It's not aiptasia... They are dark red in colour. Tried searching and couldn't find examples of similar. What do you think?
 
Definitely an algae. Probably a red type IMO.

Let it grow out if you're curious....it'll be easier to ID as it grows.

PhycoKey might help. (https://cfb.unh.edu/phycokey/phycokey.htm)

If you're not that curious, this is the best time to remove an algae that you don't want to spread. Reach in and pluck it from the rock.
 
I'm very curious! It is a slooow grower so I can wait 😂 Based on the phycokey website I think it's Dumontia. Very cool!! I will bookmark that site. Thank you!
