There’s a reason I chose to spotlight达斯基鲁斯·阿鲁阿努斯，在此个人资料中，骗子或三条条纹的dam selvish。“加勒比”克里斯和我很快将与该物种的四名代表相匹配，他们声称自己是我们当地一家咖啡店中的一个大型海洋水族馆。这家商店的老板史蒂夫（Steve）以这四个洪堡为准，这不会遵守大多数新的坦克伴侣，并希望看到他们以任何必要的方式被捕获和重新安置，而没有（或可能包括）动态坦克。
Chris and I figure that between the two of us, we should have the mental prowess to outsmart these little devils, so we’re currently brainstorming the capture techniques we’d like to experiment with over the next week or so (suggestions from fellow salties are most welcome). We plan to document the process on video, so stay tuned for updates.
不过，目前，让我们仔细看看我们的未来采石场：
Physical traits
D. aruanus, an Indo-Pacific species, is white overall with three vertical black bars on its sides, one extending from the leading edge of the dorsal fin through the eye and to the mouth, another at mid-body, and a third just in front of the caudal peduncle. The pelvic and dorsal fins are also black. Maximum length for this species is around 4 inches—quite a respectable size for a damsel.
I should note that a very similar-looking Western Pacific species in the same genus,D. melanurus，通常也称为洪堡少女（或Blacktail Humbug）。这个少女与D. aruanus因为它的尾巴上有第四个黑色乐队。同样，其背鳍上的黑色颜色在中体时被白色中断而不是连续。尺寸，该物种在3英寸左右较小。
In addition to looking very similar, these two species are much the same from the standpoint of behavior and care requirements, so everything said here regardingD. aruanuscan generally be applied toD. melanurusas well.
Feistiness
Hobbyists often buy humbug damsels in groups when they’re still young, cute, and relatively peaceful (the damsels, not the hobbyists), but, as with so many damsel species, those adorable juveniles eventually transform into highly belligerent, territorial adults that are poorly suited to the average community aquarium. Any tankmates chosen need to be large and assertive enough to shrug off the humbug’s aggression. Also, while humbugs may share branching stony coral heads in nature, they often won’t tolerate conspecifics in the same aquarium beyond the juvenile stage.
Feeding
这里没有任何挑战。D. aruanuswill readily accept most standard aquarium fare. Offer this omnivore a variety of small meaty and algae-based foods, and offer several small meals per day rather than a single large one. This species will even readily accept dry flake and pellet foods, like New Life Spectrum, which Chris and I both feed to our fish and heartily endorse.
Housing and reef-friendliness
我认为一个30加仑的坦克是最低住房D. aruanus，但请记住，如果您打算将该物种的成年人与合适的坦克伴侣保持相对，则需要更大的坦克。
从积极的角度来看D. aruanusmay become belligerent toward many other fishes sharing its space, this species is completely inoffensive toward sessile invertebrates and, therefore, a safe choice for reef systems.
