How to Properly Care for Betta Fish
Bettas are gorgeous fish, with long fins and stunning colors. Also known as Siamese fighting fish, they need the right aquarium setup to thrive, and when cared for properly, they can reach an average of 3 inches in length and live three years or longer.
Once you have a betta, you’ll quickly realize why they’re so popular. In addition to being fun to watch, they’re smart fish who will recognize you and swim over to say hello if you approach their tank. You’ll also see them breathing air at the surface of the water and making bubble nests, so they’re fascinating and interesting pets for the whole family.
Ready to learn more about bettas and their needs? Here’s an overview of how to care for them and what you can expect as a betta owner.
It Starts with the Right Environment
With any fish, water quality is key to keeping them healthy and happy, and giving them the right amount of space is also important.
Tank Size, Filter, Heater, and Lighting
While you might’ve seen bettas in tiny cups at pet stores, they shouldn’t be forced to live in bowls, especially tiny ones, or planted vases. These fish should be able to swim freely, and should live in a filtered tank that ensures their water is clean.
Generally, experts recommend a 5-gallon tank for one betta, at a minimum, but consider if you’ll want to keep your betta with other fish, as that will help you determine the appropriate aquarium size to ensure they’ll all be comfortable and healthy.
A 10-gallon tank with a lid is a good size to start with for a betta, but you can certainly go larger if you’d like—you’ll absolutely love watching their graceful fins as they move through the water. Just be sure to purchase a filter that will work for the number of gallons in the tank you select.
In addition to a low-flow filtration system that doesn’t produce a strong current, install a heater in your tank to keep the water within a safe temperature range for your betta: 76-81° F (some experts recommend sticking with 78°F for bettas). Keep a thermometer in your tank to monitor the temperature.
Also invest in aquarium lighting so you can turn it on daily and give your betta the day/night cycle they’d naturally experience in the wild.
Tank Maintenance
After setting up your aquarium, maintain it to keep the water quality high. Perform partial water changes on a regular basis and remove debris and algae from throughout the tank.
When adding fresh water to the tank after a cleaning, treat it with a water conditioner and ensure its temperature matches the temperature of the water in the tank.
Use a water testing kit like the API Freshwater Master Test Kit to monitor aspects of the water quality, such as pH, ammonia, nitrate, and nitrite, and ensure they’re all within safe ranges for all of the fish in your tank, including your betta.
Tank Décor
Make your betta’s tank beautiful with décor of your choice. Line the bottom with gravel or sand, and add a variety of live and/or fake plants, rocks, hideouts and caves, driftwood, and other aquarium décor that’s safe for your pet and doesn’t have sharp edges.
Carefully Choose Tankmates
Because male bettas are aggressive toward other male bettas, they shouldn’t be housed together. Males can also attack females, so it isn’t a good idea to house them in the same tank. You can, however, keep multiple female bettas in the same aquarium.
When choosing tankmates for a male or female betta, stick with peaceful species who won’t be tempted to nip at their fins. And if you’re setting up a community tank with multiple fish species, avoid those with fancy fins and bright colors, as your betta may attack them, too. For example, peaceful tetras and rasboras are good choices, while tiger barbs and gouramis aren’t.
Provide all of your fish with plenty of room and hiding places so they can live in harmony. Just keep in mind that the more fish you keep, the bigger the tank needs to be. Also, don’t overload your tank with too many fish—use their adult sizes and the number of gallons in your tank as a guide.
Consult an expert if you aren’t sure about the number of fish you can keep in your tank or the types of fish you can house together with your betta.
Feed Them Right
Bettas are carnivores who are easy to feed, thanks to the many options made for them, including pellets, flakes, and live, frozen, and freeze-dried foods and treats. With the right diet, you can ensure their nutritional needs are met.
Avoid overfeeding your fish, as it can affect their health and water quality. A pinch of food that can be consumed in a couple minutes, once or twice a day, may be enough to keep your betta happy and well-nourished.
One example is Hikari Betta Bio-Gold. These floating pellets are optimally balanced and color-enhancing specifically for bettas.
Another example is the Omega One Betta Treat Bloodworms. These are tasty treats that are high in protein and provide vitamins and minerals for bettas.
Monitor Your Betta Fish Daily
After bringing your betta home and giving them time to acclimate to your aquarium, keep an eye on them daily to look for signs of illness, such as changes in behavior, appetite, or appearance. If your fish seems unwell, consult a fish expert or veterinarian who can provide guidance and possible treatment.
By providing your betta with a healthy, safe, and engaging environment, you can enjoy your beautiful fish’s company for years. So, learn as much as you can about this species and its unique needs before deciding if bettas are right for you.
