It is possible that these are coralline. Get a turkey baster and try a see if you can blast them off. If you can’t blast them off, then its coralline.

Looks like coralline. Most likely is. The purple on the trumpet frag definitely is.

I did a water change today and used a toothbrush to scrape off the rocks and yea it’s not coming off almost like it’s apart of the rock
