Purple tang issue

[Benhuan]

Hi all,
I have had this purple for about 2 months now he ate Mysis and nori almost everyday. However last week and a half he has stopped eating Mysis and now he takes one or two bites of nori and leaves. My dt is currently in hypo and my other tangs are all acting fine. Now my purple is losing colours on his fins. Can someone help id what’s wrong with my boy

What is salinity and water temperature?
Have you switched salt mix?

is its poop normal or white?

other foods to feed:
Small plankton
Formula 2 flake and frozen
LRS herbivore diet
Spirulina brine shrimp

ADD GARLIC EXTRACT AND LIQUID VITAMINS 2-3x a week to food

The very low salinity may be part of the reason for this. Go to at least 1.019
