Conjoined Peranema squirming as they pull apart from each other. Were they dividing or conjugating?

[taxonomy:genus=Anisonema]
Anisonema is gliding euglenid with two prominent flagella, the longer one trails along behind the cell. Here, two cells have either just finished dividing, or are just leaving conjugation (leave a comment if you know which!). At first I wondered what was this cell with four flagella, before realizing that it was actually two cells in the process of separating.
From a sample originally collected 3 days ago.

[taxonomy:genus=Trachelomonas]
The "durian flagellate" Trachelomonas is an euglenid with a single thick flagellum emerging from a cell body that is surrounded by a spiny shell (lorica). The cell swims rapidly through the water. The swimming appears to be driven by a helical beating of the flagellum wound around the cell body.
