    Found this bad guy on my neon goby - so just before I killed it I took some photos (they kill fish so I had to kill it).

    For comparison how different an organism looks like under transmitted light as opposed to reflected light, the below two pictures were taken with a Canon 1DX + MP-E 65 + 600RT Flash at 3.5:1 and 5:1 magnifications:

    Amazing pics! Excuse my ignorance but what were the camera settings? What is FLUO-C4 and POL?

    Depends. On the last two photos I was at F6 and F9 or so. Manual mode. Shutter was at 1/200 I think. FLUO-C4 is the name I assigned to my fluorescence cube in compartment 4, which has excitation spectra of 330-480nm and a long pass filter at 496nm. POL is polarized (cross polarizers).

    The isopod was approximately 6mm long.
