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