Goldfish were developed by the Chinese over a thousand years ago from a species of Carp. This would indicate to me that the Goldfish has no natural "ecosystem" of its own in which it evolved. However I would assume that the ecosystem to suit one would be that of the natural habitat of the fish from which the goldfish was derived. Namely the Prussian Carp (Carassius gibelio). These fish naturally inhabit the temperate lakes, Ponds and Slow moving rivers of Asia. So their 'ecosystem' would be that of a temporate lake, pond or slow moving river.
Maybe a room with some sun light but not too much of it, a small 2 or 3 gallon tank WITH a filter, they live a lot longer with one than without. Some pebbles for the bottom and a fake plant. Also maybe a play mate for company :)
No. Goldfish do not inhabit that same environment as killer whales do. Goldfish are not marine animals.
An ideal environment for kids is to play and no one stops them and there is no school.
Milkfish can be eaten. It is one of the staple fish in the Philippines. Goldfish is a fish for aquariums also ideal for pets
A goldfish uses smell to find their food whether they are in the wild, or an aquarium environment
Either a tank or pond of at least 30 gallons is a suitable environment for a goldfish.
Goldfish naturally are foragers and will eat both what they are provided and what they can locate in their environment, like algae or growing plants.

It is possible that a goldfish would nibble at Hornwort if it is available in its environment but I would not expect it to be a major part of a goldfishes diet.
By 2011, the population will be almost seven billion. The world is over populated. The ideal population for the environment is less than two billion people.
