Upside Down Jellyfish   11/15/11
Hey Crew!
So recently, I visited the Shedd Aquarium here in Chicago and saw their amazing Jellies exhibit! Immediately, I decided I wanted to try keeping jellyfish.
After extensive research, I determined that the Upside Down Jellyfish would be the most suitable jellyfish for captive keeping. The tank that they would be going into would be a JBJ 28 Gallon Nano Cube CF Quad. It has four compact fluorescent bulbs for a total of 105 watts of lighting. Would this be enough lighting?
There will be some macroalgae in the tank as well as in the back of the tank to help with the biological filtration since there will be no live rock. Currently, the tank has about 2 inches of crushed coral as a base, but to get the jellies closer to the lights and to help with filtration, I am looking to add a lot of live sand (fine sand not crushed coral) to increase the sand bed to around 5 inches.
I am looking to keep at the most three small upside down jellyfish. I just want to confirm this, but will phytoplankton, zooplankton, and newly hatched brine shrimp be good food-wise? Any other recommendations would be appreciated! Thanks!
<I can't encourage you enough to seek out the latest issue (29) of UltraMarine Magazine (UK)... There's a very nice, complete, up-to-date piece on this genus and its captive husbandry; I believe penned by David Wolfendam. Cheers, Bob Fenner>
