NEMO Fisheries in Perry, MO.
Probably 90% of what they sent were RES, but there was a handful of these mixed in. I expected that, and they were too small for my untrained eye to ID with certainty, so I caged them.
If daughter's dog hadn't knocked the cage over it wouldn't have been a problem. I'd have culled the BG/HBG and tossed em in the creek when they got big enough for me to tell them apart.
But now they're in there so I just have to deal with it best I can.
