Do not keep your fish into small aquariums

The truth is that fish can’t be happy into small aquariums because they need more space to swim, numerous items to explore there and other decorations. So, if you decide to have a fish as a pet try to buy a bigger bowl, because otherwise, you may lose it faster than its normal life span. 

Reddit user and vet whereistherumgone said that “The idea that fish can be kept in bowls comes from the fact that people in eastern Asian countries like Japan would temporarily put their fish on display in bowls to show off to guests, and housed them in large ponds most of the time. Westerners assumed such small containers were suitable to house fish in and this is still wide-spread today.”
