Facts About Betta Fish
Here are some top betta fish facts that will help you understand one of the most popular exotic pets. This information is not only very interesting but should help you keep your betta healthy and happy for many years to come.
Origin Of bettas And Other Names
The betta fish is also commonly referred to as Siamese fighting fish or the Beta Fighting Fish. It finds it's origins in Thailand and is a part of the "Osphronemidae" family of fish. While most betta's you see today are bred locally due to the high cost of acquiring a wild specimen they can still grow quite large with the average size being 2.5 to 3 inches in length.
What Do Betta's Eat?
Betta's are known to be picky eaters. In the wild, they typically will eat insect larvae and other small organisms. For domestic pets, the usual food is either betta flakes or pellets which you can get in most pet stores. The proper feeding should be two to three pellets/flakes twice a day. One-day weekly fasting helps maintain proper health and clean out their digestive systems.
They are also known to enjoy brine shrimp, mosquito larvae, and bloodworms. As with all feeding be sure to remove any uneaten food. This will ensure the tank environment remains clean.
Best Betta Fish Tank Environments.
The optimum tank temperature should be between 75-85 Degrees Fahrenheit. Special care should be taken to monitor ammonia levels on new tanks. This can make your betta sick or even worse can be fatal. Be sure to wash your tank properly and change the water on a regular basis to maximize the lifespan of your betta.
The average lifespan of a typical domestic betta fish is between two and four years. Those kept in a well-maintained aquarium reaching more than a six-year lifespan.
Here's a little-known betta fish fact that might amaze you! Bettas have a unique organ (respiratory) that will allow them to breathe air from the surface. As a result, they must have access to the surface of the water so that they can breathe directly from the top. It is important to your betta's health to allow good ventilation from the outside.

How to Have Happy Healthy Betta Fish.
One of the most important things about betta health is to keep a clean and properly maintained the tank. The average life span of a betta fish is about two to three years. However, with the correct environment, a betta can live as long as 6 years. Here are some of the most common health problems that can affect your betta fish.
Betta Fish Stress
Stress is a common problem with many different types of pet fish, and the betta is no different. The symptoms are usually common and can be diagnosed rather easily. Some of the most frequent symptoms are open sores (usually white or red in color) spotted skin and noticeable difficulty in breathing. They may also remain still or lie on the bottom of the tank for extended periods of time.
Usually water quality or other environmental conditions such as ammonia poisoning or recent changes to their habitat such as a new tank element can be the cause of their stress. Transfering them to a temporary container when you clean their tanks may also be a contributing factor.
Improper Tank Size.
Usually betta fish come in a small plastic cup when you purchase them from the pet store. In the wild, they live in rice paddies and ponds that are typically shallow still water, with lots of swimming room. A one-gallon tank is a minimum size you should have for them to live in. Any smaller can cause stress or create poor water quality which can lead to diseases and other health problems.
No Access To the Surface Air
One of the unique things about a betta fish is an organ called the “labyrinth“ which allows them to breathe air from the atmosphere. Due to this organ betta fish rely on and need access to surface air to remain healthy. As a result, it is important to have a large surface area. This should include good ventilation to ensure your betta`s optimum health.
Incorrect Water Temperature.
Betta fish should be provided with a clean environment. Water temperature should be between 70 and 80 degrees, which mimics the conditions found in the wild. An electric tank heater that maintains a constant temperature is highly recommended. This is to ensure the water is not too cold which can result in poor health or loss of color. Hopefully this guide to finding the best betta tank will have helped you find the right home for your betta fish.
