Found it on the inside panes of the glass on my new reef aquarium. Have hundreds if not thousands of them. I guess they feed on copepods? I have a bloom of copepods due to a bloom of diatoms.

Is this vorticella?

The myonemes seem to be connected at the branches leading into the main stalks, so probably not Carchesium or Pseudocarchesium.
Lipped zooids, so not Entziella.
That leaves Zoothamnium and Myoschiston (a marine peritrich, epizoic on crustaceans like your copepods). Looking closely at the second-last image, it seems the myoneme continues into the lower stalk, so I would say this is probably Zoothamnium.
The enlarged zooids we see here are typical of Zoothamnium.
Congrats on the fabulous images!
