I recently upgraded my light and got 2 beaded sea anemones online, one came with a torn foot…the other looked ok, but not the best. The one that came with a torn foot, got an infection…and it was really bad. So, in an attempt to save it, I cut it in half so I got most of the infected tissue off it. And I put it under the light in a container with a small amount of iodine. The other anemone looked fine until it randomly started losing tissue…so I put it under the light with a small amount of iodine in the container. (The anemone’s are in separate containers) any ideas on what happened, and what I can do to make sure these guys don’t die?
