2. Guppies
Guppies are another excellent option for novice aquarists. They are hardy fish that come in a variety of colors and patterns.

4. Corydoras Catfish
Corydoras Catfish are bottom-dwellers that help keep the tank clean by scavenging for leftover food. These peaceful fish are ideal for community tanks and get along well with most other species. Corydoras are social creatures that prefer to be in groups of at least three, and they thrive in a well-planted tank with a soft substrate to protect their sensitive barbels.

Swordtails are best kept in groups and are generally peaceful, although males can sometimes be territorial.

7. Betta Fish
Betta Fish, also known as Siamese Fighting Fish, are popular for their striking colors and flowing fins. While they are often kept alone due to their aggressive nature, they can be a great choice for a single-species tank. Bettas require a well-maintained tank with a lid, as they are known to jump. They thrive in warm water and can live in smaller aquariums, making them ideal for those with limited space.

These fish have a unique appearance with their bristly "whiskers" and are effective at cleaning up algae in the tank. They are hardy and adaptable, making them suitable for a variety of tank setups.
