What are those kind of kind of critter my tank is around 1.5 year old

Hard to say. Could be either copepods or amphipods! Both are good to have. Hopefully someone else can come in on this.

I know i have a lot of amphipods and copepods but those look like jellyfish of some sort

By behavior, I'm leaning towards some kind of amphipod, but admittedly they don't look like amphipods to me

Maybe @ISpeakForTheSeas will have a moment to take a look and set us all straight
