"pearl" bubble (Physogyra) coral isn't the same as "bubble" (Plerogyra) coral.
Plerogyra (bubble/grape coral) is probably my favorite coral.
I don't care much at all for Cynarina or Scolymia![]()
I've seen bubbles take wandering bristleworms. Bubble corals have a sting that ranks up there with the most potent of anemones IME/IMO. I love how bubble corals can puff out their vesicles and deflate to nothing. They can recover miraculously from a small piece of dead looking flesh. They can be fragged rather easily. Their skeleton is incredible looking, too.I am of the opinion that they can be lethal to smaller fishes. I believe that a large bubble was responsible for the dissappearance of a scooter blenny I was keeping at the same time. I used to feed the bubble full silversides and was amazed at how tightly it contracted onto them as it ingested them. Any thoughts?
