Hitchhiking Coral ID

[livingstone]

This cute little hitchhiker, on my Vanuatu rock, has about doubled in size in the past four months since I first spotted it. It's nearly one inch across now. Does it look familiar to anyone?

Thanks

That is cool. I have no idea what it is. I looks like it encrusts like a monti, but the polyps look large enough to be some sort of LPS. Not sure.

That looks like a pagada cup to me

Looks like leptastrea to me

I'm probably wrong though, on closer look, the tentacles don't look right.
