So I'm going to be buying some HSB for my 1/4 pond. I haven't confirmed yet, but I'm 95%+ sure that they're pellet trained fish.

That's fine because come spring I'll be turning the feeders back on. My question is, should I stock them now?

My pond is just about to be fully iced over and I wouldn't normally hesitate to stock a bass/bg at this point in time, but I'm not sure about the HSB.

I'm assuming they'll go into hibernation mode as well, but I really don't know and I'm just guessing. What are the chances they'd over winter well?
