Betta fish, also known as Siamese fighting fish, are among the most popular and beautiful freshwater fish kept as pets. Their vivid colors, long fins, and unique personalities make them a favorite for aquarists of all experience levels. But despite their hardy nature, bettas require proper care to thrive.

In this ultimate Betta Care Guide, we’ll cover everything from tank setup and feeding to health and behavior — so your betta lives a long, vibrant life.

🌿 Why Bettas Make Great Pets

Bettas are low-maintenance, intelligent, and full of character. Unlike schooling fish, they can live alone, which makes them ideal for smaller spaces and new fish owners. They also come in a dazzling variety of colors and tail types — from Halfmoons to Crowntails — each with its own charm.

🏡 Betta Tank Setup: Creating the Right Environment

🐟 Minimum Tank Size

Many people mistakenly believe bettas can live in tiny bowls. The recommended minimum tank size is 5 gallons (19 liters). This allows enough space for swimming and reduces water quality issues.

🌡️ Water Temperature and Parameters

• Temperature: 76–82°F (24–28°C)

• pH: 6.5–7.5

• Ammonia/Nitrites: 0 ppm

• Nitrates: <20 ppm

A heater and filter are essential to maintain stable water conditions.

🪴 Plants and Decorations

Live or silk plants offer hiding spots and reduce stress. Avoid sharp or rough decor that could tear their delicate fins. Popular plant choices include Java fern, Anubias, and Marimo moss balls.

🍽️ Feeding Your Betta: Diet and Schedule

Bettas are carnivorous and need high-protein foods.

🥩 Best Betta Foods:

• Pellets (specifically for bettas)

• Frozen or live foods like bloodworms, daphnia, and brine shrimp

📅 Feeding Tips:

• Feed once or twice a day, only what your betta can eat in 2 minutes.

• Fasting one day a week helps prevent bloating and constipation.

🧼 Betta Tank Maintenance

Regular tank maintenance keeps your fish healthy and water safe.

Weekly Checklist:

• Test water parameters

• Change 25–50% of the water

• Clean uneaten food and waste

• Rinse filter media (in tank water, not tap)

❤️ Understanding Betta Behavior

💃 Signs of a Happy Betta:

🧪 Common Betta Fish Diseases

🤔 Can Bettas Live with Other Fish?

While male bettas are territorial, they can live in a community tank with the right tank mates:

• Peaceful, non-fin-nipping species

• No other male bettas

Good tank mates include: Corydoras, Ember tetras, and Nerite snails.
