Pay attention to fish relationships as well

Even though you see a lot of fish groups in different animal documentaries you should know that they form fish communities of the same species, they are not different. So, if you want a fish as a pet you should know that they cannot get along with other species because each creature has different needs, and some can become aggressive.

“For example, Lake Tanganyika cichlids can only be housed with other cichlids of the same area of origin. The different varieties of these cichlids each have their own unique habitat requirement,” says Dr. Ogle.
