neon orange on rocks

[oryansreef]

can't get a pic of it. it seems hard? not sure how to explain it

Not that this helps ID it, but I had the same thing a while back, and it just disappeared. It only fluoresced under the blue LEDs and was a red'ish orange color as you have described. It was only on one rock, so I just assumed it might be some remnant of a coral that was previously on the rock. I don't recall if I took any pics of it, but I'll look.

The best I can do under blue. Tried to get it in the center of the picture

Impossible to see from the pictures, but it could be encrusting sponge, or encrusting coraline algae - it does occur in orange sometimes.

oh, did not know coraline came in a orange. it could be that has a smooth texture not rough like purple coraline.

Coraline comes in a few different colours. Green, purple - light or dark, occasionally orange. I've seen it have different textures too - smooth, almost bubbly looking, plating and even pointy and sharp.

Nature is amazing.
