Is this normal?

My rocks are turning bright green! This never happened in my other tank so I'm not sure if this is good or bad. Its not fuzzy and it doesn't look like the beginning signs of hair algae. Its just a bright green color and its on all the top rocks. Should I be concerned? All my parameters are where they are supposed to be. My light goes on from 2pm-10pm and its a small 10 gallon tank.

hard to tell without pics, but most likely coralline algae. Very good to have.

Probably Coralline and it will probably turn a different color down the road.

If it's hard to the touch it's green coralline.
