By: Greg Collinske

The convict tang is one of the most widespreadAcanthurus世界上以及我们的爱好中的物种。这些成功且适应能力的鱼类在整个印度太平洋和夏威夷的小组中都在巨大的学校中找到了巨大的学校，他们一直在努力在世界海洋中留下自己的印记。

在使用教育策略进行防御时，定罪者唐斯在尾巴的底部适应了一个欠发达的尾状脊柱或“唐”。这很少用于保护，因为它在其他各种外科医生中。

一些专家指出，夏威夷定罪者唐可能被证明是其自己的亚种Acanthurus triostegussandivicensis完全的with its own slight marking deviations. The Hawaiian species exhibits a black line beneath each pectoral fin, where other Indo-Pacific convict tang species are most often characterized by a black dot.

Convict tangs play a crucial part in keeping the reef ecosystem healthy.They are constantly grazing on fast-growing algae on the reef, which over time would impede coral growth and reproduction. It just so happens that the convict tang is equipped with a downward facing mouth, perfectly designed for picking off these algae growths.

Some of the wild species of algae consumed by convict tangs are known to carry a toxin called ‘Ciguatera’. This toxin is harmless to the fish; however, it can be toxic to humans and is considered poisonous if eaten.

定罪照顾

We advocate pre-displayquarantine为了在Tang物种方面取得最大的成功，这通常涉及在引入之前在单独的隔离罐中对外部和内部寄生虫，真菌和细菌进行治疗。在此期间，我们鼓励诺里海藻的补充喂养，以供不断的觅食机会。在此期间，可以很容易地对鱼的整体外观进行观察。

Aquarium size is critical for any species of tang for a couple of really important reasons; space for swimming, territory for its inevitable grazing, and where it will rest during the night cycle. We would recommend an aquarium 125 gallons or larger, this species does particularly well in reef aquariums due to the opportunity to forage over live rock daily.

Thought should also go into aquarium stocking to prevent aggression as much as possible; consider both species and space requirements especially with other surgeonfish species. If many different species are to be kept together we advise picking fish with a different body outline from a separate genus likeZebrasoma, Paracanthurus,Ctenochaetus，或者Naso.

定罪的唐人具有惊人的颜色图案，较小的体型，随意的自然和连续放牧的能力，将为任何已建立的礁石水族馆提供出色的补充，并考虑到一些考虑因素。
