Created a seperate thread. Has anyone here made an attempt to keep them in captivity?

I kept them as a teenager (years and years ago). They were about dime sized and lasted about a week if I recall correctly. Haven't seen any around here for years now.

Are you referring to Comb Jellies?

A google search led me to this site: Freshwater Jellyfish
I'm assuming they are similar in nature to their marine counterparts with respect to fragility. To keep jellys alive for any amount of time, they need specialized aquariums that cost in the $1000's--to keep them from tearing themselves on the sides of the aquarium.

Freshwater jellyfish have an unfortunate tendency to get stuck even on sponge filters, but custom "jellyquariums" don't seem to be essential -- some vouch for regular aquariums rounded off with Styrofoam inserts.

Our marinelab made some ventures into jellyculture recently. We have a kriesel but it was having issues so it is currently empty until it is fixed.
Of more interest to you guys is that some tiny moon jelly medusa were found and are being kept in a quart jar with light aerationwith large bubbles(too big to get caught under the jellies). They are fed almost daily and given frequent water changes. Looks quite simple. When I started volunteering they were holepunch size. Now they are almost dime size.

It is really amazing what the enterprising DIY aquarist can do...I have fashioned a few "ghetto-engineered" tanks for jellies in my time in the aquarium industry...the best temporary fix is actually a flat-sided goldfish bowl...if one can get the aeration just right you have an instant mini-kriesel for under 10 bucks. You can also submerge the bowl in a tank with a screened over outlet for water and an airline tubing sized water inlet. Even if you have more delicate spp. that do not fare well with bubbles (i.e. ctenophores, moons) one can still have a successful tank on the cheap...I used to have a homemade kriesel back in college made from a 10 gal that did fairly well with ctenophores...but a modified goldfish bowl is the simplest solution, works great for jellies, juvenile seahorses and other stuff

How'd you get ahold of ctenophores as a poor college student? We kicked around the idea briefly but according to the coordinator they live too far down to make collecting feasible.

Ctenophores are not confined to deep water, here on the South Eastern cost of NC they can be caught at night with a plankton net easily. I've caught so many of them with one sweep it was difficult to raise the net, filled the collection jar up completely packed with them .
