This Carp was caught on 18 May 2003 on Pueblo Lake, Colorado.
The second picture shows two very young fish, taken 20 August 2008 at the Fountain Creek Nature Center. I believe that the only fish in those ponds are Carp, so I assume that these are newly hatched Carp. They are about 1/4" long, too young to identify otherwise.
The third picture is a 13" or 14" inch Carp at the Fountain Creek Nature Center, on 12 March 2010.
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Cypriniformes
Family: Cyprinidae

Rainbow trout. The first one was caught on 10 September 2001, at Eleven Mile Lake. It measured 15 1/2".
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Salmoniformes
Family: Salmonidae
Genus: Oncorhynchus
Species: O. mykiss

Another Rainbow Trout, that I originally thought was a Kokanee Salmon, 14", caught at Eleven mile lake on 8 July 2011.
