Some sort of zoa pest/disease?

[Nazzar]

Hello!

My aquarium has been doing quite well except for 2 zoa colonies that happen to be close-ish to each other.

Now I've noticed this little white/yellowish things on one of my zoa colony.

Does anyone know what this is? Since it also happens to be on polyps that are struggling.

hi,first two look like new polyps?? far right pooping? can you get clearer pics?
@footgal ?

I agree that the far right seems to be pooping. For the ones on the left, I’d remove the growth and call it a day. Maybe do a pest dip just to be safe

Looks like emission of waste, which is not abnormal. This sometimes happens in relation to how they are fed. Target feeding is not a requirement as Zoanthids are photosynthetic. I have found that target feeding Zoanthids always provides mixed results, when a food particle falls onto the polyps.
