Coraline and liverock vs. temperature!

[Sir Patrick]

What temperature range can/will coraline survive at? How about live rock, and remaine alive?

Been wondering this for a very long time......

Corallines live in varying depths of water, ranging from periodically-exposed intertidal settings to 270 m water depth (around the maximum penetration of light).Corallines, especially encrusting forms, are slow growers, and expand by 0.1 to 80 mm annually.
