Ik ben geen Betta expert maar het zijn toch twee kweekvormen van de betta splendens?
Zelfs dit is niet (altijd) aan de orde, als je heel strikt gaat kijken.
De Betta's uit de splendens 'group' - splendens, smaragdina, imbellis, mahachaiensis, stiktos en samorientalis - zijn zo verwant dat ze met elkaar kunnen kruisen. Bepaalde eigenschappen komen wat meer terug in de ene soort dan in de andere soort. Dit samen is gebruikt door kwekers om tot allerlei bijzondere eigenschappen te komen. Twee voorbeelden:
Understanding metallic genetics
(...)
The metallic phenomenon was introduced in our hobby by outcrossing Betta splendens to wildtypes from the betta genus like betta imbellis, smaragdina and mahachai [1,2]. Betta imbellis, smaragdina and mahachai naturally have a higher degree of iridescence on the scales which probably is an adaption to the murkier water in their natural habitat [3].

The origin of the "dragon" betta
According to Pichet (Interfish breeder team - Thailand), the first "dragons" were created by using a "super" red plakat, a red copper plakat and Betta sp. mahachai [8]. With some difficulty, the wild Betta sp. mahachai was crossed to the red copper plakat with the intent of preserving the Betta sp. mahachai traits in the offspring. Then a young male from this spawn was crossed to a super red plakat female. The third step was a mother x son backcross: the super red female was crossed to one of her offspring in a method commonly referred to as 'line breeding'. Although the body shape and finnage of the fry was not very good and some of them even showed malformations in the body, the color was there and the first dragon pair was born! The first "dragons" were developed by Mr. Tea. The "Red dragon V1" were first presented to the Thai public in the December 2004 edition of a magazine called "Fancy Fish" by the Interfish breeder team [9].

De eigenaar van deze website, die behoorlijk bedreven is in het kweken van Betta's en duidelijk een vergaande kennis heeft, vermeldde ons dat je bij de nakweek Betta's die je koopt - that is: de niet wildvorm varianten - (meestal) eigenlijk niet eens meer van Betta
splendends meer kan spreken.
