The Veil Tail
The most widely-available longfin form in bettas is inarguably the Veil Tail betta (or VT). This is the natural form the fins take when they are artificially lengthened from the wild shortfin form with selective breeding. |
The Spade Tail
This tail form is pretty basic; the caudal has a wide base that narrows to a delicate point, like a spade.
|
The Doubletail
The Doubletail is a cultivated mutation that gives the fish a dorsal fin equal in length to the anal fin, and two distinct caudal lobes.
|
The Roundtail
The term "roundtail" is most usually used to describe a single tailed betta with rounded caudal edges.
|
The Delta Tail
Delta tail has straight caudal edges like a HM or SDT, but they extend outwards from the back of the fish and don't arch straight up into HM.
|
The Super Delta Tail
This is basically an enhanced version of the standard Delta Tail, and some are just shy of being full HM.
|
The Half Moon
Specifically, a halfmoon betta must have a caudal where both ends are exactly 180 degrees apart or more, spreading towards the front. Caudal edges have to be straight or curving outwards, and not bending inwards. |
The Rosetail
The quest for the perfect halfmoon by selectively breeding for branching and straight caudal edges has given rise to a new development in the Betta splendens tailforms - the Rosetail.
|
The Plakat
The Plakat (from the Thai word 'pla kad', meaning 'biting fish') is just the shortfinned version of the common Betta splendens.
|
The Crowntail
The webbing between the fin rays of these bettas is reduced, producing the appearance of spikes or prongs, hence the name "Crown Tail". |
