Does anybody recognize this thing? Its like a little medusa lol, it makes the same type of movement but its so tinny, ive seen them before but never knew what they were

Do a search for Cassiopea jellyfish and see if you think it's a match.

I dont think thats it, the one you mentioned is kinda larger than the one in the tank, its really really small but it swims around the tank just like a jelly

Okey. We breed Cassiopea at work and they start to look like a jellyfish when they have a diameter of about 4mm. I don't know the size of your one
Anyway, the polyp stage for many jellyfish are hardy and could sit for a long time on a rock before they stobilate and release tiny jellyfish.
