My juvenile cold water Moon Jellies have been growing steadily over the past few weeks. Recently they have become large enough that they have stopped growing. I imagine I have about 50 currently. They are all inside my breeding system at the moment, though. They likely need a larger tank to grow out in. So I filled up the 20 gallon pseudokreisel tank. That should be plenty of room for the jellies until they can be sold.
In other news, I am waiting on a shipment of 5 Upside Down Jellyfish from Florida. I am going to try and use a method of in vitro fertilization to produce polyps. I will have more on that later. If it does work, I should be able to obtain polyps from more complex species.
