5 Common Mistakes to Avoid as First-Time Betta Owners

Betta fish, also known as Siamese fighting fish, are popular pets due to their vibrant colors and easy maintenance. However, owning a betta fish requires more than just putting it in a bowl and feeding it once a day.

First-time betta owners often make mistakes that can harm their fish's health and well-being. In this article, we will discuss the top mistakes that first-time betta owners make and how to avoid them.

Mistake #1: Housing in a Small Bowl or Tank

Betta fish are often sold in small cups or bowls, leading many first-time owners to believe that they can keep their fish in a small tank or bowl. However, bettas need at least 5 gallons of water to thrive. 

A small bowl or tank can quickly become polluted, leading to poor water quality and health issues for the fish. Additionally, bettas are active fish that need room to swim and explore. A small bowl or tank can lead to boredom and stress.

Solution: Invest in a Properly Sized Tank

Invest in a 5-gallon tank or larger with a filter and heater. This will provide your betta with a healthy environment and plenty of room to swim. Make sure to cycle the tank before adding your fish to establish healthy bacteria that will help keep the water clean.

Mistake #2: Overfeeding

Many first-time betta owners overfeed their fish, leading to obesity and health issues. Bettas only need to be fed once or twice a day, and each feeding should consist of only a few pellets.

Solution: Follow a Feeding Schedule

Create a feeding schedule and stick to it. Feed your betta once or twice a day, and only offer a few pellets at each feeding. You can also supplement their diet with live or frozen foods, such as brine shrimp or bloodworms.

Mistake #3: Not Providing a Proper Diet

Betta fish are carnivorous and require a high-protein diet. Many first-time betta owners feed their fish a diet of only pellets, which can lead to health issues.

Solution: Offer a Varied Diet

Offer a varied diet that includes high-quality pellets, live or frozen foods, and occasional treats like freeze-dried krill or shrimp. This will ensure that your betta is getting all of the nutrients they need to thrive.

Mistake #4: Not Maintaining Water Quality

Poor water quality can quickly lead to health issues for betta fish. Many first-time owners don't realize the importance of regular water changes and tank maintenance.

Solution: Regular Water Changes and Tank Maintenance

Test the water regularly and perform partial water changes as needed. Aim to change 25-50% of the water every week. Also, clean the tank and filter regularly to prevent the buildup of waste and debris.

Mistake #5: Overstocking the Tank

First-time betta owners may be tempted to add other fish or aquatic creatures to their betta's tank. However, bettas are solitary fish that prefer to live alone.

Solution: Keep Your Betta Alone

Keep your betta's tank free of other fish or creatures. This will reduce stress and aggression, and ensure that your betta has enough space and resources to thrive.


Owning a betta fish can be a rewarding experience, but it's important to avoid common mistakes that can harm your fish's health and well-being. By investing in a properly sized tank, following a feeding schedule, offering a varied diet, maintaining water quality, and keeping your betta alone, you can ensure that your fish will live a long and healthy life.
