Standard Breeds of Ornamental Betta Fish in Thailand (Short Fin Single Tail)
A Short Fin Single Tail betta has a caudal fin approximately one-third the length of its body and a body form consistent with its breed.
Type 1
Round Tail Plakad
Body
The body is cylindrical and laterally compressed, complete in form, evenly long and slender, and equal in size on both sides.
Pectoral Fins
The fin rays are unbranched, 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 breed’s distinctive identity.
Pelvic Fins
The starting point of the fin base must be around the middle of the body toward the caudal fin. The dorsal fin is slightly higher than the caudal fin. When spread, it overlaps and touches the first caudal-fin ray. The fin rays are unbranched, which is considered a distinctive characteristic.
Anal Fin
The edge is smooth, long, and slender, with a slight curve rather than a straight cut. The fin tip is pointed to preserve the breed’s distinctive identity. The fin rays are unbranched, which is considered a distinctive characteristic.
Caudal Fin
The caudal fin has a rounded Round Tail form similar to a fan. The caudal-fin rays branch twice in equal form, except for the uppermost and lowermost rays, which branch no more than twice; either one or two branches are permitted. Their length should be no more than approximately two-thirds of the longest caudal-fin ray, creating the clearly curved tail form of the breed.
Type 2
Spade Tail Plakad
Body
The body is cylindrical and laterally compressed, complete in form, evenly long and slender, and equal in size on both sides.
Pectoral Fins
The fin rays are unbranched, 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 breed’s distinctive identity.
Pelvic Fins
The starting point of the fin base must be around the middle of the body toward the tail. The dorsal fin is slightly higher than the caudal fin. When spread, it overlaps and touches the first caudal-fin ray. The fin rays are unbranched, which is considered a distinctive characteristic.
Anal Fin
The edge is smooth, long, and slender, with a slight curve rather than a straight cut. The fin tip is pointed, which is considered a distinctive characteristic.
Caudal Fin
The caudal fin has a Bodhi-leaf shape. The caudal-fin rays branch twice in equal form, the tip is pointed, and the rays at the tip do not branch, which is considered a distinctive characteristic.
Type 3
Crowntail Plakad
Body
The body is cylindrical and laterally compressed, complete in form, evenly long and slender, and equal in size on both sides.
Pectoral Fins
The fin rays are unbranched, evenly long and slender, and not bent. The fin edge is smooth or slightly serrated, with a rounded tip.
Pelvic Fins
The starting point of the fin base must be around the middle of the body toward the tail. The dorsal fin is slightly higher than the caudal fin. When fully spread, it overlaps and touches the first caudal-fin ray. The fin has serrations resembling spines.
Anal Fin
The fin is long and slender with serrations resembling spines. The serrated length is one-third of the anal-fin length.
Caudal Fin
The caudal fin has spine-like serrations resembling a crown. The depth of the spines is no less than one-third of the anal-fin length.
Type 4
Halfmoon Plakad
Body
The body is cylindrical and laterally compressed, complete in form, evenly long and slender, and equal in size on both sides.
Pectoral Fins
The fins are straight, long, and slender, with pointed tips and smooth edges.
Pelvic Fins
The starting point of the fin base must be around the middle of the body toward the tail. The form is rounded, and the fin rays branch slightly at the tips. The dorsal fin is slightly higher than the caudal fin.
Anal Fin
The edge is smooth, long, and slender, with a slight curve rather than a straight cut. The fin tip is pointed.
Caudal Fin
The caudal fin is almost semicircular and half-moon shaped. The caudal-fin rays branch into no fewer than four rays. The caudal fin spreads to no less than 180 degrees when the fish flares, and the upper and lower outer edges form angles resembling the letter “D”.
Type 5
Dumbo Plakad
A short-fin betta whose fin structure and body conform to its breed, but whose pectoral fins, or ear fins, are exceptionally large—more than twice the normal size—giving it the name “Dumbo Plakad”.
Type 6
Giant Plakad
A short-fin Giant Plakad whose fin structure and body conform to its breed, but whose 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.
