Mini Jellyfish?

[Spotted Leopard]

Well this was a long time ago. But I never did get my question answered....

About 1 year ago, I had an invasion of these little jelly like creatures. They were 1 mm in diameter and 2 mm in height. They had little 1/2 mm tentacles. The usually swam around or stuck onto the surface of the glass. The LFS didn't know what they were. To me, they looked like really tiny jellyfish. They were too small to get a picture of.

Does anyone have any ideas to what these things were?

most of the time little jellyfish are called hydroids
