Jordanella floridae

[gupp]

Here's another one. This is a male flag fish, they're a native killie from the southeast. As you can see the males are very colorful, females less so. They are often used in the planted aquarium to help keep it free of algae. They breed easily.  I keep a breeding group in a 10 gallon tank and a few in other tanks. They also can live year round outside in the area here.
