Don’t they sting?

He doesn't have it anymore :-(

that's how they catch and eat prey.

Depends on the species of Jellyfish. Some sting some don't. There are some species of jellyfish that require high lighting such as MH's as they are photosynthetic like corals.

Jellyfish require specialized aquariums. Oval or circle shaped aquariums and needs a specialized type of flow pattern, too strong flow and it will smash them against the glass which will lead to death. Not too many people/stores carry jellyfish. I was one out of a hand full of people that keep jellyfish in California. Specialized aquariums are EXTREMELY expensive, like $5,000+ for a 50 gallon tank unless if you build one yourself. The easiest out of all the jellyfish are the Moon Jellyfish. But they require a VERY VERY large specialized aquarium as they get 12-14 inches in diameter and they need a chilled aquarium, in the 55F-60F range. I'd say the second easiest jellyfish to keep is the Upside down Jellyfish. They are photosynthetic like corals so they will need MH lighting. They don't really require specialized aquariums. A regular square aquarium with very, very well covered intake pipes will work. They need very low flow and a very soft fine sand bed with no rock, corals, or plants or anything. Just a tank with a clear sand bed. They are called the Upside down jellyfish because they will swim down and stay on the sand bed upside down collecting light, they don't mover around a hole lot like other jellyfish, so they aren't as popular.

Here are a few pictures of the Upside down jellyfish. Upside down don't require a chiller as they come from tropical waters such as Florida.

Here are a few pictures of the Moon Jellyfish. These guys require chilled water as they come from the Californian cost.

If you are very serious about getting into jellyfish. I'd suggest you do LOTS LOTS of reading before you start, here are a few links to get you started. I HIGHLY suggest you get the book called: How to Keep Jellyfish in Aquariums: An Introductory Guide for Maintaining Healthy Jellies By Chad L. Widmer

You can get it from Amazon for $21.

I do have access to several species of jellyfish such as: Moon Jellyfish, Comb Jelly fish, Gooseberry Jellyfish, Sea Nettle Jellyfish, Crystal Jellyfish, Cross Jellyfish, Chrysaora fuscescens, Lion's Mane Jellyfish, Purple-striped Jellyfish, Egg-yolk Jellyfish, Sea Walnut Jellyfish, you name it. I would keep Jellyfish again if my parents let me have a chiller, and another large tank. LOL I do have most of the materials and the know how to make a specialized Jellyfish aquarium.

Jellyfish keeping is the new frontier in the aquarium hobby.

The Blue Jellyfish (Catostylus mosaicus) is another easy jellyfish species to keep. They are tropical so do not require an expensive water chiller. You can keep them in a regular fish tank as long as you put a mesh guard around any filter intakes: you have to protect the jellies from any strong points of suction so they don't get sucked in and liquefied.

There are some videos and instructions for keeping them in an aquarium at http://www.jellyfishart.com

One last thing... I saw you fed a guppy to your polyorchis jellyfish. I tried the same thing and, after many tries, finally got it on film. Barely. http://www.youtube.com/watch?v=HheMqLyw1d8

It did the same thing with me: spat it out after a few hours. But only after digesting the eyes of course.

WRONG! Catostylus mosaicus are extremely hard to care for. They do not last long at all.

How long did you try Catostylus for? Some batches are better than others. If you start off with healthy specimens they do pretty well. The public aquariums keep them alive for an average of 12 months.

Rent The Movie 7 Pounds Just For The Jelly Fish Scenes!

I have a jellyfish tank. It's been wor. I didnt recieve the seeded gravel when they arrived  and I ended up with toxic water. It about a month of constant monitering before the tank ws good. The jellies are amazing though. I have a LED light in the tank so they look sooooo cool. Also, the setup is rather pricey.

I always wondered if you could somehow have a jelly fishtank...

 

I went to the Chattanooga Aquarium a while back & fell in complete LOVE with their jelly exhibit!  ...ESPECIALLY the Upside Down Jellies, like the ones posted above.  So beautiful...
