So, found these in my sump... 2 vids, one of jellys in the sump and another when I caught 3 in a glass... deffo jellys I'm sure, but which ones and how?


 
Here's a close-up from the top...

Nice. If they were in your sump they may, emphasis on may, be a non photosynthetic type that feeds on passing plankton. Other than that I'm no help, but they should love your feather star tank
 
Nope... had confirmation today. Dropped into my LFS... they had a tankful, some up to 2 inches across and definitely jellies! They had some appear in their sumps after a shipment of seagrass... I didn't have my phone with me tho, but have asked her to send me a pic. Below is a pic I just took... look at the one on the left, you can clearly see the guts and 'tentacles'... not just a bell as in hydroids. They aren't photosynthetic ones either, the tank in the LFS is being fed with reef roids and has no lighting... they are multiplying like anything!! Also took another vid or two, which I'll post after it's uploaded.

If they came in on seagrass then they will be from cebu if you want to narrow your search a little. Given in the lfs (bs ?) vid they look to be on the glass rather than free swimming, they could well be baby cassiopea sp as these are commonly found in seagrass.
