Clownfish With Jellyfish

[Zach Vs Ponies]

In my opinion, I feel that most jellyfish tanks are way too small, with not enough water flow, and have changing lights (which I feel stresses the fish). But that's my opinion. My question is, are clownfish really protected by the stings of jellyfish? When asked this question, a viewer of this video I was watching that had a clownfish in a jellyfish tank responded with this:

Clown fish have a layer of mucus that makes them immune to the jellyfish stings, I've been waiting for someone to ask that question.

I have been looking to see what the clownfish mucus layer actually protects it from (obviously, I know anemones, but I was seeing if it protects them from other things), but have been unable to find any information. I was hoping someone could tell me if the mucus that protects clownfish from anemones also protects them from jellyfish.

Thanks.

PS: In no way do I plan on housing any clownfish with a jellyfish. As stated in the first little bit, I don't feel the design of the aquarium is fit for a clownfish.


The video: I kind of felt bad adding a link to someone else's video, so I decided to remove it. If you would like to see it, I can PM it to you. Sorry.

I had a breeding pair of occ in a 20g with some upside down jellys and they stopped beeding. I moved them and they started to breed again

Also, the mucus layer takes a while to build up, that's why you see the clown brushing against or moving in and out of the anemone for at least a few days before it actually moves in. They do this to build up their mucus layers and a tolerance to the anemone sting. Putting a clown in with a jellyfish is not a good idea at all because the clown will have very little control over when it is getting stung.

There are a few other reasons I disagree with the current trend of putting clown fish in with jellyfish (and I can guess which aquarium this is in).

1) These tanks are generally way to small for clowns in the first place
2) Fish generally benefit from somewhere to shelter or hide from predators, being out in the open with no where to hide is very stressful for a lot of reef dwelling fish. Obviously in a jellyfish aquarium there will be no rockwork or places to hide.
3) Clowns require a stable temp of around 25C, this is warmer than the ideal temperature for moon jellies (which I guess is the jelly in the video?)

In short, if people want to keep fish they should get a fish tank, if they want to keep jellies they should get a jelly tank. I don't know why people would want to put them together anyway, it doesn't look very natural.
