ID Stuff on Live Rock

[mdisalvo55]

It's a cluster of maroon bubbles growing on one of my live rocks...I touched one and slimy stuff came out...is this something I should be worried about? I thought it was bubble algae but it isn't green its a maroon color. Let me know!

I have red bubble algae growing in front of a powerhead in a tank I'm storing live rock. The bubbles are softer than green bubble algae; but, the bubble get about the same size.

I would say in general, all bubble algae is bad for a reef tank.

Best of luck,
