than the device close to the bottom in 3-4ft of water. This is what works well for spotfins so we will see if the behavior holds true for the satinfin shiner.

This article is why the one spawning device is 2-3 inches from the bottom.

Note in the referenced study the water in the pool was only 6" to 7.5" deep (150mm-200mm); so there was not much water depth above the spawning device even though it was placed a couple inches from the bottom.
