How To Increase/maintain The Black? Options

[Hamad]

I'm noticing the black is fading to more silver-ish with metalic shine instead of deep black on my adult orandas, they used to be darker.

Is there anything special to do beside sunlight that could maintain the color? I'm feeding JBL sinking pellets with 10% spirulina which supposably enhances color.

They eat very well and very lively and I change the water [80% every 2 days]. Also indirect sunlight is there during the day so I hope there's something to do!

Thanks!

Dear Hamad

Perhaps this thread will enlighten you on your blacks and your feeding of high content of spirulina

Blacks are especially hard to maintain in terms of coloration
As such they are recommended to be kept by themselves if color enhancing food are required by other coloration breed.They are sensitive to the environment as well.A dark base floor and surrounding will deter color lost compare to clear glass tank and white or lighter based floor.It is also sensitive to salt content in the water which may rectify chromatophores listless in its presentation.If the fish are not in the pink of health,the blacks will be listless,showing more reflective gold and pale shade looking.
