Tiny jellyfish?

I have some tiny 1 to 2mm, white and clear, jelly fish (10 to 20) living in my nano(and in the filter), what are they and will they do any harm?

jpg, as a matter of interest do you use NSW or Salt Mix for water changes? I use NSW and often end up with small jelly's in the system, unfortunately they don't last to long.

Hi guys - aren't these hydroids? I am quite sure that I have read somewhere about hydroids (and they look like this)....

Hi, I use Salt Mix (Ocean Marine or something like that), I'm in JHB.
I don't know if they are true jellyfish but they swim with jellyfish type motions i.e propel them selfs the same way.

Hydroids come from certain types of live rock. I am not sure if jelly-fish would come as "hitch-hikers"....
