A throwback to our大阪评论看到我们简短地提到了令人难以置信的棱柱形美Tosanoides flavofasciatus. LikeLiopropoma Aurora, this species, especially this particular specimen is deserving of a full and separate post to really showcase its beauty and story.T. flavofasciatusis joined by only one other member in this genus and is found primarily in Japan, although its range extends to Palau as well.
T. flavofasciatusis the commoner of the two species, the other beingT. filamentosus. While it cannot be considered rare, it is by no means a frequent sight. The species in itself is not rare in the wild, and like most Anthiines, are found living in harems with numerous females and a single male. In the aquarium trade, both species ofTosanoides是从日本收集的，他们在国内市场出售。由于成本高和稀缺，很少有人出口。
T. flavofasciatus经常出现在Blueharbor，船只和泻湖等高端鱼类商店中。但是，该物种通常以女性或少年为代表，而男性仍然是一种罕见的商品。像这样的大型令人惊叹的男性是一个完全不同的球游戏，而且极为罕见。这里的这个人是我见过的该物种中最好，最大，最壮观的代表之一。由于即使是透明的女性和少年也很昂贵，因此该物种仍然被搁置在本地市场上的商店内，这并不奇怪。
Tosanoidesis an unusual genus, and morphologically distinct from many other Anthiines. They’re rather high profiled, stocky, and have large rounded ventral fins. In both species, their fins and especially the tail are decorated with filamentous thread fin extension.T. filamentosus极大地长鳍accessories, and for that it is deserving of its name.
Both species are deepwater and are normally found below 200ft. In cooler months, and especially winter, they swim up to shallower waters where temperatures are still cool enough at depths of 110-160ft. Like all members of their subfamily, both species ofTosanoides是性二分法的，并且在一定程度上也是二态的。这两种物种的女性都是纯正的，没有鳍长的长度，通常没有任何螺纹细丝。女性T. flavofasciatushave colors only on their fins and face.
The males are simply stunning. InT. flavofasciatus, males are yellow striped, which is a literal translation from their specific epithet “黄牛“. The tails is unique in having an oblique separation, with colors only on the lower lobe. The top portion remains clear. This species is extremely fascinating in its coloration, and it reminds me very greatly of certain tropical butterflies to sport structural coloration due to refractive scales.
In images captured by flash photography,T. flavofasciatus在黄色之间出现粉红色或紫色。这种颜色虽然很有吸引力，但并不是生活。“粉红色条纹”具有折射品质，只能在人身上或视频中得到欣赏。粉红色的条纹具有淡淡的，几乎是钢铁般的光泽，其衍射光线具有不同的角度。他们亲自是丁香，几乎是蓝色的。从某些倾斜角度上，鱼看起来像粉红色。但是，当摄像机闪光灯发射时，光线会使这种特征变平，而钢的品质显得平坦和粉红色。
野外男性标本的上面的视频非常清楚地显示了这一现象。要特别注意这种颜色，并注意它比粉红色更重要的丁香蓝色。快速的Google图像搜索该物种否则会显示出，大多数照片以粉红色代表。除了白平衡校正之外，由于这种效果，颜色很难复制。大多数照片显示T. flavofasciatusin pink, the opposite occurs for videos and most appear true to life as lilac-blue.
Also notice the large group of females near the 40 second mark. They are comparatively drab against the stunning male. The large stunning individual in this post was hand carried back to Singapore from Osaka, and now lives very happily with a friend. You can expect updates on this fish in the future.
To end this post off, here’s a quick look atT. filamentosus. This stunning specimen from Lagoon shows a beautiful male in prime coloration. Notice the long trailing filaments that give this species its name. We won’t elaborate too much on this species, so as not to steal the Awesome Fish Spotlight onT. flavofasciatus. We’ll keepT. filamentosus另一天！
