Help???? i have no idea what this new thing is

[efoti]

About 3 months ago this orange thing appeared from under my coralline stack and has continued to grow. It is translucent and doesn't retract when touched. I've tried to find out what it is online with no luck. The only help ive gotten was that it possibly is a red alga soft coral. Please help

I think it might be a tunicate. Normally a harmless hitchhiker, but it its growing over your corals i would pick it off.

Im not so sure it would be a tunicate. I am not seeing any similarities but then again i am in no way shape or form educated enough on sea creatures to give my opinion. Its strange that i am having a hard time finding information on this thing. The closest pic to it was of a red alga found off the coast of Australia but did not find any information related to it. I attached another pic that might be a little better.

I also think is some kind of Rhodophyta (Red algae) macro algae.
Maybe Flahaultia tegetiformis
Family: Solieriaceae Order: Gigartinales

With your new picture, i agree, i think its some sort of algae. As long as its not growing too fast, i would think its fine to leave it.

I also think it's algae.
