Upside down jelly fish

[4nReefer]

Hi guys, have anyone had any success with the upside down jelly fish in a reef aquarium. Online says they not reef safe but my LFS has one in his mixed reef. He says they totally harmless. If I get one what should I look out for or should I just let it go and not mess with it...lemme know watchu think. Right now I have a:
1 diamond gobby
1 leopard wrasse
1 marine betta
1 snowflake eel
1 fire fish.
1 chromis
1 Anthias
Shrimps, snails, starfishes,crabs.

Corals:
Lord Acans
Leather coral
Hammer coral
Zoes
Gorgonians
Clams
Lobo coral
Brain coral
Green polyps.

A word of caution, that marine betta will eat every fish on your list when it grows up with the exception of the eel.


As for your OP, I unfortunately have never heard of upside down jellyfish.

Imo they wont go after fish unless you feed the feeder fish. I have a full grown 8 inch marine betta with all those fish on the list except the eel and diamond goby. It has never gone after smaller fish, even though it has been with smaller fish that would fit his\her mouth for years. In nature they mainly eat crustaceans, so they dont instinctively go after fish (unless starved I assume). Their hunting behavior is actually not very useful for hunting fish.

If you feed them feeder fish tough, you are basically training that behavior. The only type of aggression I see from mine is towards negrosensis leopard wrasse, which I assume is because of color resemblance (as it behaves very similar to how it responds to its own reflection).

Mine eats prepared foods (like flakes, pellets, frozen), so it doesn't even go after larger shrimp like cleaners or peppermint. It goes crazy for amphipods though.

There are a lot of misinformation about bettas around the web. Mainly that they are groupers. They are not groupers and not even closely related to them. Anthias are more closely related to groupers than marine betta is related to groupers. Marine bettas close relatives are assessors and devilfish (like blue devilfish).


OP, I had a friend who kept these upside jelly fish. They are not easy to keep in regular reef tanks. If they get disturbed, they will try to move and can get shredded by pumps or etc. Corals and anemones also sting them of they get too close, large anemones and jellyfish eating coral (like plater corals, large Trachyphyllia, etc) can eat them

Marine Betta (atleast mine) have never tried typ attack any of his tank mates.the way they hunt wouldn't favor them with fishes. Plus he eats prepared food (flakes, pallets, frozen) twice a day (in lil bit of course). They eat at 12noon and at 7pm they have a lil to munch on while I feed the corals. His focus is always to anticipate food time and not to attack tank mates. @Tripod1404, I figured it was gonna have to do with stinging cos they don't necessarily eat corals. Right now my corals are still in frag mode,I have no anemones and I dont plan on getting any. However I do understand that one day in future they'll grow...
Another thing I couldn't really find online or anywhere is their waste habit. Do the upside down jelly fish create a lot of waste? My LFS says they have something tentacles,do they also have any toxic fluids like inks. Thanks for all your input.

They are photosynthetic, so they dont create waste more than a coral or anemone of similar size. They constantly push themselves down to the surface by swimming upside down, so if they constantly do it on the sand bed, they can disturb the sand. They can sting but they dont have ink or anything.

Thanks a lot. Sounds like it's worth the shot. This would definitely be the most daring thing in my tank, but I think it's worth it.
