Possibly. There are many situations where it is necessary to change medication. Sometimes you are treating a parasite that is very medication resistant and requires a more powerful treatment, other times the medication you were using was simply the wrong kind to treat the infection. However, there are a few things that MUST be true before making this kind of swap.
- You have given your original medication enough time to work. The visible cysts caused by ich and other external parasites are all but immune to medication, and can take up to a week to drop off the fish when using a medication. In fact, ich infestations often look worse before they get better. Don't swap medications just because your current treatment did not cure the fish in a single day.
- You are certain that you are a parasitic infection like ich, velvet, or hexamita. Sometimes, an anti-parasitic medication will fail to work because you are not actually treating a parasite. Some viral infections like lymphocystis will show similar symptoms to ich (white cysts) while many forms of external bacterial infection can look remarkably similar to hexamita (tissue degradation on the face and fins). Research your fish's symptoms thoroughly to ensure that you are choosing the right kind of medication.
- Your fish and other aquarium inhabitants will tolerate the method of dosing you have chosen. Medications like MetroPlex can be added to a fish food to make an ich treatment that is safe to use in reef or planted aquaria. It is possible to dose the medication in the water instead, but this method of dosing is not considered safe for invertebrates or plants.
