Ray-finned Fish (Needs ID)
12 November 2016
Avondale Park
Denton, Denton County, Texas
In between rainfall events a large school of some kind of small freshwater fish measuring up to three inches in length was trapped on one side of the creek and there they remained for about one week until the next rainstorm came and provided enough water for them to continue their journey downstream a few miles to eventually reach Lewisville Lake. They schooled the entire time they were present in the pooled part of the creek awaiting the next rainfall. There were easily several thousand such fish and provided (while the feast lasted) food for the big birds that smartly visited the creek during the period they were present. In the many years we've observed this part of the creek we'd not witnessed this particular small fish and their behavior. The large size of the school was notable. So we're looking to identify what kind of fish this was. Your assistance is greatly appreciated. Thanks!

Male's dorsal fin orange with black margin (see second photo attached). This fish was abundant in the small river below the Salto El Limon (mostly females that lack the black and orange dorsal fin coloration). Compare photos in Torres-Pineda et al 2019: https://www.researchgate.net/figure/Limia-zonata-Left-male-right-female_fig1_331209862) who also report on the skewed sex ratio. This is the only Limia species recorded at this locality, and the Samana Peninsula in general, by Weaver 2015 (https://scholar.colorado.edu/cgi/viewcontent.cgi?article=1071&context=ebio_gradetds). The fish we observed were attracted to us and picking at our skin.
