The Origin of Betta Fish

Some information able to help you and that it will be beneficial for your Betta Fish care needs.

There are seems to be basic color genes either present or missing in the Betta Fish. The Base color is yellow, which is followed by black, red and then blue. There are also sub colors. The blue gene, for example, can be represented by royal blue, metallic blue, or bluish green. The beautiful royal blue is a mixture of the other blues.

If you spend time with Betta Fish experts, you will hear terms like "Veil Tail," "Delta Tail," "Crown Tail," "Plakat" and "Half Moon". Hearing all of this you might become confused, because you didn't know that there are so many of Betta species before. So this is a quick introduction to some of various lines of the Betta Splendens. Actually, the basic difference among the types of Bettas has to do with their tail.

Veil Tail - About 80% of Betta Fishs sold in pet stores are typically VT males. Veil Tail's are characterized by the bottom fin rays being a bit longer than the top rays. What are Rays? Rays are the little "spines" you see in the fins. With the fins flared out, VT Betta Fish look a bit rectangular or even diamond shaped. Most breeders and Betta care show enthusiasts frown on the VT Betta as an inferior breed.

Round Tail - The tail is round in appearance. The circular shape originates from the middle ray of the tail being the longest, with the remaining rays being progressively shorter away from the middle.

Delta Tail - The tail has a triangular shape, which emanates from the outermost rays on the tail being equal in length as the middle ray. In Betta Fish circles the widest tailed of the delta tails are the most desired.

Half Moon - A Delta Tail's tail can be so wide that it seems to form a half circle, or half moon shape. At this point it becomes known as the Half Moon Betta Fish. Half Moons Betta Fish are popular among hard-core Betta enthusiasts.

Double Tails - These cute little fish have their tail divide into two halves. Double Tails are genetic rarities that you probably will never find at a pet store.

Crown Tails - With this Betta the rays of the tail actually extend well past the webbing, this gives the tail a spiky appearance. The Crown Tails are the most common among the single rayed.

I hope that this small information able to help you and that it will be beneficial for your Betta Fish care needs.
