but its interesting to note the reefs off Kuwait in the dead end of the Persian gulf didnt start bleaching until the waters got up to 95 F.

Interesting to know, as we were all discussing our tank temps, and what is the best temp to grow corals.
maybe we needs some persian gulf hybrids. but im not sure they export, as doesnt Thailand.
