Any idea what this may be? At first I thought it was just a string of algae. But watching it and paying attention closely it seems to shorten or lengthen itself.

Digitate Hydroid. I have a couple as well. No ill effects so far, but I still try to pick em out

Get rid of the ones you have now to stop possible spreading. I started with one and now have countless and they don’t play nice with coral...
