@Bradders I think I’m going to give a large water change a go. At this point it’s worth giving it a go I’d say, in the hopes it reduces the bad bacteria. The fish don’t have any sign of epistylis now and I’d rather get the bad bacteria out than leave the medicine in (I think). Or I may think on it. Ugh so frustrating. I feel like I’ve really failed my little fish when all I’ve wanted to do is my best for them.
