Metronidazole is an antibiotic which can be used in saltwater aquaria. I have no experience with using it to treat fish diseases. I also have rarely seen the moderators recommend it.
The only antibiotics which can be used in marine aquaria are ones which leave the bacteria responsible for the cycle alone. Antibiotics are usually not recommended to be used in a display tank because some of the other breakdown processes will be inhibited and waste products may accumulate.
In Humans, metronidazole is used primarily for anaerobic bacterial and internal protozoal parasitic infections. Unfortunately it seems to have no effect against ectoparasites like ich. It won't do any good. It is more likely to kill off some of your beneficial worms in your live rock and live sand.
I would also be very careful about using a medication for another species in a fish tank. There are many other products in most medications (binders, coatings, flavorings, syrups, preservatives, etc) which could cause harm even if the medication was safe.
Hope that helps. One of the moderators could probably give you a list of diseases that could be treated with it. I just don't have that information.
