They are kept in a fish shop or aquarium or even a fish tank
Many different types of fish can be kept in fish ponds so long as they are relatively small and can adapt well to the environment. The most common of these fish are koi.
Tropical fish are normally kept in a heated aquarium. Goldfish (and similar species) are usually kept in a coldwater aquarium, or in a goldfish bowl. Where fish are reared commercially for eating: salmon, trout, etc. they are kept in floating fish hatcheries that are usually found in Scottish sea-lochs.
Fish are typically kept in aquariums or fish tanks. These containers are designed to provide the necessary environment for fish to thrive, including appropriate water conditions, filtration, and space to swim. Some fish are also kept in outdoor ponds or bodies of water.
Fish do not get fat. They do not over eat and they always exercise if they are kept correctly. It is insufficient swim space and bad water care/hygene that usually kills fish in aquaria.
No fish should be kept in a bowl. They should be kept in at least 10 gallons of water but usually more depending on how many fish you have and how many you have. A good general rule is for every inches of fish you should have 1 gallon of water keeping in mind that they will grow.
No, they need air, filtrtion and regulated temperature. Not many fish can be kept in bowls.
Only 1. Usually a Betta is all that is kept in a 3 gallon tank
Mollies are tropical fish and should be kept above 70F. Goldfish are coldwater fish and should be kept below 70F. They should NEVER be kept together.
Loner fish will often fight for territory when kept together. Fish that do not do well with other fish, like Beta fish, will often fight with other fish for territory.
