Juvenile Bigeye Emperors have bold markings, which gradually fade and disappear entirely in adults, to be replaced by some yellow tinges.
These large fish are notable for their ability to hang motionless in the water, often in large groups.

Indeed the adult does look solemn – though beautifully lit, it looks sad and somehow plaintive!

The adults have great gravitas, but there solemn demeanor is actually cover for their hunting. Their prey is invertebrates in the sand, which they can see from a great distance. Since they hunt mostly at night, I haven’t seen one swoop down to grab something.

They are rather cool looking fish. The ability to stay still is amazing

Certainly the most solemn-looking fish I see around here, a look enhanced by their stillness.
