Has anyone considered a Betta fish that someone let loose in a pond. Burger may have guessed it right in his previous post. The coloration is different (and I am not familiar with the exact class they belong to), but the flowing fins, body shape, and mouth all fit into my hypothesis. Lots of folks throw aquarium fish into ponds and lakes.
Just throwing something out there for thought. Any thoughts???

edit: The Betta splendens, Siamese Fighting Fish, are a member of the Labyrinth Fish Family. Betta antoni is a member of the akarensis group and is distinguished by its black lower lip and black chin bar, and slim body profile.
Betta mandor is a member of the foerschi group and can be identified by its slim shape and presence of two red bars on the gill cover.
Betta krataios is believed to be a member of the Betta dimidiata group and has a distinctive iridescent blue operculum, and more predorsal and lateral scales than other members of the group, as well as lacking the extended fin rays seen in some other species in the complex.
Betta ideii differs from other species in the Betta unimaculata group in having a characteristic orange marking between the front of the eye and the upper jaw. Betta compuncta is also a member of the unimaculata group and has a distinctive black reticulated pattern above the base of the anal fins of females and young fish, or a black patch in males. There's also a yellow-orange marking on the tail of females of this species.
Betta uberis is a member of the coccina group and has distinctive green streaks on the dorsal, anal and tail fins as well as an iridescent green mid-lateral spot, which is seen in most members of the species group.
Interesting fish to ponder over Bruce. Could it be a Betta who lost its vibrant colors due to its environment, or could it even be a hybrid. My curiosity is at an all time high (that or my meds for strep throat have ME at an all time HIGH, :p )
