I had 30+ ribbons. I'm assuming something hatched from all those. I have lots of fry swimming along the banks. I can't tell if they are FHM, RES, YP, or GSH though. Walking the banks, I can see lots of spawning beds all around the pond. Could be the HBG too.
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.
