    Most people think of a cardinal tetra as something with red and blue stripes. When using epi-polarization, one gets quite a surprise.

    Very Very nice!! Thanks for sharing @LikesFish!
    Can you perhaps explain how you achieve the epi-polarization effect under microscope?

    I use my fluorescence arm and metal halide light source but instead of using a fluorescence filter cube I use a 50/50 split cube, and polarizers in the light path.
