Bettas are available in a rainbow of colors, all apearing in different combinations and patterns, as well as being displayed on many different types of finnage. We will introduce to you here some of the varieties of bettas that are available.
This fin variety most closely resembles wild betta splendens, as long tails and the subsequent tail types were all selectively bred by human intervention. These fish are often mistaken for female bettas, who generally have shorter fins, but this is an entirely different variety of betta. Males can be distinguished by females by their longer ventral fins, more pointed/angled anal fin, and slightly different body shape.
The most common fin/tail type, these fish have long, smooth-edged, flowing fins and a somewhat rectaungular tail that angles downward, like a veil.
This fin/tail type involves fins whose rays extend well beyond the webbing of the fin itself, giving the fish a spiky appearance. The standard for showing bettas states that for a fish to be classified as a Crowntail, the extended rays must account for at least 1/3 (33%) of the fin length, with webbing existing for no more than 2/3 (66%) of the fin's length.
A more subdued version of the Crowntail above, simply defined by the fin rays extending beyond the end of the webbing in the fins. The extension of the rays is much less than that seen in a Crowntail.
A fin type in which the caudal (tail) fin is split into two lobes instead of one. This is a genetic trait, and the same genetics that cause this double-tail cause the dorsal and anal fins to be very broad and the body to be shorter, which predisposes these fish to swimbladder problems.
The Spadetail fin variety is characterized by a tail fin that initially flares upward and downward from the caudal peduncle, like the Delta tail variety, but the fin then tapers down to a point, appearing like the shape of a spade.
A fin type in which the caudal (tail) fin flares out from the caudal peduncle to the fin tips, forming the shape of a fan, or a pie wedge. These fish are similar to the Halfmoon variety, but are distinguished in that their tail fins have less than a 180 degree spread when the fish flares.
Super delta tails are an intermediate fin type between delta and halfmoon. This fish's tail fin will have a wider spread than a delta tail when flared, but still not a full 180 degrees.
This fin/tail type is similar to the delta and super delta tails described above, but when the fish flares, the tail has a full 180 degree spread, appearing in the shape of a "D" or half moon, hence the name.
The Over-Halfmoon tail type is a further expansion on the Halfmoon variety, and is the same except that the tail fin has a greater than 180 degree spread when the fish flares.
A very rare fin type, the Halfsun betta has the full fins and 180 degree tail spread of a Halfmoon type, but has been crossed with a crowntail to produce a slight extension of the rays beyond the webbing at the edge of the fins.
Another variation of the Halfmoon tail type, this fin variety includes rays that have branched excessively at their ends, creating so much extra fin that it folds over itself, like the petals of a rose, giving the fin a ruffled appearance.
Butterfly refers to a coloring pattern in bettas where the outer part of all fins is either white or clear, blending part way up the fin into another color or color pattern.
Piebald describes the color variety of a fish with a dark colored body and white head.
Cambodian describes a betta color variety in which the fish has an entirely white or pinkish body, and solid colored fins (usually red, which was the original Cambodian variety, but other colors are acceptable)
A color and scale variety, Dragon describes fish bred for thick, metallic scaling that resembles armor.
