American Flagfish (Jordanella floridae)
This is one of the hardiest fish you can find in the hobby and does well in a variety of setting ranging from a community aquarium to outdoor ponds. They are known for their great algae controlling abilities! This New World Killifish has colorations that resemble the US flag, hence the name American Flag Fish (some call it the Florida Flag Fish).
Size is around 1-1.5 inches.
