Betta Fish Facts

Before buying a betta, here are some things you should know.

The Homeland

Bettas were originally discovered in Siam, now known as Cambodia. This is where the name Siamese fighting fish came from. They are native to Thailand, Vietnam, China, and similar areas. Today, you can find them in most pet stores and even some department stores with a live fish department.

Mood Swings

Bettas are well known as fighting fish. They can get along with certain other fish breeds such as tetras, but cannot handle being too near another male. Females are less territorial than males. Males become agitated and fluff their fins as much as possible to try to intimidate other males. This is just a small part of a betta's personality. Just like with a person, every betta has their own unique personality.

Health can also affect a betta's mood. Normally, a betta is fairly active and swims very gracefully. When a betta is sick or unhappy, they will swim much slower and tend to just "lay" around on whatever rocks or pebbles are at the bottom of the tank. Dirty water, lack of food, or too much food may be the cause of their lack luster attitude. Healthy, happy females will normally have vertical stripes. Look for these stripes before buying a female betta, especially if she seems depressed.

Distinctive Features

Bettas are well known for their vibrant colors. Normally colors include various shades of red, blue, purple, and even white. Males have more vivid coloring than females. The main difference between male and female bettas is the size of their fins. Females have much shorter fins than males. Bettas can grow up to three inches in length. This makes them ideal for smaller tanks.

Preferences

Bettas prefer warm water. Keep the temperature between 70 and 80 degrees. They can live in cooler water, but try to keep it as close to 70 as possible. Bettas also need room to breathe. Since they breathe from the surface of the water, make certain your betta has some airspace at the top of the tank. In their native environment, bettas prefer live food, but flakes and pellets make a wonderful meal for them as well.

Bettas are a great pet for any marine lover. They are small, easy to care for, and fun to watch. They will typically live from two to three years. Large based vases and aquariums are perfect homes for bettas. With just a few supplies, you could own your very own betta today.
