Its spiky tail and fins give the crowntail Betta its royal look. The tail has a teardrop shape with webbing between the rays that’s unmistakable to this breed.
Doubletail
As its name suggests, doubletail bettas have two distinct tails, each shaped like a half moon. This sets them apart from similar-looking bettas, which have only single, split tails.
Halfmoon
One of the prettiest betta breeds, the halfmoon Betta has a 180-degree, fan-like tail that resembles a “D” when fully flared. This long-finned Betta also has unusual coloring.
Plakat
The ancestors of all betta fish, plakat bettas have shorter tails with round or spade shapes. These strong, aggressive betta fish are less prone to injury and disease.
Round Tail / Fan Tail
Sometimes mistaken for other bettas, the round tail (or fan tail Betta) has a single tail that’s round and full.
Rosetail / Feathertail
A kind of halfmoon Betta, the rosetail (or feathertail Betta) also sports a fan-like tail, but has excessive branching and overlapping in its fin rays that resembles the ruffled appearance of a rose.
