Mystery Orange Growth

[Oceanlotion01]

I have a mysterious orange growth that looks like spaghetti noodles growing on my Chateo.. I removed it once a few weeks ago and now it has appeared again, I am struggling to find any information on this. TIA to anyone who can identify!

THANK YOU we just recently got a sea hare for our green hair algae problem and he’s doing very well! Appreciate your help :)
