This question does not only apply to the Fish Mox (Amoxicillin) antibiotic. Almost all of our antibiotics have a regular strength, such as Fish Mox, and an extra strength, such as the Fish Mox Forte. Both antibiotics have the same ingredients in them; both are filled with Pharmaceutical Grade Amoxicillin. The only difference between the two is the strength of the antibiotic that is in each capsule. The regular Fish Mox antibiotics have 250 mg of Amoxicillin in each capsule, whereas the extra strength Fish Mox Forte has 500 mg of Amoxicillin in each capsule.
The 250 mg and 500 mg dosage and strength is consistent with most of our fish antibiotics. The following products all have the regular 250 mg capsules or tablets and their 500 mg counterparts:
However, there are a few outliers to this model.
The Fish Tapes and Fish Tapes Forte have the same concept of having a regular and extra strength.
Fish Tapes has 34 mg of Praziquantel in each capsule.
Fish Tapes Forte has 170 mg of Praziquantel in each capsule.
The other type of outlier to this model is the Fish Sulfa Forte. Fish Sulfa Forte has 800mg of Sulfamethoxazole and 160mg of Trimethoprim in each tablet. The odd thing about the Fish Sulfa Forte is that there is no regular Fish Sulfa, there is only the Fish Sulfa Forte.
