Atlantic blue tang turned yellow

[BattleReefer]

I picked up an Atlantic blue tang that already had its adult coloration in my previous 45G tank, transferred it to my new tank within a few months. About 2 months after being in my new tank (display around 150G) it reverted back to its yellowish juvenile colors. It eats extremely well and shows zero signs of stress, basically runs the tank. Only fish that’s bigger is the Naso which doesn’t bother anyone. It’s been in this form for about 4 months. Water parameters are fine, it’s a SPS dominant reef. Anyone experience anything like this? While diving in the Virgin Islands I did see some of these with similar coloration, but most exhibited the dark blue we generally see.

Anyone experience anything like this? Like I said, fish is perfectly healthy, as well as the rest of the tank so I’m not looking for drastic measures. It’s just strange and curious if it’s something the tank might be contributing to. Picture below shows the tang. It’s probably 4-5” long currently.

Cool! I’ve had Atlantic blue tangs fade to a light blue/yellow, but never turn full yellow like that!
