Powder blue tang white spot

[Alexblade1889]

Hi there
I noticed that my salinity had risen to 1.030 yesterday so I started to bring it down and got it to 1.026/7 I just come home from work to find my powder blue tang like this I was wondering if it was the salinity that’s caused him stressed and this is white spot that’s developed or could these be burns from the high salt levels

He has been doing sometimes not all the time I think he’s trying to scratch on the sand I haven’t seen him flash against the rocks yet I’ve only been in a hour or so

This looks like lymphocystis and associated with water quality and diet
Assure your water tests do not show elevated ammonia or nitrate and provide minimum of following foods:

spirulina brine shrimp
Nori seaweed basted with garlic extract
Mysis shrimp
Small plankton
Formula 2 flake and frozen
LRS herbivore diet

Add garlic extract and selcon vitamins to the foods 2-3x per week

Minimum, meaning feed at least those foods
