I've done plenty of reading on structures and the areas that fathead minnows will choose to spawn. One thing I'm curious about though is when placing structures how far off the bottom do fatheads prefer they be for spawning?

I will be using structures similar to these...

Fathead Spawning Structures

Another question is what sort of items can I use to created the upside down spawning situations that fatheads seem to like. Just turn a shallow bowl upside down on a stake? Gold pans? Looking for something cheap.

My structures will be placed in less than 4' of water near other artificial structure that will provide habitat for the FHM to hide out.
