Rosetail & Feathertail

Rosetail and Feathertail is an extreme Halfmoon with excessive branching of the rays giving the tail a "ruffled" edge. It has so much finnage that it overlaps like a rose. These fish are hard to breed on as the excessive mutations that cause the branching can lead to other mutations such as poor scales and short ventral fins. Can be seen in longfin and shortfin.

Halfmoon Tail Betta

The Half Moon is a very desirable tail type. It is characterised by having the full 180 degree spread when flared, forming a "D" shape with straight edging. Dorsal and anal fins are also dramatically larger than those on other fin types. HMs are prone to tail-biting and fin damage, their tails are large and unnatural and HMs often feel hampered down by their fins. This also means they're one of the hardest tail types to breed as the males find it hard to successfully wrap the females.

Modern Plakat ( Halfmoon Plakat )

 Basically shortfinned version of halfmoon, super delta, doubletail, crowntail. 4+ ray branching , 180 or better tail span with sharp edges , wider dorsal , and symmetrical  form. Shortfin trait is recessive to the longfin mutation.

Plakat Betta

The Plakat, or Plakad, is a short-tailed Betta, and is the most closely related to wild Betta splendens or traditional fighting Bettas. Plakats can often be mistaken for female Bettas to the untrained eye, however, males will display elongated ventral fins, a rounded caudal fin and a sharply pointed anal fin. There are 3 sub-categories related to this tail type. There is the traditional Plakat where the tail is rounded, sometimes with a point. Now, due to selective breeding and crossing, there is also the Half Moon Plakat where the tail has a 180 degree spread when flared and the Crown Tail Plakat has the tail is either rounded or with a 180 degree spread and with elongated rays giving it a "spiky" appearance.

Spade Tails

The Spade Tail has an equal spread on either side of the fin, similar to a Round Tail, but with tail finishing in a  point rather than a rounded edge. The bottom fins are straighter and pointier. Caudal has a wide base that narrows to a delicate point

Round Tails

The Round Tail can be compared to a Plakat with a large tail, and mistaken for a Delta. The fin shape is round, rather than the straight edges of a Delta, but fuller and longer than that of a Plakat. This can also be referred to as a "Single Tail".

Super Delta Tails

Super Deltas are very similar to Halfmoons but have less than a 180 spread when flared. They are nearly a Halfmoon but not quite. Super Deltas are differentiated from Veil Tail by the fact that if you drew a line from the nose to the tip of the caudal fin on a Super Delta there would be an equal amount of fin on either side of the line, whereas on a Veil Tail there would be little tail at the top, and the majority below.
