Alloophorus

In the scientific paper "The Trophotaeniae of the Goodeidae, a Family of Viviparous Cyprinodont Fishes" by C. L. TURNER (1937) the authors HUBBS and TURNER describe the genus Alloophorus for the first time. The species robustus had already been described by BEAN (1892) and robustus served as the type manifesting the genus.

This genus contains only one species and is therefore monotypic.

Alloophorus is a Goodeid that can get very big. It mainly occurs in larger standing waters and its appearance readily indicates that it is a predatory fish.  The females may reach a size of up to 20 cm.  Just like many other Goodeids this genus prefers temperatures within the range of 16 °C to 22 °C.

Alloophorus is omnivorous, but the larger these fish grow the more carnivorous they get, so that smaller fish can become their prey. Live-food may be necessary for successful breeding. Alloophorus robustus is nevertheless relatively peaceful towards fish that are not regarded as prey.
