Name this coral?

[SeaHorse_Fanatic]

Pure white lps (unfortunately) tend to be coloured corals that lost their symbiotic algae (zooxanthellae). Hopefully this is NOT the case for your coral.

It's strange it doesn't have the tips/feathers off the polyp like alveopora but it looks the same closed up.

If this has lost its colour does that mean I bought a sick coral? Or it's going to die?
