baby plate coral?

agreed

look like a baby bubble coral to me.

I agree with the Fungia vote.

touch it, is it hard or soft? if its hard then it for sure looks like a baby plate, if its soft then a baby mushroom perhaps.

From the skeleton I'd say baby Bubble, Frogspawn, or Torch.

If it's the same thing as the other picture....it's a bubble coral.

It is the same...

its not a fungia. fungias wont grow onto an overhang like that. Or exhibit that skeletal structure.

I vote for Bubble coral.

bubble coral for sure.
