Neon Orange Coralline Algae?

[CommanderInReef]

I've had this tank running for about 2 months now. there has been this orange bacteria growing on my rock and it's got little spots on the sides but the main spot is the top rock. is this coralline? it looks awesome and reflects in the light but the iphone can't get it without the reef glasses over them. Would love some more info on this. I accidentally had the salinity at 1.035 from a refractometer that i had wrongly used distilled water to calibrate. maybe the higher salinity caused this?

Coralline comes in every color - even black and white. That could be bleached/stressed purple, or orange... or it could be sponge. Most oranges live on the underside or rocks and out of the direct light. They used to be really common in Pacific live rock. Orange never seemed to like water parameters that strayed too much from natural seawater and was not as forgiving as purple.

Like above mention, coralline fluoresce when stressed. I found that asterina starfish eat it because there would be a neon trail going to the starfish.

Scrape some off give it a crazy name and sell it. “Technicolor Yawn Corraline $250.00”

I had a purple coralline die and turn that color orange.

That appears to be a sponge, not coralline.

The texture looks like a sponge. Like @JGT and @jda mentioned before me.

It could be some strange rare fungi from Indonesia.
