Children like to keep fish as a hobby

Many children like to keep cats and dogs at home as pets. However their parents will usually refuse, because a lot of effort is required to take care of these pets. The other option for the child is to keep a low maintenance pet
Turtles are fairly low maintenance, they are not easy to find.
Fish also require less care compared to cats and dogs, however they are likely to die quickly.
Goldfish and guppies are considered to be the best pets for children.
