Floating Stinging Polyps

[ScubaSteve]

Never timed it really. The hammers were very obvious when they were doing it as they'd start to pinch off the polyp and it'd hang down. Looked like coral cancer or something. Then it'd let go. From my understanding it's a reproductive method. The little pieces are supposedly able to form new polyps. I never kept them around long enough to find out.

Check your parameters and do a water change though just to make sure there isn't something stressing them out. Reproductive methods like that can be a "last ditch effort" to spread itself if it feels under threat (like how aptasia can spread when you attack them).
