Is that 100 fish minimum, or $100.00 worth of fish minimum? If you're talking 20 fish, then I'd jump on it. But there is no way I would spend $500 on HSB. No way, no how. Maybe you could find a few more people to split the amount?
I've mentioned here before that I think the HBG and HSB combo could work well. However, I have LMB in my HBG pond and so far haven't had any issues with over reproduction. Since I eliminated the pondweed with Whitecap, AND since my water level is down a foot or so, the fry have virtually no escape. I watched the bass hammering yoy LMB last night. And, with the exception of a few individuals, they don't eat pellets, which saves me money and keeps their appetite primed for the job at hand - population control. On themselves, and HBG.
I love hungry, skinny LMB. I think they would eat each other before they would starve. At least, that's what I'm seeing so far...
