Hydroid or Jellyfish?

[mikimoto01]

I have had what I thought were hydroids growing, but this morning I saw what looks like an upside down jellyfish ephyra. After taking a closer look at the hydroids, I am not sure what they are.

Looks like upside down jellies to me. Those would be fun for an only tank species no matter what they are.
