Is there ANY point in keeping Jellyfish?

[Biogeek]

Although it is certainly not easy, it is possible to keep jellyfish (and the upside-down jelly, Cassiopeais one of the easiest) in an aquarium if you have the proper tank design and know what you are doing. I'm not defending Big Al's, because I somewhat doubt that they have the correct setup (I haven't seen it), but just wanted to let you know that it is possible, and point you to some resources for keeping jellies at home if you're interested. I have a detailed article on jellyfish and ctenophores in the Aquarium.Net archives, and discuss jellyfish biology and how to keep them in the aquarium here. There are a variety of other jellyfish resources listed on the About.Com guide, so you can always cruise through there if you're interested as well...
