Most Frequently Asked Questions About Bettas
First, learn more about bettas themselves. Here are answers to the general questions most budding betta enthusiasts ask.
How big can bettas grow?
On average, male bettas grow to about two to three inches long, including their fins. Females tend to be smaller with shorter finnage. In recent years "king" bettas have come on the market that have heavier bodies and range three to four inches long.
What is an average lifespan for betta fish?
With the right environment and a good diet, betta fish generally live two to three years, but some have been known to live as long as five years.
What should bettas be fed?
Betta fish that live in the wild eat live food, mostly bugs. In captivity, bettas can eat pellets and flake food formulated for their species, and they should also receive fresh or frozen brine shrimp, as well as freeze-dried bloodworms and daphnia. Their stomachs are only as big as their eyes, so feed small amounts twice times a day, and rotate foods to offer complete nutrition.
How can you tell if a betta fish is sick?
- Fin damage/deterioration
- Loss of appetite
- White fungus attached to the fins and scales
Betta Tank FAQ
Now learn how to select and maintain the right environment for your betta. This information will help your fish enjoy a higher quality of life.
Which size tank is most appropriate for betta fish?
While betta fish can live in those tiny bowls in a store, this is not an ideal situation. It works because they're alone and because they are able to breathe the surface air. However, water conditions can deteriorate quickly in such a small container, so each fish should live in a tank that holds at least one gallon of water, and preferably two to five gallons. This will give the fish plenty of room to move around in, and the overall environment will be more stable.
Do betta fish need special equipment in their tank?
Bettas have a gill system just like other fish, but they have an additional organ called a labyrinth that also enables them to breathe the oxygen in the air above the surface of the water. This is why they can live quite well in large bowls without air pumps and filtration systems, but it's still better if you can provide a fully working tank because this will help maintain better water quality between tank cleanings. Bettas like warm water, so a heater and thermometer are needed to keep the water at the right temperature. Caves and plants are also good additions to the tank so your betta has a place to occasionally hide, relax and even take a nap.
What should the water pH and temperature range be?
According to the International Betta Club, the ideal temperature range for bettas is 76 to 78 degrees Fahrenheit. These fish are a little hardier than some tropical fish, and they do well in a pH range between 6.5 and 7.0. Ammonia and nitrite levels should be kept at 0, and the nitrates under 20. You can buy a water testing kit that will help you determine the levels.
How many betta fish can live in one tank?
Male bettas are quite aggressive towards other bettas, especially other males, so you should only keep one male in each tank. Females can also be kept separately, but it is possible to keep three to five females together in a 10-gallon sorority tank as long as there are enough plants to offer hiding places and territorial divisions.
Which other types of fish can I keep with my betta?
Bettas can be kept with non-aggressive tropical fish of similar size that require the same temperature and pH ranges. Some examples include platies, mollies and swordtails. Bettas often view guppies as smaller male bettas, so avoid those as well as gouramis since both will provoke a betta's territorial instincts. The best procedure is to only introduce your betta to one new species at a time and see how well he reacts.
How often should the tank be cleaned?
Betta fish need clean water, otherwise they become stressed and susceptible to disease. One-gallon bowls and filtered tanks should get weekly cleanings and water changes to remove harmful toxins. However, not all of the water should be changed at the same time. According to the vets at PetEducation.com, the old tank water contains beneficial bacteria that convert ammonia to nitrites which are then converted to nitrates that can be removed with partial water changes. Plan to remove and replace 25 percent of the old water with fresh, dechlorinated water. The fish droppings can be pulled out of the tank with a turkey baster.
