need a little help

What island is it that the angelfish turn into a color morph? That if moved from they lose the morph.

 

[Calappidae]

Do you by chance mean when they change color from age? Certain angelfish, and some tangs as juviniles look completely different.. as they grow up they will change into what some thought to be a completely different species of fish when adults. Emperor angels are the most well known for this behavior.

I think he's talking about diet related color changes, not sure the location he's looking for though.
