But which one?

I think the algae is food and not zoochlorellae. I can't decide what form the macronucleus is. Apart from the algae it seems to be colourless.

I'm hoping for Stentor muelleri

Amazing videos! I've seen these little guys before, but I was unable to identify them Internet pics don't help a lot either, but my guess would be S. roeselii. Take this with a pinch of salt, as I couldn't see the boys' macronucleus and I'm a little rusty at this <:)

Hope this helps,

I have just found some S.roeselii within loricas and they look similar but do not have the algae that these do, and the worm like macronucleaus is clearly visible where in this video it is not.

Thanks Tenshi for your input.

Besides the incredible pictures, this document helped me begin to identify stentors. https://www.canadiannaturephotographer.com/stentor.html

Thanks Crusty as you say the photos are amazing and the website is packed full of information.
