I will try update the video: it has better quality.Need a better pic for sure. And the 360L tank seem to be small for an Aro.
Does it say anywhere F1/F2/F3 on the certificate?
Reg lighting, try with Warm White (yellow) T5 tube lights. Just try and see, however this will only give an enhanced looks and light up the existing gold coloration, and cannot do anything to its actual colors. People say good things about Tanning lights/Miracle Lights from Quian Hu, but I don't have personal experience on them.
You can also try with white/blue background for the tank, include some market prawns in his diet and maintain clean water to enhance Golden arowana color. But not sure how much can be turned around, given that it is more than 1 year old.
I am building a bigger tank: 600L.
I will try change the background color and do some experience with the color oh the lamps that I am using.
There are any information about the F1/F2/F3 on the certificate.
Thank you for the tips.
