Florida Flagfish
Jordanella floridae
The Florida Flagfish is a small native freshwater fish known for bold breeding colors and its appetite for algae.
Florida Flagfish live in shallow vegetated marshes, ponds, canals, and slow streams across much of the state.
They tolerate warm water and low oxygen better than many fish, but healthy aquatic plants and clean shallow edges remain important.
