Keeping an aquarium is a lovely hobby and one that everyone can enjoy. Whether you have a couple of fish, a little, or a lot, you will enjoy a healthy aquarium that is filled with life. Aquariums are showcases for some of nature's most spectacular species. We all appreciate the beauty of the fish, but how many of us are also fascinated by the creatures beneath the water? Many fish came about as the result of hybridization between existing species. If you are planning to have a pet fish, here are some beautiful species of fish that will suit your aquarium.

Flowerhorn Cichlid

With the Flowerhorn Cichlid, the male has a very showy bright red "collar" around the dorsal fin, while the female has a dull brown "collar" with a darker shade of red on the edges. The Flowerhorn Cichlid is native to Lake Tanganyika and is found in a limited area of the lake, so I guess they aren't doing so bad with their name.

Zebra Danio

The zebra danio is a beautiful fish that can be found in the aquarium trade, but that doesn't mean it's not worth more than just a casual glance. Many aquarists are unaware of how gorgeous this fish can be, and as a result, it has been a bit overlooked in the aquarium community.

Fancy Guppies

Guppies are one of the most popular tropical aquarium fish, and for a good reason. They are extremely hardy, and they are very easy to keep in an aquarium (well, mostly). They also have a ton of personality and are a great addition to a large aquarium setup.

Duboisi Cichlid

Duboisi Cichlid, or Synodontis microlepis, is a small cichlid with a beautiful color pattern. The male Duboisi gets its name from the pale-colored spots on the body that resemble the dress of the 20th-century Parisian socialite Madeleine Dubois. The female Duboisi, on the other hand, gets her name from the French word for mouth, and the shape of its mouth resembles a beak.

Harlequin Rasboras

The Harlequin Rasboras (Rasbora Harlequin) is an aquarium fish species. They are a genus of small fish that are found in tropical and warm-water lakes. The Harlequin Rasboras is one of the smallest and most colorful of the Rasboras and are a good community fish with peaceful personalities.

Neon Tetra

The neon tetra is a popular choice among beginner aquarists due to its hardiness and ease of keeping. It is a tiny, schooling fish that is generally sold as a community tank fish. In its natural setting, these fish can be found in rivers and streams, where they will readily devour smaller fish. Since they are not a picky eater, they are also a great choice for a messy tank and a small budget.

Bluefin Notho

The Bluefin Notho is a beautiful little fish. It is a member of the Sciaenidae family, also known as the "scorpion fish," and they come from the Pacific Ocean. They are found in deep, warm waters and can inhabit reefs, kelp forests, and even mangroves! They tend to be small but are very hardy and will grow up to about 6 inches in length.

Keeping fish tanks can be a fun hobby that people get into. But alas, keeping a healthy tank isn't easy. There are many factors to consider when keeping fish in an aquarium, including the types of fish you have, how many algae are present, and how often you clean the tank. But perhaps the most important factor is the size of your tank. If you have a small tank, for example, you won't be able to keep too many fish, and if you have a large tank, you won't be able to keep enough fish.
