Thank for the info!
I have no LMB in the pond. Only 6-9 in HBG. The pond is only about 9 months old. I have looked around the pond but I have never seen any HSB swimming around the edges. This weekend after feeding the HBG's, I thew a cast net and cought 1 HSB. It looked healthy, no fungus, but it looked like it needed a good meal. The HSB have been in the pond for about 3 weeks now.

Thanks again
