当我们护理中的一条鱼生病时，想要扔掉我们可以解决问题的每一种方法是完全可以理解的冲动。但是有时候，用药物或其他治疗急忙造成的弊大于利。
当治愈比疾病差时
有了一些鱼类疾病，提议的治愈实际上可能比疾病本身更具破坏性。在人类医学中，这被称为医源作用，拟议的治疗会引起其自身的严重问题。为了避免这种情况，水产师必须始终意识到拉丁语“Primum non nocere，”或“首先，不要伤害。”
Problems in developing an appropriate disease treatment can range from treating an aquarium with a medication or dosage that ends up being lethal to the fish to procrastinating due to indecision, again with fish loss as a result. In between these two extremes are using products that simply do not work as advertised, treating for the wrong disease, or trying too many different treatments.
仔细检查剂量并库存
在将任何药物添加到水族馆中之前，请务必仔细检查您的剂量计算。某些药物可能对敏感物种有毒，尤其是离子铜和氯喹。同样，水族基金会很可能想储备某些常见药物，因为诊断水族馆中的严重疾病只是为了发现商店已关闭，这是非常令人沮丧的。永远不要忽略早期症状，即“也许鱼会自己会变得更好”，因为这几乎永远不会发生。
Buyer beware!
当谈到水族馆药物时，要记住的另一个拉丁语是“买者自负”—“Let the buyer beware.” It’s unfortunate, but there is little control over the aquarium medication manufacturers. People can develop “cures” and sell them as effective treatments without ever having to prove that their product is safe or even works at all.
另外，请注意大多数“礁石安全”药物。业余爱好者对市场有强大的压力，要求他们开发可安全用于敏感无脊椎动物的药物。为了满足这种需求，制造和出售产品，但大多数尚未接受过效力测试。
治疗正确的疾病
Treating for an incorrect diagnosis is another common issue. Many diseases have symptoms that mimic each other and overlap. Aquarists may conclude that their fish has one disease, when it actually has another.
给予治疗时间
最后，当一个绝望的水产师尝试治疗时，就会看到“狩猎和啄食”，而当它似乎不起作用时，就会切换到另一个，然后再切换到另一个。问题是，许多渔业需要五到七天甚至更长的时间才能工作。您必须给他们适当的时间来完成工作。
