Is this coraline? I think so.

Was really looking at the tank today. Spotted two hermits that had a lot of pink on their shells. Then I noticed this frag plug. Looks like coraline to me but a thumbs up or down would be nice.
First pic under white light. Second under 12k blue and white.

Yup. I’m finally getting coralline algae in my tank. I was so proud when I saw the spots on the glass lol.
