They are larger than zoas. I think they are blue palys? Grow like weeds and take over everything but star polyps! I will try to get out the floating ones they are stillZoas or Palys? Are they under 3/8" each?
Theg don't look like palys from the picture.
Zoas shouldn't be a problem.
Just siphon the free floating ones out and flush them down the toilet.
Attached but look like about to fall off. We have frequently found them on the sand bed growing. Thank you very much.
