I just got a jellyfish. Does anyone know what they eat. Has anyone had any experience with them? Any help would be greatly appreciated.

Didn't your fish store guy tell you? Or didn't he know. You shouldn't buy something that you know nothing about.At least WHAT IT EATS. Sorry if I sound harsh,but Impulse buying should be kept to a minimum in this hobby.I wish I could help but I know nothing about jellyfish. Good luck.STEVE

Those aren't harsh words Mr. Salty. It's true that I should do homework on things I buy. But really what are the odds that I would think my little fish store would get in JellyFish in stock. Impulse buys are the worst the that happpens in hobbies such as ours but sometimes you just cant help yourself. I have however done some homework on my new treat. They're filter feeders I've learned. These JellyFish were only ten bucks and people were literally in line to buy one so of course I had to have one. And I'm sorry to hear they have such short lifespans.

I was told that this variety of jellyfish would not sting. And that was true. I already had to save him from those freakin purple tip anenomes. I don't think I will be able to touch the jellyfish for long because I read that sometimes jellyfish have to grow a little to be able to sting.

All jellies are carnivores and eat fish or other marine creatures- often plankton. They do not actively seek prey or hunt, but rather passively catch prey as it drifts by. Using the nematocysts on their tentacles, they are able to stun or kill food. The food is then brought to the mouth and digestive cavity.

By the way Jellyfish don't make good pets. they are very hard to keep.
They require some specially modified aquariums called Kreisel, that are usually very expensive and complicated. Although not all species require such an elaborate aquarium, the species with long tentacles do.
To minimize damage the water flow in these aquariums not only has to keep the Jellyfish in constant suspension, but also be discharged in a very broad and evenly distributed manner. Water leaving this aquarium must be done in a way that doesn't allow the Jellyfish to be drawn into these overflow.
Filtration is similar to a Reef System and water must be free of nutrients and ticulate matter. they are invertebrates they will not tolerate any forms of toxic metals, like copper. Water temperature of most Jellyfish ranges between 58 and 62 degree's, thus requiring a refrigeration system or chiller. each species is different, so this range may vary.
they require a huge amount of live food. In nature, they eat plankton and algaes. In captivity this food must be cultured, and these they need to be fed a variety of algaes greenwater, and brine-shrimp. but, hey! I may br wrong

We had a jellyfish tank at the London Aquarium. Its a huge circular tank that the water flowed around - looked like a huge wheel. The jellyfish flowed round and round, with actinic lighting behind them - it looks fantastic.
