Red slime or coraline ?

[dmjr1201]

Just curious, is this red slime or coraline algae? I know the purple is coraline. My concern is the red in there. Heres a few pics of the same rock.

I do not want to start panicking, any info will be appreciated.
Thanks in advance

Looks to be coralline. Is it hard or slimy? Slimy is cyano, hard is coraline

I had this same algae in my 26g. It is not hard like Coralline, but slippery and soft to the touch. Using a butter knife it can be scraped off. At times I was able to peal off 1-2" squares. You can see it to the right of my clam.
After much research, I believed it to be some type of Turf Algae. It did spread a lot.

I think it is a form of cyano. I used to get those all of the time in my FO tank.

Hard to tell from the pick but looks like a coraline to me.
