Do understand that many times ,fish are beyond help but I applaud you for your effort.
Agree with Oscar Jim with regards to tank size for one Oscar and water qualtiy is paramount to the fishes survival.Ammonia and nitrites must read zero, and nitrates should be no higher than 20 ppm.
Metronidazole is best crushed up and mixed with food, but if fish is not eating,then treating the tank becomes necessary.
Have crushed up two 250 Mg pills of metro (not easily soluable) and treated at 500 mg per ten gal every ten hours with 50 percent water change between each dose for 7 to 10 days.
Lights must be off or med oxidises and temp should be 84 to 86 degrees F during treatment.(less effective at lower temps)
Would also utilize airstone at these temps.
Once the pills are crushed ,place the meds in half a glass of aquarium water and place in microwave until mixture comes to boil. Remove carefully, (will be extremely hot) and slowly add it to the tank.
This is the only way I have had any degree of success with Metro and ,,daily large water changes of 50 to 60 percent for a couple weeks ,would be my first choice of treatment.(before meds)
Quality pellet foods and frozen shrimp,fish,earthworms,crickets, krill,and NO feeder fish will also provide benefit.
If water quality is poor which very well could have been the problem berfore,,no medications will be effective. Clean water through water changes is often best medicine.
Metronidazole has no negative effect on biological filter and nitrifying bacteria to my knowledge and expieriences with this particular medication.Does have effect on anerobic bacteria.
