Slowly building a tank that was pest free. Got a zoo colony from swf. Inspected and nothing. Placed in tank and zoas finally opened up and looked nice. Did a night check tonight and saw 3 weird little filaments floating right above the closed polyps... weird so I get looking from every angle I can and sure enough 3 teeny, tiny, baby aiptasia so small they were unseeable between the polyps.
My predicament is how to kill these mini anemones... can't cover with paste, and can't boil them. Either method will kill the zoas clustered around them.
