What is this thing fluttering around in my tank?

I just spotted this thing. When I first saw it, I assumed it was a part of one of the anemones I've been chasing around the tank for the past month, but it's clearly not. Ball Anemone maybe?
Here's a video of it after I managed to catch it.

It's a homing beacon. It's calling in the reinforcements.

Looks like Medusa stage of a hydroid. Harmless but don’t live long in tanks

Baby jellyfish in my tank??

I woke up to see what seems to be baby jellyfish swimming around. Any idea what it could be?
