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!

Thank you so much! That is really informative and enlighting! I had salt AND fed them a lot of spirulina - so this explains it!! Gonna have to look for a substitute now, no other sinking pellet food available in stupid fish stores here - Tetra products are conquering almost all LFS in the UAE..

if only tetra in your country, can try tetra gold exotic and tetra growth. tetra food is quite powerful for goldfish. if u can find tetrafin gold, give it a try. i not sure the price there, but not a low cost food.
