Was wondering if this was indeed coralline or something else, its bright neon orange with a smooth surface and Fluoresces greatly when just my blue LED's are on. It's only on the rocks, never on the glass or equipment in tank.

It grows very slow (rock pictured is 9 month old (was dry rock), its not a sponge as I touched it and it felt hard like coralline
Pic was taken with my phone, has a tough time color balancing but you can see the orange spot in the center of the image

I have mostly red coralline growing with purple filling in at a slower rate and the orange stuff is even slower.

It could be an orange coralline, but IME, it's usually a sign that it's a damaged spot. You can see this phenomenon if you soak a coralline covered powerhead in hot water then put it back in the tank. The coralline is usually bright orange like that.
