Poma实验室最近高调宣布,他们对盖刺鱼科基因的研究取得了突破性的进展,通过近亲繁殖培育出了全新的物种,黄金蝴蝶神仙鱼。金蝴蝶是一种绚烂的海水鱼,它们拥有墨色的身体,黄色的尾巴,以及那大胆热烈的亮蓝色条纹穿巡全身。

 

金蝴蝶神仙身上的蓝纹随着个体以及产地的不同都有所变化。Poma实验室利用这一特性创造出了新物种,黄金蝴蝶神仙鱼。



 

金蝴蝶神仙在很多年以前我们就能进行繁育的品种了,我们有几对种鱼产卵。令人惊讶的是,我们在他们的后代里发了突变的个体,几年后,我们发现一对种鱼的后代身上的蓝纹细且密集,我们把它们单独提出来进行下一代的繁殖。

 

即便这种神仙鱼幼年其实依旧是黑色的身体,与成熟中的个体得蓝色条纹形成鲜明对比,当黑色逐渐褪变成棕色,蓝色条纹在其脸部开始显现时,这对种鱼的第三代子孙出现的黄蓝色条纹与上一代明显不同。

 

我们发现了一些非常酷的特征,比如珍珠蓝的眼睛和一些古怪的条纹,以及背背部颜色的微妙变化。然后,在第三代子体中我们发现,幼鱼小到几乎没有条纹,和少许条纹像模糊的迷宫一样遍布全身。

 

最令人兴奋的是,Poma实验室所培育的新种金蝴蝶神仙与其他幼体都不一样,我们不知道这些幼鱼未来会变身成什么样,让我们期待这些黄金蝴蝶神仙长大之后带给我们的惊喜吧。

Poma Labs has really been ramping up their line-bred angelfish releases with the announcement of their newest breakthrough in Pomacanthid genetics, the ‘yellow’ blueline angelfish. A normal blueline angelfish is a gorgeous tropical marine fish with a dark body, bright yellow tail, and a series of boldly patterned blue lines across the head and body. 

 

The thickness and number of blue lines varies with the individual and where they come from and this is the trait that Poma Labs experimented with to create a very interesting new strain of Chatodontoplus septentrionalis. 

 

“Blueline angels were one of the first species we had success with many years ago. We had several pairs of these amazing angelfish spawning, but surprisingly, we noticed very little variation among the offspring. After a few years, we found a pair that produced thin line and thick lined offspring. We raised these up and crossed the offspring.”

 

Even when they are young the blueline angelfish display a dark body color which helps to contrast their developing blue lines. The black eyestripe fades to brown and reveals the rest of the blueline pattern as it starts to show on the face. But this new third generation of captive bred yellow blueline angels are quite different from an early age:

 

We found some pretty cool traits popping up, like blue pearl eyes and some wacky stripes along with a subtle shift in the background color. Then, in the f3 generation we found these. Yellow angels with little to no striping and a few with faint maze like patterns throughout the body.

 

The most exciting part of this new ‘strain’ from Poma Labs is that we know the fish are special because they already look quite different as juveniles. But we don’t yet know what these fish will turn into, so it’ll be an awesome surprise for whoever gets these yellow blueline angels and grows them up first.
