Algae identification

[needmorecowbell]

I just added a clown to my cycled tank and found little purple spots on the tips of some of my base rock. It's not like my corralline algae but I might be the start of it. I just want to know if there's any other type of algae like this. My nitrates are a little above 0 and I have a strong cuc. ( there's a lot of em lol) thanks in advance

I checked back on it today and there is more. It's kind of pretty but I don't want it if it's telling me that their is something wrong.

sounds like coraline to me,if its hard to touch and hard to scrape off

Theres too little to scrape off, or touch. Its more like its colored into the rock. If I had to guess though, it would be coralline. I just don't know the beginning stages.

point a powerhead directly on it,if it detaches its not coraline,
