Tilapia is more commonly known as the type of fish served in restaurant rather than the one kept in aquariums as pet. However, that doesn’t mean that fish tank hobbyist do not fancy having the fish around as there are some who would rather keep them in large viewing tanks rather than putting them in ponds. They are also easy to keep without needing much attention which is why they are popular among beginners to freshwater fish since some common mistakes are unlikely to harm them.
