Fish color loss

[TheRockPlayz]

I’ve just put my fish in color loss about 1 day ago and they are losing their color now? The water conditions are perfect on every everything I can check, salinity 1.025spg, temp is 78 + or - 1 degree, no ammonia, nitrite or nitrate. They are still eating like normal and there is no visible ick anymore although my hippo tang has color loss on her belly and my clownfish (normallly black aside from the face) is orangish

The lighting is bad because this is a fast set up quarantine tank, their normal tank is a 20.5g whereas this tank is 5.5g.

I’m worried that this tank will stress them out more than it will help them.
Any tips or info to make them more comfortable during quarantine will be helpful!

Really cant see much due to the dark lighting. Please post again using bright white lighting, no blue

Here’s some more photos, the water is slightly blue due to copper treatment

So they had ich and you have had them in copper for 1 day? Copper treatment for ich is a 30 day treatment at copper at 2.25 ppm.

they have no hiding spots and are being treated with medicine, they are stressed and the colors reflect that

 

[dedragon]

large pvc pipes and elbows and t junctions* can be used to give them spots to hide

You and me both!

FYI, copper can be very toxic to fish. What copper treatment are you using and how are you measuring the concentration in the tank?

Are you testing for ammonia?

I would add some water movement and an airstone, the water looks stagnant IMO

Welcome to Reef2Reef!

Copper treatments don’t cause the water to become blue, what is the brand name of the product you are using?

I would not worry about color loss in a quarantine tank. Can you post a video from YouTube - I can't see it. I wouldn't worry about 'stress' as compared to disease - are you treating them with medication? (You say there is no ich 'anymore' = does that mean there was ich before - did you treat it?
