    Here is a photo of my Upside Down Jelly fish (Cassiopeia sp.)

    [​IMG]

    This jellyfish uses light to photosynthesise and is thus fed by algae inside the body. It also has the ability to capture prey by excreting a mucus / slime in which plankton is trapped and consumed.

    They do not swim around much, and will just lie in one place and pulsate every few seconds. It does not really sting humans like others, and I have touched it a few times with no sting... :whistling:

    If anyone has any other information on them please feel free to post.

    Thanks

    Does someone have any explanation for that slimmy part above the jelly fish is for? It stays above until the flow comes back again. I have not seen it eaten that part with the particles in.

    I will take a video an post yes... I am just sitting with a power failure at the moment. Will take video tomorrow evening maybe.

    Aparantly (and note on the word aparantly) they also change their bodies to blend in with the surroundings. If they are in rocky areas they would turn more brown. If they are in green algae areas, they would grow out greenish parts.

    Have a look in the middle, they have a leafy type of area, and aparantly this may change in it's environment.

    It's really a strange creature, where did you buy/get it? And if you don't mind me asking for how much?

    Okey, our power just went on!!! WOOOHOOOO!!!

    So, here is another photo of the body, you can see it getting greenish "leaves" on it, mimicking the green algae in the back I recon. Freek's one does not have the green in the tank, thus less green I imagine.

    Here it is agains the glass, so you can clearly see the bottom side of it, just like normal jellies...

    And here is the pulsating:




    Got them from Exotic Pets in Boksburg. They are quite cheap - R120 or R150 I think.
    They do however require a specific tank though, as they must have very little current and alot of light. They are naturally a lagoon animal mostly... His tank mates at the moment are small box fish.


    Nothing beats the night anemone - except my NPS of course... LOL!!!!

    I would hazard a guess , like all other jellies quite short (probably up to a year) . Although with no predators , currents etc, this could probably be longer

    Curious little animal or organism? :p Very interesting Jaco, I expect an article from you in a couple of months time about their care and feeding. ;)

    Does it move around a lot? Would powerheads be an issue, as they are for anemone's?

    I saw some masssive buggers in Mauritius. Some of them were about 35-40cm across and beautiful

    Viper, during daytime they do not move around. However, every morning it would be in a different place in the tank. I would recon it is instinctive as in nature the plankton migrates into open water, so the jelly will swim around capturing it. I just have not had the time or "lus" to sit through the night and watch it, so how long it swims around for I do not know.

    Powerheads will be a big no no in two ways. The obvious is being diced up but also these guys require very very little flow. My water moves only a bit, and when I feed the box fish brine nauplii, the brine swims with ease, and is not pushed around by current.

    I have also learnt from further research that in some instances people report the lifespan for a few months, and others report them to live years. I think it all depends on the age of the specimen you bought initially.

    Mine is looking very nice, and doing incredibly well under the LED unit. Colour is turning nice and dark, and the "leafy" areas of it is also turning darker in some areas.

    I will do a report in a few months time with regards to keeping them, but up to now it is fairly easy.

    Judging by the size I saw in Mauritius, I reckon that they can live for quiet a while in the wild. I'm not sure how long they live in captivity
