Brook Silverside (Labidesthes sicculus) swimming in Lake Elizabeth, (Twin Lakes, Kenosha County) WI. I have always enjoyed illuminating these fish at night and seeing the bright colors they reflect, but it was tough to hold a flashlight in one hand and focus a big camera with the other. I may also have had a dog on a leash. And there were mosquitos. Shot with a 90mm macro lens. Surrounding area darkened and desaturated in Photoshop.
