yellow tang colour

[alexafg]

hi SW guys
i have a yellow tang it changing colour from yellow to whitish
and i have checked the water on saturday at PIU they said everything is good

[gklaw]

Lots of SW fish change colour when frightened.

no one did anything to scare it. i just put some frozen shrimps thats it

Their main diet is algae, if you only feed them mysis they will have a deffiency and not be a healthy yellow, try to feed your tang nori seaweed!

[alexafg]

there is so much alage in my tank and on the rocks

What is your salinity? We have found a connection to Yellow tang coloring and lower salinity. Tend to have better color in higher salinity.

[alexafg]

the salinity is 1.025 SG
do I need to add more salt ? it just happened last night

[Rastapus]

No, thats fine, sounds like diet. If there is a lot of algae in the aquarium, sounds like not the type he likes or it would likely be all gone. Add some snails and feed him Nori seaweed with perhaps a vitamin or garlic extract added to it.

ok IPU thanks

I agree, feed it algae and add some garlic as it could have lateral line disease.. good luck
