we actually had to do two rounds of treatment. One of our 3 fish shops had such a great health rate we didn't quarantine one of our purchases. Of course, we had popeye. One barb lost an eye, but after 2 rounds of treatment it was cleared up. Lesson learned on this one.

Pros: Did help with the popeye

Cons: Can't think of any

This is a good all-around wide spectrum antibiotic. Good for a variety of small fish diseases, does an excellent job of clearing things up as long as you don't over-use it.

Pros: This is a good all-around wide spectrum antibiotic.

Cons: The tank has to be sick to need the product ... I'd say that's a con.
