1. What is combtail betta?

A Combtail betta is a hybrid between a Crowntail and a non-Crowntail species, resulting in a fish with reduced tail webbing. Unlike the traditional Crowntail that requires at least a 30% reduction in membrane material for each major fin, Combotails typically have less than a 30% reduction in tail webbing. Since the reduction in fin membrane material is not sufficient to classify it as a purebred Crowntail, the betta is classified as a Combtail. This results in fins that are more rounded or slightly pointed but still remain wide and long enough to be noticed and appreciated.

In addition to their unique tailfin, Combtail Bettas have a variety of color combinations. They can range from solid shades to multicolored patterns. Some Combtail Bettas are also metallic in appearance, imitating the shimmering scales of other fish species.

Combtail Bettas are hardy and resilient, making them easy to care for at home. With proper maintenance and diet, they can live up to 3-5 years in captivity. As with any pet fish, owners should monitor water quality regularly to ensure the health of their Combtail Betta.

2. Distinguish Combtail from Halfsun tail

Both the combtail and halfsun fish are Crowntail crosses with none-crown tail. However, the combtail betta has a tail that spreads at less than 180 degrees. This gives the fish a distinct and unique appearance, with its tail resembling the top of a rooster's comb. The fins on the combtail betta are shorter in comparison to other Bettas and they have more pointed edges. This makes them appear sharper and thinner than their counterparts. 

On the other hand, halfsun bettas typically have tails that spread at 180 degrees, giving them an almost circular shape resembling a fan. Their fins are longer with rounded tips, giving them a softer look compared to combtails.

3. Distinguish Combtail from Crowntail

A Combtail betta can be identified by its unusually long fins with increased branching and webbing, giving it an overall "comb" like appearance.

While the tail fin may appear to have a crowntail-like shape at first glance, upon closer inspection there is often less than a 30% reduction of the fin membrane, which sets them apart from crowntails. The body size of a combtail will also likely be larger than that of a crowntail.

Conversely, a Crowntail betta has been selectively bred over several generations to give it an angular profile and even more dramatic branching in the tail fins with a 50% reduction or more in the fin membrane. This gives the fish sharp angles and edges as opposed to the more rounded shapes of the Combtail. The body size and shape of a Crowntail are also typically smaller than that of a combtail.

Both types of bettas are visually striking but will require different levels of care in order to stay healthy and vibrant.  Overall, by looking at fin reduction percentages as well as body size, one can easily distinguish between a Combtail and a Crowntail betta.
