Mickey Mouse platies are small, colourful, and easy to care for. They give birth to live babies, so you might even see tiny fish swimming around. Their tail has a pattern that looks like Mickey Mouse, which makes them look adorable. A 10-gallon tank is enough for a small group. They are playful, hardy, and perfect for beginners.

Guppies are one of the most popular aquarium fish. Male guppies are bright and colourful, while females are bigger and lighter in colour. They like living in groups, which makes your tank lively. Guppies are also livebearers, so you may see little baby guppies if you have both males and females. They are easy to feed, strong, and a lot of fun to watch.

Neon tetras are tiny but very bright, with blue and red stripes. They love swimming in schools, so having six or more creates a stunning display. They are peaceful and get along well with most other fish. A 10- to 20-gallon tank is ideal. Planting a few decorations gives them hiding spots, which makes them feel safe and happy.

Zebra Danios are small, energetic freshwater fish known for their distinctive horizontal stripes and impressive hardiness, making them one of the best choices for beginners. Growing to about 2 inches, they adapt well to a wide range of water conditions and are remarkably resilient, even in new or less stable tanks. These peaceful schooling fish thrive in groups of five or more and love plenty of open swimming space. Their active nature, simple care needs, and ability to coexist with many other species make Zebra Danios a lively and low-maintenance addition to any community aquarium.

Tiger barbs are full of energy and fun to watch. They have bold stripes and a bit of a mischievous personality.

Tiger barbs come in different colours like albino, green, and fluorescent varieties.

White cloud mountain minnows are peaceful and easy to care for. They can even live in cooler water, which many tropical fish can’t. They enjoy swimming in groups and do well in community tanks.

Harlequin rasboras are small, peaceful, and beautiful. Their red bodies with a black mark on the back half make them stand out. They like living in groups of six or more and do well in planted tanks.

Glowlight tetras are peaceful and easy to care for. They have a silvery body with a soft red-gold stripe from head to tail. They swim in small groups and create a glowing effect in the tank. Even a 10-gallon tank is enough for a small school.
