caulastraea

So I have this monster candy cane colony. They started as 2 heads 2 ish years ago. I’ve found that the smaller heads beneath the large mass of the colony are losing tissue and receding. It’s really only like 2-3 heads. And they don’t get any light because of the sheer mass of the colony. Is this...

This is going to be a really stupid question but as my candy canes split should they tissue cover the entire skeleton or just about an inch below each head? They’re around 50 heads now and the tissue doesn’t cover anything but between heads that are close together and about an inch below each...

My name says zoa fanatic but candy canes are my passion. Anyone else love this coral? How big is your colony?

Today I noticed slime oozing from these spiked protrusions on my Caulastraea. They seem to extend and retract. I can’t seem to find them on anatomy diagrams and such. What are these protrusions?
