Frogspawn Coral Field Guide
“Frogspawn coral” is a trade name for Euphyllia-group corals whose tentacles often divide into rounded tips. This profile uses Euphyllia paradivisa as a cited reference point—not a guarantee every photographed frogspawn is that species.
In the wild
Corals of the World records Euphyllia paradivisa in Indo-Pacific ecoregions and not in the Atlantic. That is species context only, not the collection location, culture history, or age of a customer’s coral.
In your reef
Plan around expanded tissue, protect nearby corals from contact, and use dated photos to track changes rather than a trade-name color label.
- Placement: Give it room based on fully expanded tissue—not just the skeleton.
- Spacing: A new frag’s reach is not its mature reach.
- Record the real history: Add acquired date, source when documented, placement, and dated growth photos to Coral Passport.
What this guide will not guess
A species-level Indo-Pacific range is not proof that a specific coral is Australian, Indonesian, wild-collected, aquacultured, or a particular age. Those details belong in a Passport only when documented.
