[BadRoma1]

:huh: what are those pink bumps or pimples pop up on top of some bubbles on my bubble coral? does this mean that he has too much light or not enogh? is this a sign of anything at all?

Are you sure it's not an pearl/octo-bubble coral?

actualy, that is what some of my bubbles look like. but only few bubbles, not all, like on a second coral.

A regular bubble coral (Plerogyra sinuosa) has larger individual polyp sacs (the "bubbles") than octo-bubble corals (Phsyogyra sp.) tend to have.

I wouldn't worry too much unless you see a lack of polyp extension or skeleton deterioration.

Just continue with good bubble husbandry: low flow, med. light and target feeding of meaty foods every few days.
