Hey Bill, where do FHM go during the winter? Seems like they would be vulnerable anywhere in the pond at that time. I get what you are saying about them spawning in a protected zone during the summer, but what about being overeaten during the winter? Would he add habitat for them somewhere during those times too?
I have added 40-60 RBT during winter months, and have no FHM left. However, I have other predators too, but was feeding too. This winter I have added no RBT in order to see if the fry population of some of the other species will be stronger ( -hopefully BG). It will be interesting to find out.
