The Anthias didn't survive the night. At 3:30 am it was already lying upside down on the substrate, gills flared completely open as well as his mouth. I've got no idea why this fish didn't make it. This is so sad. I took that lifeless fish and gave it to the larger rock anemone, who ate it within a minute. Waste not, want not. 

I found six more baby whelks, about 1/8" long, 1/16" wide. I used tweezers to pull them out.
