Bristlemouth Surgeonfish的Ctenochaetus.genus are some of the most perfect aquarium fish with a size, behavior and disposition that seems tailor made for a life in a reef tank. There are many species available in the aquarium hobby but today we want to take a look at the twins of this group which have very disparate natural distributions in the wild.
黄眼kole唐，Ctenochaetus.strigosus，和印度金戒指或唐，Ctenochaetus.truncatus，是两个非常相似的鱼，黄色眼睛和巧克力棕色的身体。前者曾经是咸水水族馆业余爱好中最常见的外科鱼之一，但后一种物种现在已经成为近年来更常见的立场。
正如名称所表明的那样，Squaretail Tang在外科医生属中有一个不可结观的扁平的尾鳍，主要具有Lyre形的尾巴。身体颜色可以从浅褐色到几乎黑紫红色的着色，带有黄色的眼睛环和身体上的小点。
The light colored spots can sometimes appear bluish but the yellow around the eyes is much smaller than in the better known kole tang. Despite their very similar appearance, the squaretail tang lives very far from the Pacific Ocean range of the Hawaiian endemic being widely distributed throughout the Indian Ocean so there’s no real chance of discovering natural hybrids of the two in the wild.
The Kole tang,Ctenochaetus.strigosus, was once one of the most common saltwater aquarium fish in the hobby being collected from Hawaii but the supply has since been completely cut off when ornamental fish collecting was banned in the Aloha state. This rich brown colored surgeonfish has thin blueish stripes over most of its body which turn into spots on the face, and a bright yellow patch covering its eyes.
一旦售价约50美元或更少，Kole Tang就没有展示鱼类，只有它的眼部贴片，只有其整体外观提供任何颜色。当鱼大约三到四英寸时可能是一个微妙的美感，但由于它成熟的蓝色条纹变得更加明显，未配对的翅片变得更加伸长，尾巴变得高度的氛围，在提示处发展飘带。
We are fortunate enough to be in possession of large kole tang which is just a few centimeters shy of its maximum size of 18cm or seven inches, and its mouth is showing a lot of blue while the pectoral fins are a catchy light orange under ideal lighting. We’ve seen thousands of kole tangs and even kept a few in the past but we had no idea how beautifulCtenochaetus.strigosuscan become when large and mature, so it’s a shame that these are no longer widely available in the aquarium hobby.
The Bristlemouth TongsCtenochaetus.don’t get nearly as much fanfare as theirZebrasoma和acanthurus.relatives but they are even better at eating algae, being (relatively) docile, andnot超越平均家庭水族馆。这组近乎完美的水族馆鱼中有许多其他物种，所以如果你从来没有被保留一个，那么下次你在当地的鱼店遇到他们时肯定会考虑一下。
