Neon Tetra

Neon tetras are small and colorful. They display iridescent blue and red stripes, making them a popular choice. These fish are peaceful and enjoy being in groups. A school of at least six is recommended. They thrive in a well-planted tank with soft, slightly acidic water. Care is simple, with a diet of flakes and frozen foods. Regular water changes keep them healthy.

Betta Fish

Betta fish, also known as Siamese fighting fish, are famous for their stunning colors and long, flowing fins. They’re easy to care for and prefer warm water. Bettas are labyrinth fish, meaning they can breathe air from the surface. They do well in tanks as small as five gallons. Avoid keeping male bettas together due to their aggressive nature. They enjoy a diet of pellets and occasional treats like bloodworms.

Guppies

Guppies are lively and come in a variety of colors and patterns. They are livebearers, meaning they give birth to live young, making them fascinating to breed. Guppies are hardy, suitable for beginners, and don’t have strict water requirements. They enjoy flake food and can live peacefully with other small, non-aggressive fish. Regular water changes and proper filtration are essential for their health.

Corydoras Catfish

Corydoras catfish, or cory cats, are bottom-dwellers known for their playful behavior. They have armored bodies and come in various patterns. Cory cats are social fish and prefer to be in groups of six or more. They help keep the aquarium clean by eating leftover food. Corydoras appreciate a sand substrate to protect their sensitive barbels. They are peaceful and compatible with other community fish.

Angelfish

Angelfish are elegant and known for their triangular shape and long fins. They come in several patterns and colors. Angelfish need a slightly larger tank and do best in groups of at least five. They’re semi-aggressive, often establishing a pecking order. They prefer a diet of flakes, pellets, and frozen foods. A planted tank with space for swimming is ideal for angelfish.

Zebra Danio

Zebra danios are hardy and active swimmers with distinctive horizontal stripes. They are ideal for beginners due to their resilience and adaptability. Zebra danios prefer to be in schools of five or more. They thrive in a range of water conditions and accept various foods, including flakes and live options. They are peaceful and mix well with other non-aggressive species.

Discus

Discus fish are often considered the pinnacle of freshwater aquariums due to their striking appearance. They require specific care, thriving in warm, soft, and slightly acidic water. Discus are social and need to be kept in groups. Their diet includes specialized discus pellets and frozen foods. Regular water changes and high-quality water filtration are critical for their health.

Oscar Fish

Oscar fish are large and intelligent, often forming strong personalities. They require a spacious tank due to their size. Oscars are carnivorous and enjoy a diet of pellets, shrimp, and other protein-rich foods. They can be aggressive, so tank mates should be chosen carefully.

Plecostomus

Plecostomus, or plecos, are known for their algae-eating habits. They have distinctive patterns and suckermouths for clinging to surfaces. While effective at controlling algae, they can grow quite large, needing a big tank. Plecos generally get along with other fish, but their size makes compatibility important. They require a diet that includes algae wafers and vegetables.
