does anyone have a jelly fish tank? i was at my lfs this afternoon, and saw them for the first time in captivity like that. i believe they were called...upside down jellies or something. don't know if that will help. i was wondering what is the smallest tank i could hold a couple in. i would like to do a 20h because it will fit on this wall i have perfectly. i think i will be able to do it really cheap, because i can make most the live rock in the sump of my reef over the next month or so, and throw a few show pieces from my reef in the new jelly tank to grow some nice colors. well thanks for your time.

hclh2ofish talks about a 10g upside down jelly tank.
Hopefully he will answer your questions here.
From what I understand jellies require some special care. Like good water quality but low flow.

Upside down jellies (Casseiopeia spp.) are not really found in reef type environments. Live rock will just provide a surface for them to tear on. If you'd like to set up a dedicated tank for them, it's fairly simple. All they need is low flow, high light, and a sandbed. I take care of a 20 g tank full of them in which they've spawned and the larvae have settled.
The way this tank is filtered is a reverse flow type undergravel filter. The pump has a sponge on it so that the jellies won't get sucked up by it. The sandbed is a sugar fine aragonite. The lighting is a 6500K Metal halide. Water quality is not all that big an issue--they come from pretty high nutrient areas.
Here's another thread with a bit more info from galleon about raising the larvae. I never tried it but it seems fairly simple:

I'll second Matt's response. There are hundreds of these things on the sand/mud flats near the mangrove keys by my house. Lots of birds roost in the mangroves and the water is downright filthy. The upside down jellies just rest on the sandy bottom in a few feet of water. Their requirements are a bit different from most other jellies.
Yah, I've got a 10gal with jellies in it. Was more accident than anything as they all came in off some LR.
I don't have any LR currently in the tank (gonna be moving a small chunk in there just because it still has hydroids on it and keeps popping up juvenile jellies)
Once we move, we'll likely go with the undergravel method.
I currently have crushed aragonite in the first 1/4 of the tank...for keeping my pods happy, the rest is sugar fine.
I *don't* yet have my MH..looking at a pendant once we move. They're doing ok under HO but definitely not as good as they could.
For flow in the tank, I have a RedSea Nanofilter...I stuck filter material around the inflow tube to keep em from getting sucked in.
Water params are great....all zeroes, but I've found they seem to do better when there are more levels of nitrates....I'm thinking it could be the zooxanthallae utilizing it as 'fertilizer' but that's just a guess.
I feed a small piece of squid once a week for the pods to munch on and a drop of clam food every week.
I've seen some of them grab pods and eat those, but very rare.
If you *do* get some to raise, definitely get the better lights....and you don't need *any* LR in the tank if you don't want. With no other critters in the tank, the bioload is nothing.
Only issue I've had to deal with is cyano bloom since there's very low flow.
Good luck w/your jellies! They're a fascinating creature...no brain...no nervous system...sorta like some of my ex girlfriends!
