Betta Fish Facts

There are some betta fish facts which may surprise you. Betta fish are very unique as compared with other fish in the world. Since the Bettas have an upturned mouth, they can feed from the surface of the water. In the wild they eat crickets, water spiders, flies, and other types of insect which land on the surface of the water. This gives them an advantage by allowing them to have a wider range of foods than other fish.

Betta Fish Food

Fish who have a larger selection of food tend to live longer, heal from any damage that may have ensued from fighting, and they have brighter coloring than other fish. Another Betta Fish fact is that in captivity Bettas which are fed a wide range of foods such as blood worms, broccoli, carrots, fish meal, soybeans, and such are more colorful than those which are only fed betta fish food.

Betta Fish Biology

A very unique Betta Fish Fact is that Bettas have an exceptional way of taking in oxygen other than by using their gills. They have a labyrinth organ located in their head which allows them to breathe in oxygen right out of the atmosphere. By being able to do this they can blow bubbles from their mouth which allows them to create a bubble nest needed for breeding.

Breeding Betta Fish

When it comes to reproduction and nests, another Betta Fish fact is that the male will chase the female Betta away once she has laid all of her eggs. The male does this to ensure that the newly released eggs do not get eaten by the female. The male keeps a watchful eye on the bubble nest and repairs it as needed until the eggs hatch. This usually takes about 3–4 days. Once they hatch they become what is called fry and are now free swimming. The male Betta will constantly try to keep the fry close to the bubble nest until their gills are fully developed. A healthy Betta Fish will live about 2–5 years; however it is rare for one to live past 3 years.

Betta Types

Betta Fish can have very different styles of tails. The Veiltail in a non–symmetrical tail, it has only two rays. The Crowntail is extended with spiny rays or fringetail. The Combtail is a shorter, less extended version of the Veiltail. Some have a Half–moon tail which forms almost a complete circle at 180 degrees. The Double–tail is what it says; it looks like two tail fins. The Delta tail has sharp edges and a span that is a little less than the Half–moon.

Betta Fish Behavior

Another Betta Fish Fact about other species and Betta fish is this – Bettas are naturally aggressive and placing them in an aquarium with other fish is just calling for a disaster. However, this fact isn’t true of all Bettas and other species. Some Bettas have a much higher level of aggression that others, but this isn’t something you can determine when you purchase one from your local pet store. It’s trial and error, sometimes you get lucky and your Betta has a low level of aggressiveness and can happily live among other community fish.

Bettas tend to bully and attack fish smaller then them as well as fish that have long flowing tails such as some tetras and guppies. Slower swimming fish are also an easy target for Bettas. Mollies are not a good choice for tank mates because they will bite the fins of the Betta and eventually will eat him if he is damaged too much. But like every creature on earth, each has their own behavior and some Bettas can live happily in the same aquarium with other fish, even those which are known to be bullied by them.
