Can mini-jellies hurt your fish?

I have a hydroid jelly in my tank too. 
Here's a video of it pulsing (you have to look just above/to the left of the shrimp- the actual jelly is out of focus because it's so tiny, but you can see it moving): http://members.aol.com/deepoceanred/squishie.avi

If so, they don't have fully formed nematocysts like other jellies do, so I wouldn't worry about your fish right now.
When they get larger, they will be able to hurt smaller fish IIRC.
They are symbiotes and get the majority of their nutrients come from zooxantallae, IIRC. They do really well under MH lights, although mine are fine under 20k 18w flourescent right now.
They can get large...I've read anywhere from 8-12" across full size, but largest I've seen in my LFS was about 4" across.
They do best on soft substrate and low flow.
I have 63 of these guys in a 10gal tank...they just started spawning off a piece of LR like popcorn. For flow I've got a RedSea Nano filter (3gph) which works great..not too much flow, but enuff to keep water movement.
Every 3 days I feed 1 drop of coral/clam concentrate food.
They won't do well in a tank with lots of water movement as getting knocked around will hurt them...they are very fragile.
If they *aren't* upside down jellies all I can say is 'Good Luck' Everything I've read about other species shows that they do best in specialized tanks called 'Kreisel' tanks. You can buy them, but be prepared to spend a few grand. Regular jellies can't touch stuff..it'll hurt em...the kreisel tanks set up special flow patterns that keep em in the center of the water column...a google search will show ya
Hope some of this info helps!
