Betta fish, also known as Siamese fighting fish, are a popular choice among aquarium enthusiasts due to their vibrant colors and striking fins. Although they prefer solitude, bettas are quite friendly and can become bored or unwell if not given enough attention. Betta fish can and deserve to be companions rather than just beautiful decorations in a tank. By providing proper care and regular interaction, you can develop a close bond with your betta.
Steps
Selecting and Caring for Betta Fish

Choose a healthy betta fish. With proper care, betta fish typically live 2-4 years, and some can even reach 10 years. Selecting a healthy fish and caring for it correctly is the best way to build a lasting bond.
- Most bettas sold in pet stores are males, as they have brighter colors and larger fins. Whether you choose a male or female, look for a fish with vibrant colors (not dull), intact fins, and a healthy appearance.
- You might prefer an active and lively fish over a quiet one, but behaviors in pet stores may not accurately reflect a betta's true personality. They might be tired after a day of people tapping on their tanks.

Prepare a suitable home for your fish. You might have seen a betta fish swimming in a glass bowl or even a drinking cup in someone's office or home. Because bettas are solitary creatures, many assume they don't need or enjoy living in larger tanks with ample water.
- You may have heard that bettas prefer small spaces, as their natural habitat includes shallow puddles left by buffalo in their native Southeast Asia. While bettas are sometimes found in such confined areas, this only highlights their adaptability during dry seasons, not their preferred living conditions.
- In reality, bettas enjoy having space to explore, so you should choose a tank that holds at least 12 liters of water, ideally up to 40 liters. This might seem excessive for a small fish, but it ensures your betta has the best chance to live a healthy and happy life.
- The tank should be heated to between 24 and 27 degrees Celsius and equipped with a gentle filter that doesn't create strong currents (bettas prefer calm water). Keep the water clean and change it regularly.

Understand that bettas prefer solitude. While some bettas can coexist with others, many, especially males, become stressed, agitated, and aggressive when their space is invaded.
- Despite being called 'fighting fish,' male bettas are more about establishing dominance than causing harm. However, fights and injuries often occur when two or more male bettas share a tank. Therefore, it's best to assume male bettas should live alone.
- Female bettas also struggle to coexist peacefully, but they can live harmoniously in groups of around 10 (known as a 'sorority'). So, you can keep female bettas alone or in a group.

Feed your betta properly. A betta's diet is quite specific, consisting mainly of three types of food: betta pellets, bloodworms, and brine shrimp (often freeze-dried).
- Feed your betta twice a day, offering 3-4 pellets (crushed if the fish is small) or 6-7 bloodworms/brine shrimp per feeding. Bettas can overeat if given the chance, which is harmful to their health. They can also suffer from constipation (indicated by a swollen belly), which some say can be treated by feeding them a small piece of thawed, chopped pea.

Learn more about your fish's species. Bettas, also known as Siamese fighting fish, originate from Southeast Asia, and males are particularly aggressive toward each other.
- Bettas are incredibly resilient. They thrive in rice paddies in Southeast Asia and adapt well to fluctuating water levels.
- Bettas are among the few fish that can breathe oxygen from both air and water. As long as there's moisture, they can survive briefly without water. They can also live in small, brackish ponds (common during dry seasons) for extended periods.
Building a Bond with Your Betta

Place the tank in a high-activity area. While bettas are solitary, they can get bored easily and enjoy being in places with 'action' while still having their own territory.
- Position the tank in a busy area like the living room or near the kitchen. Bettas enjoy movement and activity, even if they aren’t directly involved.
- Occasionally move the tank to a different spot in the room to change the scenery. New surroundings will capture your betta’s attention and keep it entertained.

Name your fish and talk to it. Building a bond with a nameless creature is challenging, so choose a name that suits your little friend’s personality. If needed, search online for betta fish name ideas, similar to baby name lists.
- Bettas are sensitive to vibrations caused by sounds, such as human voices, and many believe they can eventually recognize your voice and their name. Try calling your betta’s name whenever you approach the tank to stimulate a response.
- At the very least, talking to your betta provides the interaction it craves and helps you build a connection. After all, who doesn’t want a friend who listens?

Create an engaging environment for your betta. Moving the tank, as mentioned earlier, is one way to change the scenery, but even observing your betta more often can provide something new for it to notice and eventually recognize you.
- Male bettas are known for 'flaring' at their reflection—a reaction to what they perceive as another betta. Whether flaring at a mirror is good (exciting) or bad (stressful) is debated. Note that some bettas may be shy or even scared of their reflection.
- Besides occasional mirror exposure (if desired), you can use a whiteboard marker to draw or cut sticky notes into shapes and stick them on the tank, or simply place new, visually appealing objects near the tank. Observe how your betta 'studies' and reacts to these new stimuli.

Play with your betta. While tapping on the tank is a natural instinct for many, avoid doing so, as the amplified sound can stress the fish. Instead, run your finger along the tank’s side and watch your betta’s reaction.
- Your betta might swim over to investigate your finger or even follow it as you move it along the glass. You might even get it to swim in loops following your finger.
- Bettas enjoy surfacing, so floating toys or objects can be a great way to entertain them. Ping pong balls are particularly fun—just make sure to clean them first.

Train your betta. Like most animals, including humans, the promise of rewards can be a powerful motivator for bettas. With patience and practice, you can teach your fish some fun tricks.
- Train your betta to eat from your hand by gradually moving your finger closer each day when dropping food into the water until it eats directly from your hand. It might even jump to grab the food.
- Use a lure to teach your betta to swim up or even jump through a hoop (which you can shape from soft wire). You can also train it to push a ping pong ball into a net.

Befriend your betta. The best way to build a bond with your betta is to treat it like a true companion. Spend time with it during happy moments, stressful times, or even when it’s feeling under the weather. Building a connection with any living creature requires effort, patience, openness, and care.
Warnings
- Always wash your hands thoroughly before putting them into the betta’s tank.
- Avoid shaking the tank, as this can stress your fish.
- Invest in a betta first-aid kit to be prepared for treating illnesses.
- Never house two male bettas together. Research before keeping multiple females, and avoid mixing males and females.
- Research thoroughly before adding any other animals to the tank, and ensure the tank is spacious enough for all inhabitants.
- If you don’t use water conditioner for tap water, your betta may fall ill and could die easily.
