Moon Jellyfish Polyps

Aurelia coerulea 

 **If you order pre-settled polyps, these may take 1-2 weeks to ship as we often settle fresh plates of polyps depending on how many you order. Loose polyps will ship faster but may still require several buisness days to ship out**

For those interested in growing their own jellyfish! Polyps are the sessile stage of the jellyfish life cycle, acting as little jellyfish factories. When environmental conditions are right, the polyps will start releasing baby jellyfish known as ephyra.  

We offer both pre-settled and loose polyp colonies. Pre-settled means they will be already attached to a piece of acrylic or a plastic petri dish. Loose polyps allow you to settle them on the surface of your choice, that best fits your setup. We sell them as a colony of 10 or 20 to ensure you receive enough to start a healthy colony with genetic variation. 

If you’re interested in raising your own jellyfish, we highly recommend also grabbing a copy of “How to Keep Jellyfish in Aquariums” by Chad Widmer. He covers the entire jellyfish breeding process in plain language. 

The species we are offering here are Aurelia coerulea, the most commonly kept moon jellyfish. These polyps can be kept at room temperature and standard salinity but will need a temperature drop to 60 F in order to trigger strobilation. Polyps should be fed live freshly hatched brine shrimp or rotifers a few times per week.
