What is this pink stuff showing up

[jillw28]

Hi!

I have these pink spots showing up in several places in my tank. It is the pink spots that are on the seashell at the bottom of the tank. It has shown up on my coral branch and also on one of my crab shells.

Anyone have any ideas what it may be?

Thanks!

Looks like coraline algae. Good stuff and very pretty. Eventually will cover all your rocks like mine in the photo

It's a good sign of a healthy tank too.
