Blue blubber jellyfish

[ml708]

I'm planning to put a large circular porous basket in my reef tank to keep some of these jellyfish.

But before I do so, do they have a painful sting? I have read conflicting reports ranging from painful but not deadly to non noticeable.

I'm planning to feed them mysis shrimp, clam max and beta brine. Is that a good enough diet?

Finally do they shed stinging cells throughout the water? I'm concerned because they will be sharing this water with my fish.

The sting can be painful, but it varies from person to person. You can get a rash or have allergic reaction to the sting.

These jellies need to be at the top of the tank for them to do well as they use the light for photosynthesis. They get there nutrition from food provided by the algae but thats not enough for them to survive. the also need to have access to the lower portion of the tank since thats where they also feed on plankton after sunset.


Your diet seems good, you have to make sure they can get to the food and your livestock dont get in the way or they will become dinner.

Also the water temp should be around 77 or so degrees F.

What size tank are these going in? There bell can reach up to 16" wide.

They will be in a 100 gal. Unfortunately I understand that they have really short lifespans of something like 10 months. Can they live longer than that?

Is it also possible to breed them? Do they reproduce sexually or by budding?

Actually there lifespan is only a few months in captivity and up to 10 in the wild.

Im not sure on breeding.

I believe we got our information from the same website lol.

Have you kept them before though?

I didnt but the reef store I worked did. The owner had them in hos 600 gallon display tank. They were really cool, but they dont last very long unfortunatly. the moon jellies can live for over a year depending on the size tank and filtration. Those are cool guys too. Most jellies only last a season.
