Description
The Big Bend Gambusia is a small, critically endangered livebearer endemic to Big Bend National Park, Texas. Males are smaller and often display yellow fins, while females are larger and more subdued. This hardy species is primarily insectivorous and requires stable water conditions, and due to its conservation status and potential for aggression, it is best kept in a species-only tank.
