I've got them as well. They seem to be most abundant on a zoo rock I got from a store here in Nanaimo. They just go crazy on that rock, hardly any room for the zoos so I pick them off of that rock more often. They're all over the tank though and are the first thing people get excited about in the tank "ooh is that a marble?"
I just pick them out when they get really large and covered in coralline.
Summer tank temp: 79@night, 84@day
Non-summer tank temp: 79@ night 82@ day
I secretly like them
