i have tried in vain to get pictures of these things in my wife oceanic 8 that is for her sexy shrimp,but they are so small my camera just blurrs the picture.the best i could say they look like feather dusters backwards on the glass, if i disturb them i would say they pulse away like a octopus and then return right back to the glass.i will continue to try to get a picture but i have taken about 20 allready with no luck.

By "pulse away" do you mean they free swim and then land somewhere else? If so, it sounds like the type of behavior I've seen from Cladonema jellies in my tanks (usually in the 1-2mm body-size range, not counting tentacles). They sit on glass/rocks/etc. and will swim away if bothered, but they eventually settle again.

did a gooole search for those and that is it thanks,could find little info on them though,should i get rid of them or leave them alone?

I've never seen Cladonema cause harm to anything, although I've never kept SPS in my tanks so I don't know whether those corals might react any differently to the jellies sitting on them than softies/LPS. It's also been my experience that Cladonema jellies don't tend to last, despite my attempts to cultivate them. I get blooms of them every so often and then they dissappear again.

sounds right to me. my understanding iirc, they have a 47 day life span. they attach themselves to rocks, glass etc in order to feed.

i have a few in my tank and I am not too worried about them.
