Answer
Hi Teaghan,

One adaptation is the colors they have developed.  Bright colors, to other wild fish, often denote a poisonous fish.  So, this is a defense mechanism.  By adapting to its environment, developing bright colors and a yellow tail, they stave off predators much better.

As it grows, it changes colors.  

As a juvenile, the Emperor is born with what look like rings by the 2nd half of the body.  Know why?  It looks like a big eye to a predator, who would bite the tail instead of the head, giving the fish a chance to survive and get away by running away from the predator as it goes for the rear.  If a predator goes for the front, the fish often can't escape.

I don't want to give you the answers, so I'd like you to continue reading at http://www.fishchannel.com/saltwater-aquariums/species-info/angelfish/marine-ang...

But, those are some things I know, that are not published.

Happy fish-keeping and writing!
