Short Fin Double Tail Betta Standard
Standard Breeds of Ornamental Betta Fish in Thailand
This standard covers short-fin double-tail bettas with a short, laterally compressed cylindrical body and a caudal fin approximately one-third of the body length. The caudal fin is divided into two clearly separated, balanced lobes by a central division.
Type 2.1
Round Tail DTPK
Body
The body is cylindrical and laterally compressed, complete in form, long, slender, and proportionate, and should be equal in size on both sides.
Pectoral Fins
The fin rays are branched, long, slender, and straight, without bending or crossing, and have pointed tips. Their length should be approximately one-half the length of the Anal Fin to preserve the variety’s distinctive identity.
Dorsal Fin
The Dorsal Fin base begins toward the head. Its tip is long, slender, and pointed, and is slightly higher than the tip of the Caudal Fin.
Anal Fin
The edge is smooth. The fin is long and slender, with only a slight curve along its upper edge rather than a straight cut. The tip is pointed to preserve the variety’s distinctive identity. The fin rays are unbranched.
Caudal Fin
The Caudal Fin is divided into two clearly separated upper and lower lobes by a central division. The Caudal Peduncle should have a clean division, and both lobes should be equal in size and fan-shaped. The caudal-fin rays branch only twice, except that the uppermost and lowermost first rays may branch beyond two into either one or two rays. These rays should be no more than approximately two-thirds the length of the longest caudal-fin ray.
Type 2.2
Spade Tail DTPK
Body
The body is cylindrical and laterally compressed, complete in form, long, slender, and proportionate, and should be equal in size on both sides.
Pectoral Fins
The fin rays are branched, long, slender, and straight, without bending or crossing, and have pointed tips. Their length should be approximately one-half the length of the Anal Fin to preserve the variety’s distinctive identity.
Dorsal Fin
The Dorsal Fin base begins toward the head. Its tip is long, slender, and pointed, and is slightly higher than the tip of the Caudal Fin.
Anal Fin
The edge is smooth. The fin is long and slender, with a slight curve along its upper edge rather than a straight cut. The tip is pointed to preserve the variety’s distinctive identity. The fin rays are unbranched.
Caudal Fin
The Caudal Fin is divided into two clearly separated upper and lower lobes by a central division. The Caudal Peduncle should have a clean division, and both lobes should be equal in size and shaped like Bodhi leaves. The caudal-fin rays branch only twice, except that the uppermost and lowermost first rays may branch into no more than two rays. These rays should be no more than approximately two-thirds the length of the longest caudal-fin ray.
Type 2.3
Crowntail DTPK
Body
The body is cylindrical and laterally compressed, complete in form, long, slender, and proportionate, and should be equal in size on both sides.
Pectoral Fins
The fins are straight, long, and slender, with pointed tips and no bending. Their edges are smooth or serrated like spines.
Pelvic Fins
The fin base begins on a vertical line toward the front. The fin rises slightly higher than the Caudal Fin. When fully spread, its front lower edge touches the first caudal-fin ray. The fin is serrated like spines, and the depth of the spaces between the spines is no less than one-third of the ray length.
Anal Fin
The fin is serrated like spines. The depth of the spaces between the spines is no less than one-third of the Anal Fin length.
Caudal Fin
The Caudal Fin is divided into two clearly separated upper and lower lobes by a central division. The Caudal Peduncle should have a clean division, and both lobes should be equal in size. The fin is serrated into split-tipped spines, with spaces no less than one-third of the Caudal Fin length.
Type 2.4
Halfmoon DTPK
Body
The body is cylindrical and laterally compressed, complete in form, long, slender, and proportionate, and should be equal in size on both sides.
Pectoral Fins
The fins are straight, long, and slender, with pointed tips and smooth edges.
Pelvic Fins
The fin base begins toward the front. The tip is long, slender, and pointed, and its height is slightly greater than the tip of the Caudal Fin.
Anal Fin
The edge is smooth. The fin is long and slender, with a slight curve along its upper edge rather than a straight cut. The tip is pointed.
Caudal Fin
The Caudal Fin is divided into two clearly separated upper and lower lobes by a central division. The Caudal Peduncle should have a clean division, and both lobes should be equal in size. The caudal-fin rays branch into no fewer than four rays. The outermost tips of the upper and lower lobes form angles like the ends of the letter “B”.
Type 2.5
Halfsun DTPK
Body
The body is cylindrical and laterally compressed, complete in form, long, slender, and proportionate, and should be equal in size on both sides.
Pectoral Fins
The fins are straight, long, and slender, with pointed tips and no bending. Their edges are smooth or serrated like spines.
Dorsal Fin
The Dorsal Fin base begins on a vertical line toward the front. The fin rises slightly higher than the Caudal Fin. When fully spread, its front lower edge touches the first caudal-fin ray. The edge is serrated like spines, and the depth of the spaces between the spines is no less than one-quarter of the Dorsal Fin length.
Anal Fin
The fin edge is serrated like spines. The depth of the spaces between the spines is no less than one-quarter of the Anal Fin length.
Caudal Fin
The Caudal Fin is divided into two clearly separated upper and lower lobes by a central division. The Caudal Peduncle should have a clean division, and both lobes should be equal in size. The fin has sun-like serrations at its tips, with spaces no less than one-quarter of the Caudal Fin length.
Type 2.6
Dumbo DTPK
A Dumbo Double Tail Plakad is a short-fin betta whose Caudal Fin is divided into two clearly separated upper and lower lobes that should be equal in size. Its fin structure and body conform to its variety, while its Pectoral Fins, or ear fins, are exceptionally large—more than twice the normal size. This characteristic gives it the name “Dumbo DTPK”.
Type 2.7
Giant DTPK
A Giant Double Tail Plakad is a short-fin betta whose Caudal Fin is divided into two clearly separated upper and lower lobes that should be equal in size. Its fin structure and body conform to its variety, but its size is larger than normal. Its body length, measured from the tip of the mouth to the base of the Caudal Fin, is more than 6.5 centimetres.
