The optimum temperature for reproduction ranges from 240C to 340C but the fish can survive at freezing temperatures.
The fish frequent areas especially suitable for the mosquito larvae. It lives and multiplies in ponds stocked with larger fish provided the pond is shallow and has protective vegetation for refuge.
