Just was wondering what the deal is on these guys....i see them at this not-so-lfs in the medusa and polyp stages and have been interested in them. I did a search on here and only came up with a few hits on their needs. I saw that they require tall tanks and live foods ...i understand the live food but in what quantities, what do they eat specificly, why do they need tall tanks ....are they escape artists like octopi? if anyone has intimate knowledge of these guys i'd be interested in picking your brains on these guys. another thing i was wondering was what kind of set up would you need? lr? ls? thanks for the help.

I don't know anything about housing them. I can see how someone would though since they look so cool. All I know is that from the setups I have seen at aquariums, the tanks are tall, and I guess depending on what type of Jellyfish you have, complex lighting doesn't seem to be important.

There isn't any live rock. And I am not sure how filtration can be run since they look like they can be easily sucked into a powerhead or skimmer.

From what I would assume... I would think that Jellyfish are pretty hardy since the Jellyfish I see at my beach are in some pretty nasty water compared to the water quality in Ventura or Orange County. I know they can eat plankton or brine or whatever comes up in a red-tide

i went out and did a little research on them and found some are photosynthetic and others need to be fed live foods. i have yet to figure out why they need deep tanks its perplexing to me. but what i was thinking was you could have a sand substrate (no CC cuz they could poke their bell) use like a seagrass like "turtle grass" never heard of it but some one recommended it as a ground covering. and then have a powerhead on one end w/ a filter over it and have it set to a very low setting since they pretty much get pushed around by current, and then put a tank divider so that the jelly cant get near the ph intake. also on this side one could squeeze in some live rock to help filter the tank and is still out of harms way. my lfs has 3 different kinds the upside down jellys, the "blue jellyfish" and then there are "brown jellyfish" all are generic names but i assume someone has a fairly good idea what im talking about. the upside down jelly's im not all that impressed by the only thing appealing about them is their price, $6.99, while the blue and brown ones are $19.99. anyone care to clear up the species i may be speaking of? and anyone care to comment on my idea for the setup. thanks for the reply Blue

Jon,
Jellyfish would be an interesting specimen to keep . Where did you hear or read that they required overly deep tanks? I would think that is where you could get your "why" question answered. Good luck with them , and its nice to see someone finding out the where , why , and how BEFORE buying something.

someone said it on here.....and on reefcentral. im thinking it would be more difficult to keep them alive if they require light for photosyn. because you have to assume they will be high enough in the tank to get the amount of light needed. i'll report back when i find out in case a few months down the line some one else is interested. as far as the research first.......my theory is if you buy them and then do the research youll find yourself saying i HAD jellyfish, where as if you research then buy, you can say i have jellyfish. Thanks for the reply tbt

Anything that I have ever come across says that jellyfish require a rotationg aquarium for survival. They are heavily dependent on a constantly alternating current. You could use a tank like the aquatic revolution... if you are rich. I read an article in FAMA about them a couple of years back. Of course, that imformation is somewhat sketchy at this point. Maybe you could order a back issue of it (not sure wich month of what year though). Good luck.
