属的矮人的绑住属Centropyge和Paracentropyge是我们最喜欢的礁鱼之一，部分原因是它们出色的颜色变形和杂种。我们一直对这些异常人物的多样化感到着迷，并且似乎遇到了一些新事物！
On that note, I have to share this unusualCentropyge sp.在我的护理中，在伦敦的一个私人收藏中出现了。这只小鱼似乎只能被描述为“ piebald”颜色，这与更经常见过的颜色不同，尽管绝不是“ koi”和Xanthic的畸变。在我担任水族馆的岁月中，从一般的书籍和互联网上拖曳，我还没有在矮人的天使中看到这样的“ pibalding”的例子。
While fish sporting the‘Koi’ or xanthic morphoften change, or even revert back to wild type colours, piebalding can be caused by a couple of different conditions: A true piebald animal has genetic mutations that, from its embryonic development, leave patches of its skin devoid of either colour producing cells or, the presence of these cells but the inability for them to function.
皮肤状况白癜风, that occurs in people, could be said to be the most similar in terms of appearance to the mystery dwarf angel, as well as shed light on it’s potential cause. In humans suffering from vitiligo, white, melanin free patches appear on the skin; mostly the extremities, or areas exposed to the sun.
The vitiligo condition is not fully understood, but causes are thought to include auto-immune problems, overactive thyroid, or issues with the nerve endings in the skin. Unlike genetic piebaldism, vitiligo manifests later on in life, but in both cases the white skin patches are usually permanent.
After seeing this little fish, it got me thinking about the color morphs thatCentropyge展示。如果遗传馅饼是从产生颜色的遗传剂中掩盖了体内的区域，那么“锦鲤”的颜色和过于黄色的黄色，矮人天使有什么用？
“ Koi”和Xanthic Fish的问题之一是它们经常随着水族馆的时间而变化。在某些情况下，恢复了经典配色方案，这与他们的亲戚保持一致。Unusual color morphs, being rare and in turn highly desirable, do not always make for good value for money, if your prized mutant is going to change back to a bog standard example of its species!
在这种情况下，我们必须看到过去的醒目和稳定的基因突变，例如真实的piebaldism，而质疑环境，以及可能影响异常颜色个体的特定生理因素，例如带有白癜风的鱼！
鱼类中最常见的颜色颜料是黑色素，类胡萝卜素和嘌呤。嘌呤（主要是鸟嘌呤）是结构性颜色 - 结晶物质，通过与光的相互作用产生鱼皮的光泽和反射性。但是，正是黑色素和类胡萝卜素使我们在不同的组合中发现了黑人的黄色范围。
这些颜料的生产将取决于鱼的饮食，而这些颜料的利用受鱼的神经和内分泌系统的控制。染色体，颜料在真皮中保存细胞，指示局部区域中色素的扩散或浓度，对环境和荷尔蒙提示做出反应。
因此，也许具有“锦鲤”色素的鱼类具有饮食不足的结合，导致损失一种颜色色素沉着的“渠道”，或者对色谱区域的局部破坏？在人们中，白癜风表现出皮肤中黑色素的丧失，但是在鱼的皮肤中，色素相互作用较大，也许我们看到了更大的结局可变性。
可以说，压力，疾病，身体创伤或其他环境因素可能导致其配色方案的一部分？从五彩鱼的鱼中滴下黑色素，我们留下了xanthic individual。放下类胡萝卜素并调整嘌呤，我们可以遇到蓝色的变形，最常见于c .二色的,C. bispinosus和C. Potteri。
这可能就是为什么“锦鲤”颜色不稳定并随着时间而变化或恢复的原因。环境因素可能会发生变化，并且通常处于通量状态，而在诸如piebaldism的情况下，存在遗传空白，无限期地剩下无贫瘠的地区。一条具有最类似人类的白癜风的鱼可能像异常一样Centropyge，展示白色斑块。但是其他鱼类，三色scopas唐斯spring to mind, may be showing symptoms of a different magnitude, but of the same condition.
One suggestion as to why angels have adopted a xanthic coloration has been offered due to breeding. Of course many species of fish take on nuptial dress, but it was suggested (by F. Walsh in the Debelius, Tanaka, Kuiter, 2003 book on Angelfishes) that aberrant xanthic morphs of中央双色出现在产卵高峰期间的一年中的某些时间。但是，如果是这种情况，那么肯定会更重要的是吗？
It seems unlikely that such unusual nuptial coloration would manifest in just a handful of individuals, in just a few species of what could be considered a closely related family. However, perhaps collecting pressure, having removed specimens that kept to an archetypal colour scheme, has left fish that display less than perfect colors to breed, raising the percentage of potentially aberrant genetics, and the propensity for a particular fish to exhibit variable coloration.
关于异常颜色的外科医生的明显增加，这一理论已提出，在这种情况下肯定是一个合理的。我认为，如果这些鱼类出现在贸易中的丰富性和收集是针对其产卵活动的数据，那将真的很有趣，因为这似乎是一个很好的研究领域。
In regards to my London piebald angel, we are still unsure as to what species it actually is. C.Flavissimais typically a bright lemon yellow fish with blue highlights around the eyes, fin margins and operculum. There seem to be remnants of these on our aberrant individual. At the same time, there is a strong argument for it being aC. heraldi, due to its facial profile, as well as the eye coloration. There is even the possibility of aC. Flavissimaxheraldi在这种情况下，关于颜色，任何事情都会发生。当然已经观察到女性C. Flavissimachange color to almost white during courtship and spawning.
在这个异常的个体的情况下，如果是由piebaldism引起的，则应保持这种方式。就鱼紫象而言，它们可能会散布！只有时间会给出答案。这些经常是这样的Centropygecolor morphs, only time will tell.
