The Pacific blue-eye can be distinguished from the noxious introduced eastern mosquitofish ( " Gambusia holbrooki " ) by its forked tail fin.

The San Marcos gambusia has only been identified in a 0.6-mile ( 1-km ) stretch of the headwaters of the San Marcos River.

Gambusia are known predators of tadpoles of other closely related frog species, such as " L . aurea " and " L . dentata ".
26.
Other species to be removed from the San Marcos River include the San Marcos salamander, Texas blind salamander, fountain darter, and San Marcos Gambusia, a small fish.

The so-called mosquitofish, Gambusia affinis, which will be confined to the plants, multiply rapidly and are considered a vacuum for larvae, consuming hundreds an hour.
28.
In the wild, some rainbowfish populations have been severely affected by the aggressive introduced eastern mosquitofish ( " Gambusia holbrooki " ), tilapia cichlids, and pollution.

The acclimation of the " Gambusia affinis ", a larva-eating fish used to combat malaria is attributed to his son, parasitologist Sad?de Buen Lozano.
