This is a draft for a rewrite of Siamese fighting fish#Tail shapes

Tail shapes[edit]

A black devil Crowntail male
A metallic, double-tail male Betta

In the wild, all bettas have short fins, and the long fin gene is a mutation that is genetically dominant.[1] This dominant trait has allowed many different tail, or caudal fin, shapes to be developed and established through selective breeding.

Veiltail[edit]

This is the most common tail shape found in pet stores, and are available in the largest variety of colors due to being genetic mutts.[2] Veiltails droop behind the fish and are asymmetrical because their rays are curved, not straight like the other tail shapes. The veil genes are extremely dominant,[3] and mostly veiltails will be produced from a cross with other types. Veiltails are generally not a desired type by show breeders because they are no longer allowed to compete.[2]

Delta Tail[edit]

A symmetrical tail that is much broader at the edges than the base, similar to the capital Greek letter delta (a triangle).

Fan Tail[edit]

a rounded delta tail

Halfmoon[edit]

large tail fin that forms a 180-degree, or larger, half circle

Comb Tail[edit]

less extended version of the crown tail

Crowntail[edit]

highly frilled, extended spiny rays

Plakat (Short-tail)[edit]

Short-finned fighting style (sometimes called "plakat")

Double Tail[edit]

the tail fin is split into two lobes and the dorsal fin is significantly elongated)
