White spot on Zoa (Help)

[Luke Crabwalker]

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
