The Joes Juice did/and didn't make them spread. Like all anemones' when in mortal danger, they split. They try to survive. If they aren't totally killed, they split, and return in numbers. And...they are tough to kill. When I use Joes Juice, I let it eat, then check back later on that day, and check for a week. I see ANY of the anemone starting to return or any feeding tentacles, I nuke it again. The Pepermint Shrimp will only eat the smaller ones, sometimes. Plus, if you feed your tank well, they won't touch them.
All things good, for our corals, are good for these pests also. They are the weeds in our front lawn. Hope you get rid of them, your tank is beautiful.
