It possesses great adaptability and can survive in living environments with a low oxygen level, saline water, and a high temperature approaching 108 ℉ (42 ℃) for a short period.

Aquarium story of mosquito fish
Seeing that introducing mosquito fish is effective in dealing with mosquitoes. As a result, mosquito fish are introduced to reduce the population of mosquitoes, during the 1920s-1950s, mosquito fish were used to eliminate malaria in Sochi, Russia. Then a monument was constructed in Sochi to commemorate it. Until now, mosquito fish are still a biological control method to deal with mosquitoes in some places.
Actually, mosquito fish do make sense in reducing the population of mosquitoes. However, mosquito fish thriving will cause ecological impacts. As mosquito fish flood in, it can be a threat to indigenous fish, leading to the reduction or even disappearance of indigenous species.
