When it comes to freshwater aquariums, some fish are consistently popular due to their hardiness, vibrant colors, interesting behaviors, and suitability for community tanks. Here are some of the most common and widely recommended aquarium fish, especially for beginners:
Livebearers (known for giving birth to live young):
Guppies: Arguably one of the most recognizable and popular aquarium fish. They come in an astonishing array of colors and fin shapes, are small, peaceful, and active. They also breed very easily.
Platies: Similar to guppies, platies are also livebearers and come in many beautiful color patterns. They are robust, generally peaceful, and active swimmers.
Mollies: Another livebearer, mollies are known for their various colors and patterns, including black, silver, and gold. They are generally peaceful and can adapt to a range of water conditions.
Swordtails: Named for the distinctive “sword-like” extension on the male’s tail fin, swordtails are colorful and active fish.
Schooling Fish (do best in groups of 6 or more):
Neon Tetras: Famous for their iridescent blue and red stripes, these small, peaceful fish are a classic choice for community tanks. They look stunning when kept in a school.
Zebra Danios: These striped, energetic fish are very hardy and adaptable, making them an excellent choice for beginners. They are active swimmers and prefer to be in groups.
Rasboras: With their distinctive dark, wedge-shaped markings and bright orange color, these peaceful schooling fish are a beautiful addition to a planted tank.
Corydoras Catfish: These small, peaceful bottom‐dwellers are excellent for cleaning up uneaten food. They are social and enjoy sifting through the substrate, making them fun to watch. Many varieties exist, like bronze, albino, and panda corys.
Other Popular Choices:
Betta Fish (Siamese Fighting Fish): While known for their aggressive nature towards other male bettas, these fish are incredibly beautiful with their long, flowing fins and vibrant colors. A single male betta can be a stunning centerpiece in its own tank or with carefully chosen tank mates.
Dwarf Gouramis: These colorful and generally peaceful fish are known for their labyrinth organ, allowing them to breathe air from the surface. They make a good centerpiece fish for a community tank.
Cherry Barbs: These active, schooling fish are known for the bright red color that males develop. They are generally peaceful and add a lively touch to an aquarium.
Angelfish: With their elegant, triangular shape and graceful movements, angelfish are a popular choice for larger community tanks. They can grow quite big and might not be suitable for very small tanks or with tiny schooling fish.
