Picked up a random piece of zoas, thinking of putting it in another position and found these inside and around some polyps that's not doing well.

think they might be sundial egg sac???

Thanks! Me think so too. It seems to be eating the zoas from the inside.

Some photos of sundial snails, courtesy of zoaID.com. It shows various types, some with pattern and some not. Perhaps yours is another variation of sundial snail...?

Not sure if it's sundial, cos I've seen them b4, and the shell is hard. But this one is soft.... Think will have to do a couple more rounds of spring cleaning again.

Do they propagate fast ?

Sigh... that's the price to pay for keeping zoas... lots of pests to handle. I'm currently still battling nudis myself.

I'm not sure about that because I've never seen them in my tank. Definitely nudis will top the list of zoas pests in terms of propagation...
