I Noticed these Neon Orange Dots on my LR today does anyone know what they are and if they are bad or not

Sponge maybe? That's the first thing that comes to mind if it's orange.
 
I get a few spots of that occasionally but they only last a few days. My uneducated guess is some kind of coralline algae growth phase.
 
If they're bright fluorescent orange, it may be coralline that's been damaged. I see it sometimes if an asterina snacks on a patch of coralline, or if I soak a powerhead in hot water and vinegar for a couple of hours.
