this one is called the regal tang, also known as hippo tang, and is characterized by its contrasting black and almost neon blue colours. the tail of this species is marked by a bright yellow wedge and can grow to about 10 inches long. they are a shy algae eater fishes. (from sea and sky magazine)
this should've been yesterday's colour, and yesterday's colour should have been today's. but since today's colour was posted yesterday, yesterday's colour will need to be posted today. huh?
great colours and find - and I think you've confused us all now, but I think I get it, your picture from yesterday was indigo jellyfish for the worldwide minute, and this shot, taken a few minutes before is blue, so they should go up in a different order
hahahaha
great fish
