Fish

Many children have household pets whether they’re large or small. Whether it’s aquatic or non aquatic. All pets have a unique style and talent especially fish.

There are over 25,000 species of fish in the world and almost 150 species are endangered. These type of pets are cold blooded like reptiles and amphibians as they are l their body temperature. Some fish live in salt water, such as halibut and cod.

Forty percent of fish species have fresh water as a habitat. However, less than .01% in the world is fresh water. Most people of the world own a tropical fish as they are one of the most common species of fish. Unlike freshwater fish, tropical fish need a precise temperature of water. The suitable temperature would be 22℃ or lower, as having the opposite temperature slows their system down and can lead to severe stress.This can make them vulnerable to illness and other health issues.

Like humans all fish have a vertebrae, this helps them move through the water with ease. All fish have a specialised sense organ called the lateral line which works like night goggles that help then navigate in the dark or mucky water. Fish have an out stand mark of sense, touch, smell and ‘hearing’. Fish feel the same pain and suffer stress just like mammals and birds.

All animals are unique in their own ways whether they're big or small. However fish would be the best type of pet as they would never run away from you.
