i think you need to have a constant (soft) current and a circular tank.

that they built a special tank that is completely round w/ current so it would never touch the sides or it would die. pretty neat.:eek:
 
it's really not that hard. a round tank is ideal, but you could also get a normal rectangle tank and use an insert to get round walls. then you drill holes in the top of the insert for overflow, drill the outer tank, make a sump, and you've got constant current for these guys.
i've taken care of saltwater jellyfish in a rather small display at the waikiki aquarium. the round aquarium was maybe 4 feet in diameter, 5 feet high.
 
they are not really jellyfish. They are closely related to the hydra. They do look like jellyfish though.

I've heard that lake erie is flooded with them. there are also lots of little ponds in new york that has them
 
They're not true jellies in that they're in a different class, but they are jellies in respect to being the medusa (free-swimming) form of cnidarians. It's kind of like referring to flies and beetles and ants as bugs, but knowing that the only "true" bugs are in the order hemiptera.
They show up every few years in a few lakes in St Paul, but most people haven't seen them-or maybe they just think they're seeing things. It would be awesome to see someone keep them successfully!
 
I live in Michigan and I've never even heard of these. It would be sweet to see some pics.
