Betta Bits: Betta Tail Types and Patterns

The different breeds of Bettas are often distinguished by their tail types and patterns. Here are some of the most common Betta tail types:

Plakat (Short-tailed Betta)

Plakat Tail







This group closely resembles the wild Bettas. Because of their short fins, they are often mistaken for female Bettas. Although both male and female Bettas of this variety have shorter fins compared to other Betta groups, males can be distinguished by their longer ventral fins, more pointed anal fin, and slightly different body shape.

Veil Tail

Veil Tail







This is the most common breed of Betta fish. The name of the breed comes from the movement of the tail—tails arch up and float down like a veil. They have long-smooth-edged, flowing fins, with somewhat rectangular tails that angle downward. For breeders, veil tail bettas are considered undesirable particularly when breeding for show-quality form.


Crown Tail








Also called, Half Sun, the Combtain is a result of crossing a Crowntail and a Veil Tail. The fin rays extend beyond the end of the fins’ webbing. The extension of the rays is shorter than that of the Crowntail.


Double Tail

Double Tail







This breed of Betta has its caudal tail split into two equal lobes, earning the name double tail. The tail almost creates a full circle when flaring. Double Tails have two caudal peduncles, with shorter bodies compared to other tail types. This makes them more predisposed to Swim Bladder problems.  With their lovely broad dorsals, they are often crossed with other strains.


Spade Tail






Spade Tail Bettas are not as popular as they were in the early 1990s. Its name is derived from the wide base of its caudal fin that narrows to a delicate point, like a spade.



Delta Tail







Delta Tail bettas are often mistakenly described as single-tailed non-Halfmoon (HM) betta. The true Delta tail has straight caudal edges like a Halfmoon or SDT, however the similarity ends there. The Delta tail’s caudal edges extend outwards from the betta’s back and don’t arch straight up. Also, their tail fins have less than a 180-degree spread when flaring.

Super Delta Tail

Super Delta Tail







Also known as SDT or HMx, the Super Delta Tail possesses a fin type that is midway between Delta and Halfmoon. When flared, the fish’s tail fin spreads wider than a Delta Tail, but still not reaching 180-degrees.



Half Moon Tail








Halfmoons can easily be distinguished from Delta Tails by the 180-degree spread of its tail when the fish flares.



Half Sun Taill







The Halfsun is a cross between the Halfmoon Betta and the Crowntail. It is characterized by the slight extension of the rays beyond the webbing at the fins’ edge.



Rose Tail








The Rosetail is another variation of the Halfmoon Betta. The group is characterized by rays that branched excessively at the tips, creating an excess of fin that folds over itself, giving the fin a ruffled appearance, like rose petals.


Round Tail







These are single-tailed bettas that possess rounded edges. Round Tail bettas are often confused with delta tail, super delta tail, and halfmoons.
