REx, Thanks for the thoughts. I have seen that in the past as well, but the FHM dont head down deep unless they have to in my pond due to the big guys being there.
Sunil, Last year was first year of spawn for SMB. I am not sure if any made it past fry stage as we went into major drought right after they spawned. I was thinking it may be time to cull but not sure at the moment.
