Also called the Pike Livebearer, Pike Topminnows are the sole species in their genus and are rarely seen in the aquarium hobby. They can be seen for sale from time to time on the various aquarium auction sites. These fish have elongated jaws filled with sharp teeth which they use to capture and eat small fish, insects and tadpoles in the wild. Pike Topminnows have narrow bodies that are typically light brown or cream-colored ornamented with small dark spots along the lateral line. This species can be found throughout much of Central America in parts of Mexico, Honduras, Belize, Nicaragua and Costa Rica. Pike Topminnows tend to inhabit bodies of hard, alkaline water in both freshwater and brackish environments, including slow-moving waters and mangrove swamps.
