When I bought some HBG I asked the seller if they would bite swimmers. He said he’d never heard of them biting anyone. Haha! I used to have to wear a shirt to swim. We eliminated as many as we could catch. I can swim without a shirt now, but every now and then I’ll hear a scream.. I don’t think the RES attack like the HBG.
9 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these. I think that's about all I should put in my little pond. Otter attack in 2023
