nocturnal pest anemone

[Alberta-newb]

Tagging along, I've got a couple of these as well and are nocturnal as you have described. Would love to learn more about them. They haven't spread so far (1 year since I set up) and don't seem to be an issue. Not saying they aren't a pest as I also have one mojano that only split into two in the same period....not a pest yet, but they're going out this week anyway just to be safe
