Mosquitofish

Gambusia affinis

Description:

Tiny fish. "Mosquitofish are small in comparison to other fish, with females reaching an overall length of 7 centimeters (2.8 in) and males at a length of 4 centimeters (1.6 in). Females can be distinguished from males by their size and a gravid spot at the posterior of their abdomen." - Wikipedia

Habitat:

Shoreline of small lake.

Notes:

"The name "mosquitofish" was given because the diet of this fish predominantly consists of large amounts of mosquito larvae, relative to body size. Mosquitofish were introduced directly into the ecosystems in many parts of the world as a biocontrol to lower mosquito populations which in turn negatively affected many other species in each distinct bioregion." - Wikipedia

Cindy I am not sure if these are the same. Have you heard of mosquito fish? They are added to some man made lakes here to control the mosquito population. The scientific name is "Gambusia affinis"
