So I meant to give an update about a week ago, thought it didn't seem there was happy progress to report. The tailspot was extremely sluggish, hiding, not really eating but its eyes were becoming clearer. Still very bulged, and then I noticed it didn't seem to be reacting at all to light being shone on it. Not even a twitch or "stress" colour change. This was making me think it has been blinded by the infection, but I just continued to keep the the triple threat in use..
As of today the eyes are clear, seem to be about the normal size, and best of all it seems to be seeing perfectly fine. Responding to light instantly, movement, and especially adding food. As of the last two days or so, the activity level has gone from hiding to very active movement and swimming around the QT tank. I'm planning on continuing another couple of rounds, maybe ~4 days, and then thinking of transferring him to a 100% sterile new QT tank for a while without meds to see if he truly is 100%.
Does this sound like a good plan? That would be about a month of medication use.., but I'd hate to be on the mend but then sabotage things.
