Difficult to say. There is so little of it to see

Sorry, this is such a tiny amount of growth. You would likely need to get the sand grains under a microscope to ID the organism coloring the sand.

doesn't look like Dino's to me. maybe some diatoms or cyano. hard to tell though.

Ok can i have some diatoms after 5 month? i already had the ugly stage in my tank

i wouldn't worry. tank is still building biodiversity so phases can come and go. silicates feed diatoms so maybe you have a little imbalance but i wouldn't worry. see if you can ride it out. if it persists then run an ICP test to see where your silicates are at. if high maybe the source water is elevated.
