I would get you hands on frank’s aipsasia killer. Well worth the 15 bucks. Pull the Duncan out and doctor the stinging dudes. Be careful not to get any on the Duncan headsI do have Aiptasia X. Is that safe to use that close to a coral?
As far as pull it out and super glue, won't I kill the heads of the coral that come out of the water? I mean those heads are pretty close to dead already i think.
Sorry I'm not very experienced with corals.
