白色浇灌的外科医生是这种唐犬，因为它缺乏颜色，因此被许多人所忽略了，但受到更多经验丰富的珊瑚礁的追捧和赞誉。也称为芥末汤，有时是珠宝唐，阿斯塔鲁斯·古塔图斯（Acanthurus guttatus）来自浅水，在印度太平洋，从毛里求斯到夏威夷，在夏威夷几乎到处都是。
它最喜欢的栖息地是小于8m/25'深的潮流区域，通常没有珊瑚，藻类在光线亮的水中扩散。它的数量从10到100多个或更多，均匀地放牧，既放牧丝藻和钙质藻类，却以白水after的易于和精度导航强流。

Speak to someone who has owned a Whitespotted surgeonfish and they will tell you that no flow is too strong for them, and we have seen them skit in and out of flow from the most powerful wavemakers. 100 times turnover is not too great for these surfers and they crave the high oxygen that comes with it, to the point that one aquatic retail store told us theirs couldn’t have too much oxygen. The white spots on the flank are also believed by some to offer camouflage in the bubble-rich waters they inhabit.
Guttatus可以达到约10英寸的总长度，但是像许多盐水鱼一样，我们看不到它们在家庭水族馆中的大小。购买可爱的3英寸少年，因为他们旅行和适应能力更好，并且可以将其断奶为干燥和冷冻的食物。将它们用于蠕虫，然后每天经常喂食它们，以便他们直面时保持椭圆形。
它们不是侵略性的唐斯，但会与任何居民斑马瘤或阿斯图鲁斯一起竞争，因为他们将争夺放牧领域，因此请谨慎与其他唐斯混合。由于它们的活动，A.guttatus在少年时需要至少180加仑的坦克，我们已经看到他们使用每一英寸的水量，六倍。我们还没有看到它们在公共水族馆以外的学校中维护，所以最好的是，它们将适合SPS主导的设置以及随附的明亮，白光，混乱的流动和微藻。
尽管丰富的浅滩,价格of A.guttatus helps to keep them exclusive versus other shallow-loving relatives like A.triostegus, and they often sell for between $200 and $600. It is worth making sure that they have been rested, medicated, and are feeding for that kind of investment, and avoid large, dark-colored, recently shipped adults, as we find they just don’t take as well to reef aquarium life.
