The rays are extended to varying degrees on all fins giving the fish a "spikey" appearance.

They have the typical droop of the Veil tail but combined with some extended rays on all fins to varying degrees.

These are very similar to HM's but have less than a 180 spread when flared.

It is a genetic trait that causes the caudal fin to grow into two lobes rather than one.

This is a cross between a double tail and a veil tail.

Although it is an extension of the rosetail effect, the feathertail has much more than a ruffled appearance, the excessive branching actually gives it the look of feathers, with a kind of zigzag effect edge.

It is characterized 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.

Where the tail has a 180 degree spread when flared, but tail length is short.

It has the spread of a Halfmoon with the slight crowning of a Crowntail. The halfsuns have the tips of the rays protruding beyond the web, but not enough to be a crowntail or combtail.

This is the extreme end of the Halfmoon where the spread when flared is over 180 degrees.

The Plakat is a short-tailed Betta

A Rosetail is an extreme Halfmoon with excessive branching of the rays giving the tail a "ruffled" edge. If there is a huge amount of branching it can be referred to as a "Feathertail".

The fin shape is round, rather than the straight edges of a Delta, but fuller and longer than that of a Plakat.

This type 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.

These are nearly an HM but not quite, Deltas are far less than an HM.
