The Ultimate Classics! 5 Hardy Beginner Fish
1. Neon Tetra
Difficulty: ★☆☆☆☆ / Price: ¥50–¥100
The neon tetra is the quintessential beginner tropical fish. With their striking blue and red contrast, a school of 10–20 neon tetras is spectacular. They thrive in water temperatures of 22–28°C and pH 6.0–7.5, making them adaptable to a wide range of conditions and easy for beginners to manage. They eat readily and grow well on artificial feed. Since they are schooling fish, keeping 5 or more together brings out their true beauty.
2. Guppy
Difficulty: ★☆☆☆☆ / Price: ¥100–¥500
Guppies are prized for their colorful tails, and through selective breeding, hundreds of color variations now exist. Keeping males and females together allows breeding, giving you the joy of witnessing newborn fry—another reason for their popularity. However, they breed very prolifically, and your tank can become overcrowded quickly. For beginners, it's best to start with males only or have a separate breeding tank ready.

The red tetra, known as the "toughest fish," has remarkable adaptability—it can survive temperatures as low as 10°C without a heater. It can even be kept in bottle aquariums and small containers, making it perfect for those with limited space. The red fins add a clean, beautiful accent, and their timeless appearance never gets boring. It's no exaggeration to call them the tropical fish least likely to fail.
4. Platy
Difficulty: ★☆☆☆☆ / Price: ¥100–¥300
Platies come in an array of colors—red, blue, yellow, black, and more—and like guppies, they are livebearing fish that breed easily. They have high water quality adaptability and prefer neutral to slightly alkaline water. With their peaceful temperament, they mix well with many other fish species. They are ideal for beginners taking their first step into breeding.
5. Amano Shrimp
Difficulty: ★☆☆☆☆ / Price: ¥50–¥100
Technically shrimp rather than fish, I cannot introduce a tropical fish tank without mentioning them. They serve as the "tank's housekeepers," eating algae and leftover food while helping maintain water quality. They are peaceful and never attack other fish, and they breed easily. Keeping them alongside small fish creates a naturally balanced tank environment.

6. Corydoras Paleatus
Difficulty: ★☆☆☆☆ / Price: ¥300–¥500
Corydoras swim along the tank bottom in an adorably fluffy manner, eating leftover food that falls to the substrate. Among corydoras, paleatus is especially hardy and tolerant of lower temperatures, making it a beginner-friendly species. Their adorable habit of probing the sand with their barbels never gets old to watch. Choosing a fine-grain sand substrate prevents damage to their barbels.
7. Harlequin Rasbora
Difficulty: ★★☆☆☆ / Price: ¥150–¥300
The harlequin rasbora is striking with its orange body and wedge-shaped black markings. When schooling, they shimmer with light refraction, adding color to your tank. They prefer slightly acidic soft water, and keeping them in a tank with soil substrate keeps them in optimal condition. They have a peaceful temperament and mix well with other fish. Keeping them with neon tetras is a classic combination.
8. Golden Honey Gourami
Difficulty: ★★☆☆☆ / Price: ¥300–¥500
The golden honey gourami is brilliantly yellow throughout its body and is a member of the gourami family, characterized by long ventricular fins resembling antennae. They swim actively from the water surface to the bottom, creating movement and interest in the tank. They have a peaceful temperament and mix well with many other species. They possess a labyrinth organ (auxiliary breathing organ), allowing them to breathe air directly from the water surface, making them tolerant of low oxygen levels—a beginner-friendly advantage.

9. Otocinclus
Difficulty: ★★☆☆☆ / Price: ¥300–¥500
Otos cling to the glass and plants, eating diatoms (brown algae), making them a classic algae-control fish. They have a calm temperament and do not bother other fish. However, they can be difficult to train to eat artificial feed, so if algae becomes scarce, you'll need to supplement with pleco tablets or similar foods. Keeping multiple individuals makes management easier and increases algae removal effectiveness.
10. Betta
Difficulty: ★☆☆☆☆ / Price: ¥300–¥3,000
Bettas are prized for their large, beautifully flowing fins and can conveniently be kept alone in tanks as small as 30 cm. With their labyrinth organ, strong aeration is not necessary, and a sponge filter with gentle water flow is ideal. However, males are highly aggressive with each other and must always be kept individually. Each individual has unique patterns and colors, and finding "your own special betta" is one of the unique joys of keeping them. For disease prevention, please also see our Betta Disease and Medication Guide.

Setting Up Your Tank for Success
Here's a summary of basic equipment for keeping tropical fish long-term.
Equipment
Guidelines
Tank size
Small tanks (30–45 cm) are easiest to manage
Heater
An auto-heater set to 26°C is best for beginners
Filter
Hang-on filters are easy to install and maintain
Substrate
Sand or soil are standard; choose based on fish preference
Lighting
Run 8–10 hours daily; a timer is convenient
When first setting up a tank (the first 2–4 weeks), the key to success is to keep a few "pilot fish" such as red tetras or neon tetras to establish beneficial bacteria before adding more fish. For managing high summer temperatures, please also refer to 7 Ways to Control Water Temperature for Tropical Fish.
