Moon Jellyfish in a Fishless Reef?

[...]

Hello people! (Again) I know I've been posting alot but I am just trying to put together a spectacular tank that I will like. Now, I though Jellyfish because I know they are not combatable with fish but they are closely related to Anemones (Which I have) and corals (Which I soon will have). Would it be possible to put maybe like 5 Moon Jellyfishes in my 40g? I know they requirements and all I have in the tank is a blue Lincktia, Black Brittle Star, 2 Trochus Snails, Nassaruis Snail, BTA, and later a couple more BTAs, clams and Euphyllia.

I know nothing about jellies but whenever I see them at the aquarium they are in BIG round tanks with nothing else in them. I assume the need to continually swim in a round tank and would sting other inverts and Corals?

 

[...]

Oh, I did some further research and apparently they aren't even reef safe which sucks, I might just do a clown harem or something

I looked into this years ago. The reason you see them in round tanks with little to no rocks is so they don't get torn. Being blown around our reefs would tear them on rocks and such.

It's not that they aren't reef safe, it's that reefs aren't jellyfish safe. Moon jellies are extremely fragile. It'd be a bit like putting a helium balloon, unsecured, in a room where everything is covered in ceiling fans.

 

[...]

Yeah, like I said, maybe stick to something that can thrive with reefs.

If you like a jellyfish in a type of a reef tank with fish you could look into Cassiopea sp, the upside down jellyfish. They have zooxanthellea like tropical coral and mostly stay on the sand bottom.
You do have to arrange the tank a bit to fit these jellyfish though. Low flow(very low) and figure out a way for them not to go into any overflow or pump for example.

Interesting, I'll look more into these guys.

They look good, its just hard to find care guides for them.

Everywhere I see says it is compatible, only that I need to adjust a couple things and get corals suited for the environment. The only place is Live Aquaria, which says the complete opposite.

Although I have kept them with fish and corals I would personally never recommend adding Cassiopeia to a reef aquarium. However, they are great for a specialized mangrove or sea grass system. In addition to releasing a mucus loaded with nematocysts, their polyps will sting corals and are a nuisance. It would be like intentionally adding a bunch of hydroids or majanos to your reef...

Wait, so does it effect anything else, like anemones? Would I still be able to have Inverts and fish, I have no corals at the moment and was going to have all anemones for a harem.

 

[Steve H]

I have kept them with Condylactis anemones (amongst other things) and live mangroves in a Caribbean system. In a really big aquarium I have seen them with lagoon corals and anemones. If your goal is a clown harem and anemones I would avoid them. Most host anemone species will want good water motion while the jellies will need very low water flow.

My good friend breeds jellies and builds jelly tanks. He said they are hard to feed. And they need the appropriate type of flow and temp. They’ve experimented a lot and can breed them but I think long term success is short. I think this pic is a moon jelly one.

I might just not go with a Jellyfish then. It'll save me the troubles.

This was our small Cassiopea tank. Worked well for 5+ years(until we had to close it due to a rebuilding).
We had Cassiopea, Xenia, Sinularia, Caulerpa, filefish and pyjama cardinal fish. Not the best picture, sorry for that

So it wasn’t like a SPS reef tank, but still an interesting tank I think
Just an example if you like to do an unusual tank with fish, jellyfish and some corals.

Of course you need to be aware of the risk of polyps spreading and that they burn even humans etc.

I love the tank. How much gallons was it?

Thanks! Something like 400 or 500 litre I think. So maybe 100 gallons or a bit more.
We actually ran this tank without a skimmer. But we did have a small sump beneath the DT. The return pump was the only pump, so it’s wasn’t much flow.

Their sting hurts a lot. I got stung by hundreds snorkeling
