I am a bit conflicted. I did add rock structures before the pond filled to provide SMB spawning sites because I do not want to keep stocking, but more predators means smaller predators. My issues are knowing what numbers of each species and their sizes, and also how that interacts with the available cover to affect future fish population dynamics. There are a lot of variables even if one understands the basic principles. I guess the uncertainty and the prospects of experimenting are part of the fun for me. Having a place to pick the brains of experts and discuss issues makes it a whole lot of fun.
