That is a type of coralline algae.

Also red slime.

Red slime? If This helps, it's pink and it's growing lighter toward the ends. Seems like finger sponge. I don't think it's finger sponge though.

Mr. X is probably right about the coralline, but the dark red stuff on the rocks looks like red slime (a type of bacteria).

I have coralline that is that dark red, and it looks like what's on the picture.

Im Strictly Speaking Of The Pink Stuff. The Darker Red Was There When I Bought The Live Rock.

If you can't scratch it off easily, it's also coralline algae. It comes in many colors.

It's Hard,It Seems Very Much Like It Could Be Coraline Algae. Thanks.
