ok clarification please-
About a month or so ago, I posted pics of the same thing and was told by readers here that they were not aptasia, but glass or curly anemones. I have not had a single problem with them. they do move occasionally, but have had no multiplication. I have 2 peppermints in the tank and they casually stroll by them without a sideways glance, and I thought peppermints were their mortal enemy??
