Anybody know what kind of jelly this is? So far I've only seen them get about 1 inch in diameter.

:welcome: to RF. do you have any other pics and how did you get them??

 

[user 26995]

those are really cute. Do you have them in your system? Or did you see them somewhere else? You would be surprised at what you might find in your tank that you didnt know was there.

These showed up about 4 months ago as tiny dots drifting in the sump on my seahorse tank (which contains live rock). I thought they were interesting, so I protected and fed them and they started growing. I'll see about getting some more pics posted. I do love seeing what surprises come out of live rock!

I've seen some one else here on RF had found a type of jellyfish in his tank or sump also. They were not the same as what you have. I think yours are beautiful.

Do you buy your wc water? Do they filter ocean water?

No idea, pretty cool though.

I use Instant Ocean salt and tap water. I'm assuming the jellies came in on live rock, although I hadn't added any new rock for quite awhile. I don't know what else to think.

I have them in a refugium. These aren't the kind of jelly that needs a round tank.

A couple more pictures of blue jellyfish


Here's a side view of the blue jellyfish.

Blue jellyfish swimming. It's not easy to get good shots of these guys. (My significant other took these pictures.)

Those are so cool.

I've learned these jellyfish are in the genus Cassiopeia, the upside-down sea jellies.

 

[mercenary-grunt]

Ahh I should have known. I recignise it now.

I'd say they are a bellybutton jellyfish

 

[Brent&kitty420]

But it does look like the Cassiopeia as well

 

[Boomer]

It doe not even remotely resemble a Bellybutton

 

[Brent&kitty420]

[Boomer]

A Blue Button and Belly Button are the same thing ;-)
