ID help

There is something new on my tank glass it is white/clear and stuck to the glass it looks like it has 2 peices of thread that extends out and then retracts back in they are about 4 inches long. I tried to get a pic but it didn't turn out it looks like there are more. any ideas? Is this something I should get rid of? I don't want any more headaches I just got rir of red slime algae. Now batteling hair algae
