That is really bizarre, and theoretically nearly impossible. :lol: Some jellies can reproduce asexually (like fragging), though I don't know if Upside Downs do, and the polyp shown would have to be the product of sexual reproduction. Got pics? I'd love to see how they matured! Did you find anyone else documenting this too?

I have yet to observe them in my DT, but they seem to congregate in the return section of my sump. I'm guessing it's just too hard to spot the tiny guys in the DT with the LR, or they are getting eaten.

I had moon jellies come in on a quarantined feather duster. It wasn't doing so well, so I left it in a very still tank and a few months later, I had a "what the heck is that" moment! Sure enough, the LFS had jellies in the tank before I'd bought the feather duster out of it.

Not sure how I would have gotten jelly fish.

Are they gone now?

Will check when I get home on Sunday! Currently in Maui on vacation. Keep you posted Mindy.

Wth are you doing on Canreef when you're in Maui???

This is a good question!! I usually slide on early morning or at night when I'm exhausted.
