Kinds of Fish You Can Keep in Aquariums at Home

These are the fishes you can keep in aquariums safely and easily.

Having an aquarium at home is a good, relaxing activity. Watching your colorful pet fishes swim around and play with each other adds life to your room. While there is nothing wrong with just getting a goldfish, perhaps you’re interested in learning more about the other kinds of fish you can keep in aquariums at home.

All fishes are different. And before you go about and get every fish from this list and throw them into a fish tank together, do your research and make sure the fishes you plan on getting are compatible and can survive and thrive in the same conditions. Also, before adding new fish to your aquarium, it is recommended to quarantine fishes separately for at least a month to prevent the spread of diseases.

Fish Species You Can Keep as Pets


Angelfish are some of the most recognizable fishes on this list. They can grow up to 8 inches in length and come in a variety of beautiful colors and patterns. Feeding is easy as they can eat anything from live feed to frozen fish food. They are the ideal fish to keep if you don’t plan on housing smaller fish with them, as angelfish can be aggressive and territorial towards them.


Danios are some of the easiest fishes to care for beginners. They are very resilient, hardy freshwater fish and can easily survive various water conditions. They only grow to about 2 inches and are schooling fish. Since they are schooling fish, they should be kept in groups as if left alone, they can get stressed very easily.

They are super energetic and fun to watch, but always keep a lid on your aquarium as this fish species is known to jump out of the water! Danios have a very simple diet and can live happily on fish food and feed on worms and insects.


This fish species is tiny, only growing to less than 2 inches tall. They are some of the most beautiful fish to look at and also very easy to care for. Species of tetras like neon tetras, cardinal tetras, and black neon tetras are easily found and make great pets. Tetras also love living in groups, and their diets are straightforward. You can feed them anything from fish flakes to some blood worms and brine shrimps.

Betta Fish

Betta fish are the most beautiful fishes to keep, in our opinion. Their small size, different colors, and simple diet and care requirements make them one of the best fish species to keep for beginners. The only thing to keep in mind is that they are aggressive in nature, and male bettas need to be kept away from males of the same species. Betta fish can grow up to 3 inches tall, and their diets are simple too. Although they prefer live feed, they can easily thrive on fish flakes and frozen foods.


Also known as million fish and rainbow fish, the guppy species are the hardiest fish you can keep as pets. They aren’t very picky in their diet and can eat anything from fish feed to fish flakes to small crustaceans. These fish can also survive unfed for over a week. The only real issue with keeping this species as pets is that guppies love to reproduce. So, if you don’t want guppies to breed crazily in your aquarium, it is a good idea to either keep all male or all female guppies.
