White spot on Zoa (Help)

Luke Crabwalker · Jun 1, 2023

These zoas have a few heads not opening, noticed this large white lump on it. Tried blowing it off but its latched on or stuck in the coral. Any ideas?

does it move around on Zoa? What are your tank mates

No it doesn't move, but I thought I saw some goo coming out of it earlier. Couldn't tell though.

Tank mates are a YWG and a pistol shrimp, along with other zoas and GSP, and other small cleanup

Sorry to revive an old thread, but did you ever find out what this is? And did the zoa end up being okay? I have something that looks nearly identical on my zoa, and your pic is the only one I've found that matches.
