BJ Nick. Just an fyi, I stocked HSB 12 years ago. Caught one a few years ago. Restocked again. Caught one of those. I think I remember reading somewhere that HSB are pretty sensitive to some ph levels. I think my pond has one of those ph levels. Our SMB, RES, and Golden Shiners have done well. Our YP have just done ok..

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
Otter attack in 2023.
