Moon jellies have a white saucer-shaped body that looks like a pulsing full moon. Their stomach has a distinct four-leaf clover shape in the center. Because of their translucent bodies, moon jellies will glow with whatever color of light is shown upon them.
I’m totally going to buy some of these suckers when my current 10 gallon’s fish give out. They’re going on 2 years here though!

You can buy these?
yes, but you apparently need to have a tank that doesn’t have high water flow or anything sharp that they can catch on. So no pumps or filters that push water into the tank, only undergravel filters and the like.
