From the video, the color of those spots look quite similar to your soil color... maybe they are just broken-down soil particles that got circulated around the tank and settled on the rock surface?

I have the same thought too.
So I went to scrub it off. To my surprise, it formed back again.
I did not see any particles floating around, neither do I see the substrate moved by the water current, so kinda puzzled if it's the soil. So I thought it could be algae or something else.
it's good to hear that it's not algae on the first look, I'll leave it and keep monitor.
Thank you once again for the insight.

My guess should be particles of soil. You have livestocks and current in the water that is pushing the particles around? I have a similar rock and it sometimes have debris on the surface due to fishes and hangon waterfall current
Do you have any of those wood that have plants tied on them from LFS and shrimps together?
my shrimps like to chew on those and the gravel will have lots of there when I do WC
I would think that it is the soil particles. However, algae can form on the small cracks in the rocks too. If its algae then just throw some shrimps in there? Haha, well I guess if you want to confirm you can stick your hand in there and feel if the rock is slippery. Slippery = algae I guess
That shit Cray!
