Detailed explanation-1: -The population ranges at least in the tens of millions, and those released into the wild can breed to the point where they become pests. Lake Ontario alone has at least 50 million goldfish, descendants of pets released into the wild.
Detailed explanation-2: -Goldfish are classified in the phylum Chordata, subphylum Vertebrata, class Actinopterygii, order Cypriniformes, family Cyprinidae.
Detailed explanation-3: -If released into the wild, goldfish can group up into what’s called a school. But they don’t need companions to be happy in captivity and are fine if kept separately in a tank. Because they’re not an aggressive species, they can be paired in a tank with fish that aren’t vastly different in size.
Detailed explanation-4: -In the wild, goldfish can be found in slow-moving, freshwater bodies of water. As with their close relative the carp, they thrive in slightly murky water. In captivity, an aquarium with live plants and a dirt bottom is ideal. Bi-weekly water changes are a good idea as a goldfish tank is hard to keep clean.
