Red butt epoxy ants
Ohiotuber gave me a few of these when I was up in Ohio a while back. I came back and proceeded to clean house with them on my home water, especially on sunny hot days when everything else is getting kind of iffy. I just find an overhanging tree (doesn't even have to be that close to the surface) and chuck it in. Very rarely do the gills ignore them, and I have also had bass, small to medium sized catfish, and carp scarf them up as well. I've been tying them up in size 12-16. I do them in all black and all red as well, and they work, but not as well as the red butt version.
Thanks again, Mike!
If it swims and eats, it'll eat a fly.
