Jelly Fish

[angelgirl]

Does anyone have any experience with Jelly Fish? Are they hardy? Are they reef safe? Pros and cons? Can you get them? I am curious.
Thanks all

Jelly fish are not hardy and are very hard to keep in captivity.
No they are not reef safe because they will move around the tank and sting everything.
The pros are some of them look cool.
The cons are they will sting everything.
Yes they are available but they are not common and not recommended.

If you can find them I don't suggest it. Even the Newport Aquarium is having a hard time keeping them alive in the displays and they have the best of equipment. Good luck, let us know if you have any luck finding them or keeping them alive.

the reason they aren't reef safe is that they sting everything, and when the get sucked up into a filter the disenigrate and the poisons and stinging cells will get torn into very tiny peices and sting and kill lots of stuff

I totally agree with car guy, True jellyfish are not made for tanks. Although the NJ Aquarium has a round tank with angled powerheads in it to keep them in constant motion but, I dont know how long they stay alive in there. Ill have to ask the one diver I know from the Aquarium. Anyway, Jellies dont really live that long in the wild. 1-2 years max. The only species I know that have been kept in captivity successfully are the upside-down jellyfish whick rest on the bottom and kinda bob around and are photosynthetic. I know they have to be kept in a shallow brightly lit species tank to live tho.

I totally disagree with carguy.
The jelly fish seen in the reef trade are not usually that poisonous. They die because they are cannot be contained in the right kind of system and die of starvation.
I have seen successful jellyfish tanks in Japan but they cannot be duplicated in a home setup.

Well, sorry BurnNSpy, but I gotta say disagree with you. Technially all jellies, anemomes, and coral are posionous. They all have what are called nymatisits cells, that inject poison, like a harpon, immediately on contact. The poison is the same potientcy from each species, but waht changes it is the amount of cells on each tenticle. Did you know that a Portugess Man-O-War is more poisonous than most cobras. Although when you touch coral, anemome, or jelly, you might not feel anything because the human skin is pretty thick when compared to most animals in a reef tank. I'd love to stay and chat, but I got to go. Finally, the Monteray Bay Aquarium has the best jellies.

But needless to say, don't keep them.
