Whats going on??
In the morning when the lights are on the fish are totaly fine and colorful. But when I get home or later when I look at the tank when the lights are out the fish are all pale. So I turn on the light and they are pale and I was not imagining things.
I tested the water and its at 0 Nitrites and 0 Ammonia.
There is areation going and I turned it up at night.
I use a 2026 Eheim Pro II media is 2 filter pad , Ehfimech and Ehfisubstrat.
I use no CO2 [yet], its planted and not overstocked.
As for chlorine remover I use Stress Coat.
What could be causing my fish to become pale when the lights go out?
What could I try to fix thei [my pearl gourami and kuhlis look like ghosts]
could I try a different media type in the canister to fix it maybe?
