Matt_95 Posted April 22, 2014 Share Posted April 22, 2014 I've had this tank sitting on my desk cycled for a while with a damsel in it. I wasn't sure what to do with it until I found a few (thousand) jellies in a lagoon I was snorkeling in. I believe they are Cassiopea xamachana. So this has now become a lagoon that will only really house organisms from my local area. The jelly lagoon didn't have any coral in it that I could find, or any rock. However I have kept the live rock and added some corals that were cluttering up my pico. Hopefully they will be fine with the very very low flow the jellies need. The filter is a cheap Chinese one, it's the only one I had that wouldn't have to much flow. I plan to get a better looking HOB when I can get to the shops to de-clutter the tank. Substrate is silica sand, like what the jellies were found on. Once the substrate has gaged for a few months I will be adding some Halophila ovalis which they were found with and when I find some nice looking macros I will add them. There were lots of anemones I found with them, a lot if them were aptasia looking ones that I don't think I will add. Some swimming anemones and lots of carpet anemones. There were also a lot of urchins. I stressed the jellies when I added them to the tank which unfortunately killed my damsel. I would like to have a fish in here. There were lots of blue eyed cardinals with the jellies, the tank wouldn't be big enough for one though would it? Link to comment
Eclipse Posted April 22, 2014 Share Posted April 22, 2014 You mean... Jellyfish? I'm sorry if that's what you meant but it's weird because you're talking so casually about it, but jellyfish need specialized tanks I believe? Link to comment
Matt_95 Posted April 22, 2014 Author Share Posted April 22, 2014 Sure do, these guys don't need a very specialized tank though. They just need very low flow. They sit on the bottom with their tentacles exposed. They're photosynthetic and they will also eat plankton. Link to comment

antsypants Posted April 22, 2014 Share Posted April 22, 2014 that's crazy! how long do they live? Link to comment
Matt_95 Posted April 22, 2014 Author Share Posted April 22, 2014 These are upside down jellies Cassiopeia ? Nice, love the zoas! That's them! Cassiopea xamachana I believe. Thanks, these are the Zoas I don't want in my reef, when my nicer Zoas grow out a bit I'll add them to this tank as well. We don't have a good selection of Zoas in Australia like you guys do overseas. that's crazy! how long do they live? I'm not sure on that one actually. These guys aren't as large as they can potentially get. I plan to divide them to keep them small and I am hoping to breed them. I'll be adding them to the refugium of my larger tank when it's set up as well so they can grow large. Link to comment

I remember this A-Z undersea book I had when I was little and upside down jellies were the U pretty amazing what we can keep in a glass box nowadays, huh? keep us updated, this is practically my undeclared childhood dream!

I've wanted to keep these for a very long time as well, they had them in an exhibit at Underwater World, I never thought I would ever get them though. From my research, the larva prefer to settle on the underside of fallen mangrove leaves, I'll have to get a few soon. Edit: just went for a walk and got a clean up crew and some fallen mangrove leaves for the tank. Link to comment
Matt_95 Posted April 26, 2014 Author Share Posted April 26, 2014 I'm not sure if I'll keep this tank how it is or not. I'm getting huge amounts of cyano since I have cut back to the flow and I don't want to be battling that the entire time. Also I can't have any other live stock besides the corals because they release nematocysts into the water and kill the clean up crew and any other stock I have in here. Not sure what to do.

pismo_reefer Posted April 26, 2014 Share Posted April 26, 2014 Holy sh*t.... You have live rock, with jelly fish, in a rectangular pico tank? Theres so much wrong here, and not enough of you see it. Thats reeeeelly concerning to me. Link to comment
Matt_95 Posted April 26, 2014 Author Share Posted April 26, 2014 These aren't your regular jellyfish, they don't need a kriesel like most jellyfish, they just require low flow and high lighting. They don't use the water column and instead spend their lives upside down against the sand bed. Link to comment
afyounie Posted April 26, 2014 Share Posted April 26, 2014 Very cool. I looked up these on Google and found some pretty nice color morphs. Also saw a picture of a crab wearing one of these on its back. I did notice that a lot of these jellyfish live in areas with sea grass. Do you plan on planting some sea grass? Link to comment
Matt_95 Posted April 26, 2014 Author Share Posted April 26, 2014 I've seen blue and purple ones online however all the jellyfish I saw in the wild were green. Once the substrate has built up enough detritus I will be adding H. ovalis, probably the only sea grass I can get that won't make the tank look odd. Link to comment
Matt_95 Posted April 28, 2014 Author Share Posted April 28, 2014 I'm really thinking I'll start this tank over as a rock pool with local corals or something. The tank is becoming an eyesore, the low flow causing huge blooms of cyano and diatoms. Not sure what to do with the jellies, maybe move them to a larger tank tank that I can run more flow through. I was planning to add some to the refugium of my larger tank but I don't want to risk them nuking my livestock. Link to comment
Matt_95 Posted May 11, 2014 Author Share Posted May 11, 2014 I've swapped the substrate out of this tank and done a rescape. The new substrate is oolite grade aragonite with a small amount of mud right at the bottom so I can add some sea grass too the tank. The jellies are doing very well, 4 of them swam I to the intake of the filter a week or so ago and they are healing very fast. I've added a few new corals. Unfortunately my echinata has killed my maroon acan lord, not very happy about that . I've added a small damsel to the tank just to see how successful it can be to keep fish with these guys if they don't stress. I've also added a golden ring cowrie. Link to comment
Cameron6796 Posted May 12, 2014 Share Posted May 12, 2014 Very cool experiments so to speak I'll be following Link to comment
Matt_95 Posted June 12, 2014 Author Share Posted June 12, 2014 I'm really thinking I might give the jellyfish away, I'm getting a bit bored of them and I would love to do something else with this tank. Link to comment
