This was mostly a sad, but in retrospect interesting, snorkel. There is much disease among the coral- maybe heat stress because the water is quite warm (need to get a thermometer to take next visit). But the temperature is much warmer than usual and from what I've read, the incidence of heat-stress responses and/or disease is much greater with higher temperatures.
Dying staghorn coral - Acropora cervicornis. All the photos are approximately geo-tagged - the gps was in the boat. Copy the image and look at the EXIF data

Symbiotic relationship - Goby (perhaps Amblyeleotris japonica left) and pistol shrimp (?) (right). This is an interesting symbiotic relationship. The shrimp digs a burrow and share it with one or more Goby. Around sunrise the goby exit the burrow while the prawn does housekeeping - reopening the entrance if it collapsed during the night, and general cleanup. Then at sunset, the goby retreats to the burrow for rest and resovery while the prawn remains outside.
Two Goby serving guard duty for the prawn (inside the burrow). The Gobies also inhabit the burrow. Thus the entrance is Goby-sized instead of prawn sized

Out comes the prawn, cleaning the interior of the burrow
More house cleaning

Need to identify this
Need to identify what is in the middle of the Acropora
Acropora with what appears to be something similar to white band disease
A response to heat-stress?
Need to identify this
Echinopora lamellosa - not healthy while to the right, it seems that the Acropora is healthy

Honeycomb coral
Goniastrea (Honeycomb coral) with some white pox-like regions. Should have been closer

Maybe white band disease?
This was interesting and I don't know what it is

These appear different from the white banded bleached regions
