Information on how to use ornamental fish medications safely.
Medications available to the fish hobby are becoming increasingly more difficult to source due to tightening regulations and demands. And, some countries have made fish treatments prescription only, requiring a veterinary script. We are lucky in the United States to be able to still have access to these medications, but must use them correctly to avoid a resistance buildup, which leads to the medication becoming ineffective. This has already happened with some fairly common products.
Resistance is created by under dosing through using too low a dose or by not using for an appropriate number of days. Once resistance is built the medication becomes ineffective in treatment. We need to use the products available appropriately or may find that they are removed from the shelves and lose our ability to help our pets when their immune system needs additional support.
