jellyfish, yes or no?

i have a 45 gallon tank. i was wondering if i should even consider keeping either a moon jelly or a blue bubble jelly in my tank, i have gotten mixed reviews on care level, ease of setup, etc.

I honestly no nothing about them but check out the LA FISH Guy website he has a bunch of youtube videos and he builds custom tanks for them. He seems to know alot about them. Id start there if I was you

I would not want any jellies in my reef because they could sting my corals fis and anenomies..

Make sure you get a tank that's specially designed for jellyfish. They will not survive in a regular fish tank because they'll get sucked into the filtration intakes.

Not real sure but I beleive they would require their own specific bio-type environment. That's probably why you see the round, rotating tanks advertised which are supposedly designed just for jellyfish. I would think that there would be too much laminar flow present in most reef tank systems to support keeping jellyfish adequately. In other words they'd probably just get blown around all over the place and end up stinging the other inhabitants, as Bill points out, eventually perishing. This is all pure speculation... I have never kept a jellyfish nor do I personally know of anyone who has. I have seen some nice jellyfish displays at commercial aquariums though... All of them were the round style tanks eluded to previously and all had very little current or water flow with no other inhabitants present besides jellyfish.

Jellyfish require a particular water flow pattern to keep them suspended in the middle of the tank away from filtration intakes. The first jellyfish tank style invented was a kreisel, developed by a German oceanographer in the 60s. It resembles a circular window with a flat sheet of laminar water flow around the periphery. Water exits through a wide screen so there are no strong points of suction where the jellyfish could get stuck. Now there are several styles of jellyfish tank that achieve the same purpose. For example, you can use a cylindrical tank with a "mushrooming" water flow pattern that sweeps the jellies up off the bottom. (see: http://jellyfishart.com)
Jellyfish also require a special food because they are used to feeding constantly in the wild.
Once you get the right tank and food, jellies are pretty easy to take care of. They're very tolerant of less-than-perfect water quality conditions and don't require any special lighting.
