ID needed - growth on my zoas

[aranax]

Hi guys. I'm hoping someone can help me ID this thing on my zoo colony. The white stuff looks my oolite sand or they could be eggs. The ID I need is on the bulbous thing that the "sand" is on. It tends to contract if I hit it with the intense light from my ultrabright LED flashlight. It also sweels up to about 1.5x the size in the pic.

Please let me know if any of you guys have any ideas. Thanks.

Sorry for the link but the pic is too big and resizing lost lots of detail.
