Further south, the golden topminnow inhabits the Lower Coastal Plain and is commonly scattered throughout Florida.

The golden topminnow was observed feeding on small proportions of Macrophytes (aquatic vegetation) and a much wider array of aquatic invertebrates, including Gastropoda (snails/slugs), large quantities of Ostracoda (seed shrimp), Ephemeroptera (mayflies), Coleoptera (water-beetles), and Chironomidae (non-biting midge flies).

Some major human influences to the golden topminnow population include habitat pollution and the conversion of marshlands and brackish water for agricultural purposes.

[citation needed] The golden topminnow breeds throughout the spring and on into the summer months from April to July, and sometimes as late as September.

Eggs are released individually and deposited on the roots of floating plants or on other fibrous material by the female, where afterwards they are fertilized one at a time by the male.

After hatching the larvae rest on leaves or on the bottom and begin to grow quickly reaching maturation after 10 months.

There is no current management plan specifically designed for the golden topminnow due to the fact that it is not listed as an endangered or threatened species.
