As you can see in the video above, these fish change color depending on a variety of factors such as who is dominant, attempting to blend in, etc. The iridescent coloration with the dark body that you see in the photo and painting are typical of males during breeding season (hubba-hubba). While on the prowl, the males establish a territory of about 1 cubic foot. If that sounds small to you, that’s because it is a matter of perspective. This Pygmy Sunfish only gets to a length of around 2.5 centimeters—that’s just under an inch! The male spends its time dancing throughout its territory to attract the attention of the ladies by wiggling their fins like glitter-gloved-jazz-hands, stop completely for a few seconds, and returning to the wiggle. The females have it easy, casually swimming through territories, spawning, and leaving the eggs under the males care until they hatch roughly 3 days later.
