Fluorescent pinkish/orange speck on live rock

[Easy Reefing]

Not sure what they are . Are they cyano ? If so , how should I get rid of them .

 

[Ron Reefman]

I seriously doubt the fluorescent orange stuff is any form of cyano or algae. But that said, I don't know what it is either.

I occasionally get a bright, fluorescent pink spot (leaning toward orange). But it doesn't get big and it goes away if I take the rock out of the water and dry it out. I suspect it's alive. Maybe a type of coraline algae, but that's purely a guess.

Let's gett some other opinions. #reef squad

Do they glow pink under actinics? Could be phosphate bound to rock.

Yea , they glow pretty bright . I’ll check it out again today . And thanks , I’ll look into that

If it is phosphate bound to rock , is it bad ?

Id take a guess at coraline. I ordered KPAquatics live rock that had a few colors of coraline. I was shocked to see how bright and colorful the rock was under my lights. It practically glowed. Unfortunately that color didn’t stay- its now a normal coraline color now. Too bad, it was beautiful.

I didn’t know coraline came in different colors ! It does look pink under whites but glow really bright under blues . Thanks for the help

I have few dots to and got worried but it didnt spread or cause a major issues so i just keep doing test and checking how things are going.
Mine dots are orange but i have red alage growth and purple so idk why this orange one glows at night

it is dead/dying Coralline algae.
As was shown in this post

Coralline likely died off on this rock after being exposed to air or other shipping related reasons. It quickly either turns white or replaced with other algaes/more Coralline.

I find that is when an Asterina Starfish has munched on my coraline it leaves the little bright florescent patches

I think it’s likely the coraline algae dying off, thanks for the replies everyone
