We’ve come to the final installation of our three part mini series featuring the private fish collection of Kevin Kohen. This last post covers Kevin’s nano tank, so it won’t be a long post as there aren’t many fish in here. However personally, this is my favorite tank of his and it is a true heaven for rare fish geeks. Good things come in small packages, and in this nano tank Kevin has three super rare fish.
在看看凯文的纳米超级巨星之前，我们将首先介绍更常见的鱼。Assessor randalliused to be unknown in the aquarium trade, and the only two species anyone ever knew about was the yellow assessor (Assessor flavissimus) and the blue Assessor (Assessor macneilli）。
It wasn’t only in the last couple of years did ORA manage to offercaptive raisedspecimens that this fish became popular and more widely known. Like all评估员,A. randalli通常发现在野外的悬垂和壁架下倒置，并且在昏暗的水族馆环境中可以很好地做到。美丽的蓝色光泽只有在侧灯下或用闪光灯拍照时才能看到。亲自，鱼是非常漆黑的蓝色。
典型的小丑鱼由pair of ultra Picasso clownfish. This pair takes refuge in the corner of the tank and is showing spawning behavior. A juvenile and very nasty black tang also takes refuge in this tank, and will be removed soon as it grows and because it’s mean and horrible to everything in it.
现在，真实的东西！真正激起我兴趣的三条鱼中的第一条是超级罕见的，也很漂亮Nemateleotris helfrichi(Helfrich’s firefish) that originates from the Cook Islands. Unlike the normal Marshall islands Helfrich firefish, those coming out from the Cook Islands sport a totally different colored head. The magenta head stripe and black “mustache” sets this apart from the normal ones we see so often.
值得注意的另一件事是，库克群岛紫色的头赫尔夫里希（Helfrich）的消防鱼的大小是马歇尔人的两倍。有趣的是，类型的位置N. Helfrich我是库克群岛，而不是马歇尔的岛屿。这意味着紫色的变体是其描述名称的“类型物种”，而黄色头的马歇尔变体是较新的形式。谁知道，黄头赫尔夫里希的火鱼实际上可能代表了一个单独的物种。
The second super exciting fish for me to see in Kevin’s nano tank was aPlectranthias altipinnatus。This little guy belongs to a group of fish I hold very dear to my heart.Plectranthiasis a genus of smallSerranid低音大多是秘密和秘密的。就分布而言，这是一个积极的属。
Plectranthias除了南部和北极，在每个主要海洋中都有代表。它在太平洋和印度洋的温暖水域中达到了最大的发展，而在大西洋，它仅由一种物种代表（P. garrupellus); There may be another undescribed species in Curacao along withP. garrupellus。
In the aquarium hobby, only a handful ofPlectranthias提供给稀有鱼爱好者。他们稀缺的主要原因之一是，所有成员都非常秘密，并保持着岩石工作迷宫。他们收集的另一个限制因素是深水的倾向。
许多物种，例如P. garrupellus,are found in depths exceeding 200ft. Relatively shallower dwelling members such asP. longimanus,P. fourmanoiriandP. nanusmay be caught by conventional scuba, but because of their cryptic nature, are often gone unnoticed. Kevin’s nano aquarium is home to one member from the latter.
Plectranthias altipinnatusis a small, expensive and rare species that most closely resembles the aquarium staple,P. Inermis。人们认为这是日本特有的，那里几乎所有水族馆标本和水下照片都被拍摄。
There are two poignant pieces of information we would like to highlight with regards to this species, and Kevin’s specimen. According to numerous underwater photographs ofPlectranthias altipinnatus，除了进入日本市场的标本外，这种鱼似乎有两种“形式”。
The first and less common form appears to have a very clear separation of colors on its body, being white ventrally and red dorsally. This form can be seen in the pictures above and below, and is also the form that is currently living with Kevin.
第二个也是更常见的形式P. altipinnatus, has no clear distinction of body coloration. Both forms ofP. altipinnatus在第二背脊柱上拥有丝状旋钮，从不起眼的凹凸到非常突出且引人注目的叶子的大小不等。
两种形式差异的原因尚不清楚，并且可能只是颜色变化。但是，这些颜色形式都存在于少年和成年人中，因此它使信息更加朦胧。他们可以随意改变一生的颜色，还是像那样天生？目前我们尚不可用该物种的整型图片，因此我们不确定哪种形式代表类型物种。
我们想指出的另一件有趣的事情是该物种的收集位置和分布。P. altipinnatuswas thought to be found only in Japan. The specimen that Kevin has however, was an import from the Philippines. It was collected along with the similar and more commonplectranthias inermis。
This is the first time we’ve heard ofP. altipinnatuscoming out from the Philippines. It’s not that surprising actually, considering how secretive and “deep” these fishes live, it is likely that their range extends further than what was previously documented.Plectranthiasis an amazing genus indeed with numerous “known-unknowns” awaiting description, and there are probably a lot more “unknown-unknowns” waiting to be discovered.
如果你们中的任何一个人实际上仍在阅读，并且在那个书呆子之后没有失去兴趣plectranthias inermis, then here’s the last exciting nano fish that takes residence in Kevin’s nano tank. The beautiful and illustrious龙型是一条惊人的鱼。我爱烯烃, maybe just as much or even more thanPlectranthias。It is a hardy and easy going genus that offers a wide range of species in a wide range of sizes to the aquarist.
LikePlectranthias,烯烃积极分布在世界各地，并由许多物种代表。大多数人非常深，许多人非常未知，可以为潜在的科学发现提供巨大的贡献。话虽这么说，也就不足为奇了l . tonstrinumis found in a wide geographical range.
我们已经在我们的上一篇文章, where we have found examples of this fish in Japan, Tahiti, and most recently the Philippines. Kevin’s specimen came from the Marshall Islands, where it is likely to be one of the first collected from there.
I’ve had the good fortune and luck to have been able to travel around the world and see so many rare fish that I personally find so captivating. However, the three fishes highlighted in this post, including this烯烃, are some that I have not seen before in person, and that rush of excitement that comes with a “first time” is something that I cannot put in words.
Maybe it’s a fish geek thing, but for those out there reading this who can connect on the same wavelength, perhaps you know what i’m talking about. We really hope you have enjoyed our recount of Kevin Kohen’s fish collection. We’ve saved this nano tank post for the last because personally we were most excited for it. Which one of Kevin’s tanks did you like best? Let us known in the comments below.
