The Different Betta Fish Tail Types


The veiltail is by far the most common tail type for betta fish. To recognise it look for a long, flowing, downwards swooping tail.


Crowntail - betta fish tail types
Crowntail betta fish are a very popular choice. Named because of the spikey appearance of the fins – just like that on the top of a crown.

You will be able to recognize a crowntail due to the extended length of the fin’s rays and the small amount of webbing. If the webbing reaches further than 2/3 up the tail’s ray it is not a crowntail. Most breeders aim for the webbing to reach only half way.


Combtail - betta fish tail types
Combtail betta fish are similar to crowntails in that the tail’s rays are longer than the webbing. However combtails use this feature more subtly. The difference between the fin’s ray and the webbing is not so large.

Double Tail

A double tail betta will be recognize due to possessing two distinct tails which are separated to the base. Double tail betta fish also tend to have a larger dorsal fin.


Spade Tail - betta fish tail types
Named because of the very clear spade like appearance of the caudal fin. The tail has a wide base which then narrows smoothly to a point.


halfmoon - betta fish tail types
Halfmoon bettas are perhaps the most wanted type of betta fish. The halfmoon tail is large and when flared the caudal fin will fan a 180 degrees which causes the tail to create a half circle – and that is where the name comes from.


Over Halfmoon - Betta fish tail types
Over-Halfmoon betta fish have similar fins to halfmoon bettas. The difference is that when flared the caudal fin will fan over 180 degrees creating a shape that is larger than half a circle.


Delta Tail - Betta Fish Tail Types
A delta tail starts narrow towards the body of the betta fish and widens towards the tip giving it a triangular shape.

The delta tail type is similar to a halfmoon fin however the tail does not reach 180 degrees

The difference between this tail type and the veiltail is that if you were to draw a line horizontally across the centre of a betta fish there would be an even amount of tail above and below the line (The veiltail would have most of the tail below the line).

Super Delta

Super delta tail - betta fish tail types
The super delta tail type is very similar to the delta tail type however when it is flared it extends further. A super delta tail will flare between 120 to 160 degrees – it does not reach the 180 degrees of a halfmoon tail.

Half Sun

Sun tail - betta fish tail types
The Half Sun tail type is a combination of the crowntail and halfmoon. This results in a large tail with a spread of 180 degrees plus with slight crowning between the fins rays and webbing. The Half Sun is a very rare fin type.


Rose tail betta fish
The rosetail is a beautiful variation of the halfmoon tail type. The appearance differs from halfmoon tails due to excessive branching on the rays of the fins which causes overlapping on the fins giving a rose like aesthetic. Adding this betta to a dorm room will surely add to the interior.


Feather tail betta fish - betta fish tail types
The feathertail is very similar to the rosetail however there is even more excessive branching of the fin rays giving an extra ruffled appearance.

Plakat / Short Fin

Generally speaking the term Plakat betta is used to describe a short finned betta fish. The tail is short and round (sometimes going to a point) on the traditional Plakat.

Dumbo Ear / Elephant Ear

Ok, not quite a “tail type” however the dumbo ear or elephant ear betta fish has a fantastic aesthetic due to its fins. Dumbo ear bettas have extra-large pectoral fins which resulting in these fins looking like elephant ears. These fins can be a matching color to the betta’s body or contrasting.
