Is this a Euglena protozoa?

Growing on inside pane of my reef aquarium, I believe these are the organisms producing what one perceives as "green algae" (the green ones with red "eye" spot). At least, 95% of the sample I swobbed from the inside glass pane was comprised of these organisms, and about 5% consisted of the diatom shown here.

Both images taken with 40x objective, and both cropped.
