Betta Fish Myths That Might Be Harming Your Pet

Betta fish are one of the most popular pet fish out there, but they’re also one of the most misunderstood. Some common myths about bettas can actually harm their health and shorten their lifespan. Let’s clear up the confusion so your betta can live a better life.

Myth #1: Bettas Can Live in Tiny Bowls

This is one of the most widespread and harmful myths. Bettas need space—at least 5 gallons of water—to swim and explore. Small bowls can cause stress, poor water quality, and stunted growth.

Tip: A filtered, heated 5-10 gallon tank is ideal.

Myth #2: Bettas Don’t Need a Heater

Bettas are tropical fish and need warm water, ideally between 76°F and 82°F (24°C to 28°C). Room temperature water is often too cold, especially in cooler climates.

Tip: Use a reliable aquarium heater to maintain a steady temperature.

Myth #3: Bettas Can Live on Just Plant Roots

You might’ve seen vases with bettas living off plant roots. This setup is not suitable. Bettas are carnivores, and they need a proper diet of high-protein pellets, frozen, or live food to thrive.

Tip: Feed your betta a balanced diet, and don’t rely on decorative setups.

Myth #4: Bettas Are Lazy

If your betta is always resting or inactive, it’s likely a sign of poor water quality, stress, or illness—not laziness. Healthy bettas are curious and active when their environment is right.

Tip: Keep the water clean, warm, and enriched with hiding spots and gentle currents.

Myth #5: Bettas Can’t Have Tank Mates

It’s true that male bettas are territorial, but they can live with certain peaceful tank mates like snails, shrimp, or non-aggressive fish—if the tank is large enough.

Tip: Do your research and always monitor for signs of aggression.

Final Thoughts

Bettas are hardy, beautiful pets—but only if they're cared for properly. Ignoring their needs because of outdated myths can lead to unnecessary suffering.

Give your betta the environment and attention it deserves, and you’ll have a vibrant, happy fish that lives for years.
