Tiny dots of greens on glass of tank

[yuji]

On closer look, I can see tiny dots of green color things on the glass of my tank. What are they?

I am not able to take a photo as they are very small. I had to really notice to see it.

if its tiny spots and they are pretty hard to scrub off, they could be coralline algae... which is good and bad at the same time.

if its hair algae, its mostly bad...
