Cassiopeia xamachana - Upside Down Jellyfish

After modifing this 3 gallon tank to generate a circular flow (kreisel), I raised a culture of brine shrimp in it to see how well the design worked. I was very pleased with the result. later that week, while getting dry goods from the local fish shop, I saw a bowl shaped tank with Upside Down Jellyfish polyps and ephyras. These had come in to the shop as hitch hikers. These ephyra ended up killing the sea horses housed in the bowl. I asked the owner if she would part with a few. As I hoped to raise them through their life cycle.

Adult jellies (medusae) reproduce sexually resulting in larva (or planula). After a period of drifting, the planula will settle on any and evey available surface becoming a stationary polyp that can clone itself. Each polyp, resembling aptasia anemonies, will begin to bud-off a small, free swimming medsua called a ephyra.

Four little ephyras came home with me that night. Six more were to follow the next day. It's been three weeks now and all ten are with me and growing fast. The largest is now 7/8" across the bell.

do you still have the Cassiopeia? Did they produce polyps and replenish there numbers?

I kept the Cassiopeia for a little over a year. They did reproduce a lot (I dare you to stop them). But I decided to devote my energy to the local cold water jellies that are more available. Cassiopeia are a warm water jelly and  have special lighting requirements like corals.

thats sweet! how did u make it? what filters and lighting? and what tank?

[jaysunwatts]

Thanks, I used a 3 gal tank, baffles cut from plexiglass, and aquarium grade silicon purchased from a pet store. A drill press with a hole saw was used to make a large opening for the main intake. A small hole, the size of ridged air line tubing, was added for the return. A 500 micron mesh screen is then siliconed into place to make the diffused opening. Next, I added baffles to three of the four sides, using silicon. Via Aqua VA-360 600l/h pump. Coralife, 9w 10,000k light
