Unresolved jellyfish/anemone/ or what!?

i have 7 small things on my glass. ya thins cuz i have no idea wth they are! they have tentacles and seem to eat the copepods when they get close enough. my camera wont zoom in close enough to get it in focus. smaller than a grain of rice but they seem to grown fast. i remember seeing a jellyfish like sac in the aquarium after dumping in my order of hermit crabs...it was sucked into the intake before i could get it. anyone know what it could be altho i have no pic?

 

this is the only way i could somewhat show you what it looks like

hopefully the link will allow you to look at the crappy picture i made to resemble what i see

 

Hydroids?

 

pseudocorynactis anemone (google it for a pic) or a medusa stage of something? With out a pic it's a toughy.

 

that crappy pic you made looks like hydroids to me....said not to survive long in an aquarium

 

plenty of hydroids are highly invasive and do insanely well in aquariums. Enough so to make them a nuisance/coral killer.

 

awww, that's not nice

I would "guess" a type of hydroid as well..

 

My guess is a hydroid. Check out this thread, there is a great pic of one on the first post: http://www.3reef.com/forums/id/other-hitchhikers-42424.html. The pic is about halfway into the the first post.

 

Thanks guys it is a hydroid. Anyone know how to kill hydroids?
