Growth on zoa never seen before.

So i got few zoa from someone and one has struggled to open 90% of the time. Its isolated from the rest and has these little hairs on the stalk. Wondering anyone is familiar. TIA

Did you do a dip? It might be some weird fungi infection.

Few threads on these, think the consensus is hydroids and a mild hydrogen peroxide dip usually takes care of it. Are these ones from me?
