Digging by tail sweeping really picking up. The male NBG is not keeping the bratty HpBG clear of nest site. They are "vent presenting" at each other. Something is up.
Hand-paint Bluegill I have limited experience with where complex social interactions possible. Most mating I have done with them were pair wise. It is likely something new is going to be seen with this. Based on what Coppernose Bluegill from the St. Johns River basin do, we can extrapolate from Northern Bluegill too much.
My hope is I got the sex wrong on one of the HpBG.
