Representative Bubble coralphoto — a dedicated image of this exact morph isn't available yet.
A teardrop-bubble form where each vesicle is more convoluted and lobed than the round bubbles of *P. sinuosa*, with small pointed outgrowths giving a more textured look. Colors run brown through gray-green to blue.
📜 Backstory
Long traded as 'Octo-Bubble' or 'Octobubble' and historically sold under the genus *Physogyra* (*P. lichtensteini*). The classic octo-bubble was formally described as *Plerogyra diabolotus* by Ditlev in 2003, a name that only gained traction in the hobby after a 2019 Reef Builders article ('The Classic Octo-Bubble Coral Finally has a Name'); it is also marketed as the 'Devil's Bubble Coral.' Offered by FreshMarine, Blue Zoo Aquatics, and others, and discussed across Ultimate Reef and reef2reef. Lineage is wild Indo-Pacific collection (commonly southern Sulawesi), not a named designer piece.
Keeper tips for this variant
Treat like other bubbles — shaded-to-moderate light and weak, indirect flow — but handle with extra care, as the skeleton beneath carries thin, sharp projections that snap and that can tear the tissue if the coral is bumped or moved while deflated.
