玫瑰尾鬥魚
The Rosetail
http://www.bettysplendens.com/articles/home.asp為追求最完美的半月鬥魚,經由淘汰育種,培育巨大或直挺的尾鰭,鬥魚尾鰭樣式已經演化出一新的支系,著名的玫瑰尾鬥魚。
The quest for the perfect halfmoon by selectively breeding for branching and straight caudal edges has given rise to a new development in the betta splendens tailforms - the Rosetail.
玫瑰尾鬥魚主要特徵就是三個極大的奇鰭,尤其是極度擴展和部分重疊的尾鰭,形成玫瑰花一樣的外觀。玫瑰尾鬥魚的最終型態會形成非常獨特的「羽毛尾鬥魚」。
The main characteristic of the rosetail is the excessive branching in all three unpaired fins, especially the excessive branching and the overlapping rays in the caudal, which produces a ';rose-like'; appearance. The extreme form of Rosetail can produce the very unique ';Feathertail'; betta.
飼育者用玫瑰尾鬥魚培育半月鬥魚要非常小心,過度雜交可能產生無法正常游泳或突變的魚。這些弊刁魚通常體型小,腹鰭短,魚鰭塌陷無力。
A breeder using Rosetail bettas in their halfmoon lines has to be particularly careful of excess- fish who cannot swim properly, or who carry the trait into the mutation that has been coined ';X-Factor Fish'; - fish with poor scales, shorter ventrals and collapsing finnage.
