The fish was treated with seachem metroplex on his regular NLS food bonded with the help of seachem focus ... a plentiful amount of metro and focus. It was gobbled up by the fish and this treatment was continued for 14 days (I believe). Initially, spironucleus was seen in the waste under a microscope and then, finally, no more.
I don't believe the water column was treated. I don't believe it was.
I also don't know to what extent metronidazole is absorbed into the body through the gut. I don't believe it's absorbed very much at all which is why it's used in humans for certain infections. If the water column is dosed, I wonder how well it will be absorbed into the the bloodstream (via the gills).
Note: After all the treatment with metronidazole, the fish still had white stringy waste as bad or worse than ever. Under the microscope
philipraposo1982
discovered a nematode infestation (capallaria, I believe). He treated the water column with levimasole 2 ppm and that was the end of that. I had considered this over until this recent thread opened up.
I wonder ... since there's stringy white waste ... well, what does that have to do with the bloodstream. If it were me, and I trust levamisole as completely safe, I'd dose the water column at 2-3 ppm.
After having rested on it for 2 nights, I'd also seriously consider the advice given by
RD.
regarding that asiain medication.

This might sound crazy, but what I do for discus is net them, dip a Q-tip in hydrogen peroxide, and swab the wound really well to kill anything in it. Just don’t get it in his eyes. Then return the fish to a clean tank and do frequent water changes to keep things really clean until it heals. Sometimes it takes a few weeks to heal over
Not crazy at all. Dabbing the area with a Q-tip was recommended by other very respectable members. I believe methylene blue was initially mentioned weeks or months ago but the idea is the same ... kill the pathogen/s and let the wound heal. When the wounds are new they can still heal over ... I've seen this with a course of metro and a change to larger, more frequent water changes. Older wounds from HITH won't heal. So al least he's caught this early and there's still plenty of time.
