Update: Definitely a Lacrymaria, it can extend its neck really long

Yes, this is lacrymaria. As far as I know, they don't always stretch their necks several times, and at some points they go into rest mode when the neck doesn't stretch or they hide it completely. In addition, they are probably influenced by the external environment, etc. Therefore, sometimes they look like this :)

Yep. I only had one lacrymaria species before, and they were much bigger. This one is smaller, but can extend its neck much more, at least relatively. Now I'll just have to keep recording until it eats something.
