If an animal feeds mainly on algae but also eats cyanobacteria and insects, which group does this animal belong to; herbivore or omnivore?

I wonder if a fish (Random sp.) feeds mostly on plankton but also consumes cyanobacteria and some insects (Chironomidae, Simuliidae) at much lower rates, can we classify them as omnivore?

This is the method I use: Samples are preserved with Lugol, for counting I use an inverted microscope. When I know the exact area of my chamber and one field of view I can calculate the percentage of the entire sample I see with one field of view. Then I start identifying and counting the plankton. For more information see Utermöhl 1958.
