常规的盐水智能读者经常在保罗·B（Paul B）的帖子中看到对他们的参考。他们到达我们的水族馆，没有登机活岩，在活沙或岩石上的珊瑚标本上。乍一看，它们看起来像是小昆虫在岩石上刺伤或散落在玻璃上的昆虫。
我说的是“豆荚” - 不是入侵身体抢夺者kind (though we haven’t ruled that out completely with Paul B.), but the tiny crustaceans known as amphipods and copepods.
Amphipods
我们将讨论的第一批豆荚（Amphipods）比Copepods大得多，当它们在岩石工作中争夺时，可以轻松地用肉眼看到，通常是在灯光熄灭之后（它们在白天往往会使自己稀缺以避免捕食）。这些类似虾的微透质者通常在1/8至1/4英寸的范围内，偶尔出现“ whopper”，看起来像是带有多个段和很多腿的逗号。它们在某种程度上被压缩（一侧扁平），通常呈灰色至褐色。
copepods
Copepods比两亲脚架更细微，只能达到毫米左右。因此，当用肉眼看时，它们通常是在水族馆玻璃上或水柱上蜂拥而至的小白色斑点。在放大倍率下观察到，它们的身体模糊地泪流出触角。
What should you do about them?
Tiny bugs swarming your live rock and aquarium glass? No good can come from that, right? After all, what are the odds they won’t go rogue on your corals and/or fish? So what should you do about such an infestation? Kill, crush, destroy? Call in the “Orkin Man”? Nuke the tank with bleach?
以上都不是！只要把它们放在他们所在的地方，请感谢您得到它们。这些“豆荚”不仅是无害的，而且实际上是有益的，因为许多鱼都喜欢吃它们。（注意：关于copepods，我指的是常见的自由速wim速类型，而不是寄生物种，例如折磨的“红色虫子”Acropora珊瑚。）
In fact, if you want to succeed in keeping普通话, pipefishes, or other fish species that feed primarily or exclusively on live microcrustaceans, you’ll want to have as many pods in your tank as possible, which might mean actually purchasing pods (they’re available from various online sources) to replenish their population from time to time or culturing them in arefugium连接到您的水族馆。
现在，如果我们能以某种方式证明保罗·B（Paul B）不是“豆荚人”之一！
