Jellyfish breeding in my reef aquarium, a closer look

An isolated view of a jellyfish bell side down in a ramekin on a white background. You can see a side view to the upper right due to the ramekins shape bending the light. The penny is below the ramekin to give a size reference. The largest I have seen these guys get is one cm. I would appreciate anyone who can identify them.

it does seem like a cassiopeia species

Let's see, if they always swimming upside down, probably it's Cassiopeia species. Need strong sunlight for photosynthesis
