Herichthys minckleyi, found in the unique Cuatro Cienegas waters, has been observed displaying a unique spawning behavior. Since dominant males tend to horde all the females for themselves, smaller males have been observed sneaking into the spawning process in order to fertilize some of the eggs themselves. This behavior was observed and recorded by Ronald Oldfield. Details were published in Hydrobiologia but are behind a paywall. A description on the sneaky behavior by Herichthys minckleyi can be found on ScienceDaily.com. A video of the spawning behavior was posted on the Case Western Reserve University Youtube page.
