Galaxea astreata
Galaxea astreata is a cluster/colony of Stony corals, and like all corals, they are living animals. When not feeding, they retracted their polyps, showing themselves as hard stony corals. When they are feeding, they display their soft polyps as shown in Pics #1, #2 and #5.
Can you find another Organism they play host to, shown in Pic#4? Clue is in Pic#5
