The species of crowntail has only been around for about 25 years. This fighting fish’s remarkable tail inspired its name. The crowntail reaches a maximum length of two and a half inches on average, though some males can reach three inches.

Their fins have rays that are sharp and extended, like a crown. They achieve this look because the fin rays of the tail fin, dorsal and anal fin are lengthy, but the webbing between them is reduced by over a third. They come in various colors and are favored for their striking appearance.

Long-finned species, such as the crown tail, are stunning, but they also have a tendency to nip their tails, and their fin rays curl in low-quality water. Even though they can swim better than some other species, they still prefer calm waters.

Their flowing tails account for the majority of their length. Males’ tail fins can grow up to three times their body size. The fish resembles a crown due to the webbing that runs between its rays on its tail.

2. Halfmoon

A stunning breed with a tail that resembles a 180-degree fan is the Halfmoon. When the tail is fully extended, it resembles the letter “D.” Even though the Halfmoon is a relatively young species.

This fish has only gained popularity since the 19th century, when fish fighting became more common. The halfmoon can be deep blue, vivid red, purple, or orange, with an average length of three inches.

The fins of this breed are amazing; when completely flared, they overlap to give the impression that they are one continuous fin, extending from the dorsal fin to the pelvic fins behind the skull. It is a fantastic option to bring vitality to any aquarium because of its stunning fins and distinctive coloring.

3. Delta or Super Delta

The tails of the delta and super delta bettas resemble the Greek letter “D” or “delta.” As the fish travels, its tail and fins flare, producing a stunning image as it moves through the water. 

Like the Halfmoon, the delta and super delta tail fins have straight edges. But they don’t get as big as the Halfmoon does. The tails of super deltas flare out almost but not quite, to 180 degrees. They could extend in a 120–160 degree range. That falls just short of the fishtails on a half-moon.

4. Dumbo Ear

No, unlike Dumbo the elephant, the dumbo-ear-fighting fish does not have large ears. Large pectoral fins that protrude from either side of the fish’s face are what look like ears. These fins resemble elephant ears quite a bit.

Although the other fins in this species vary in size and shape, having such large fins might make swimming challenging. These betta fish should be kept in extremely quiet water, just like the rose tails, to avoid having to struggle against the current.

Aquarium owners should be aware that, despite its beauty, the dumbo ear betta is among the more aggressive species of fighter fish.

5. Combtail or Half Sun

The Halfmoon and crowntail species have crossed to produce the stunning half-sun fighter fish. The outcome is a stunning yet vicious species with a 180-degree tail spread, like a half-moon combined with the crown tail’s webbing.

Combtails make more subtle use of this feature, though. It’s not very apparent how the fin’s ray and webbing differ. A caudal fin that resembles a fan is a common feature of combtail Betta fish. Its widespreadness typically doesn’t extend past 180 degrees.

6. Plakat or Shortfin

The plakat betta fish are more agile than other fish because of their short, round tail and rounded dorsal fins, which enhances their fighting abilities. Plakat betta fish are also less prone to develop fin problems from tearing.

7. Double Tail
