Breeding Atlantic Sea Nettles

A few months back I was able to trade a source for some Atlantic Sea Nettle polyps. I've had them for a while, and they have budded off since then. I started with 3 polyps and I have about 12 now. So I decided to run and experiment to see if I could get them to strobilate. I tried adding freshwater to lower the salinity. I waited and that did nothing. A few weeks later I took the polyps and set them in a water bath around 78 degrees, and then added a lot of freshwater. Just two days later and one was strobilating. This caused the rest to start, and I have one ephyra so far. As far as I know of! I'm the first individual who has bred Atlantic Sea Nettles. Aquariums will breed them sometimes, and those are the only other cases I have heard of. 

They are really cool jellyfish, and their ephyra are just as cool. They start out with a little but of frilly tentacles. Moon jellyfish ephyra start out with a stub. So I think these will be easy to feed at an early age. I've heard from aquarists that they aren't the easiest ephyra to raise. The one ephyra I have now seems to be very finicky, which fits that description. We will see how they do I guess. :) I will keep updating as I keep them. I also have Lions Mane Jellyfish polyps and am eagerly waiting for them to produce some ephyra as well.
