Unknown Phytoplankton ID - Pelagic Flagellate

[chcgregg]

Hi there, have had slightly cloudy water and took a sample to find this guy. Not sure what type of algae this is. It has at least 2 Flagella, and is present when the lights are on. No sign of slime. Moves quickly as well.
If anyone has any idea what genus this belongs to, that’d be great!

Yeah! Quite possibly!
