I was wondering if anyone had used this combination. I don't want to over medicate my fish but recently an oscar I have started lying on the bottom of the tank restless and doing nothing for a few days. Every now and then he comes to the top to eat, but it seems as though he has some sort of internal bacteria infection as there are no visible signs of anything externally. I was thinking using a combination of all three any other suggestions? As far as the quality of my water, its tip top, everything within spec and then some, so thats how I got to the conclusion of it having to be an internal infection
