yeah, it was crazy he had one large spot that was huge i debated whether or not it was ich for a few days, but added a little bit of garlic to help him heal. waited a few days and did like a 70% water change to remove the garlic as it stinks after a bit, and that night when we got home he was covered in spots, like well over a hundred would be my guess. I too thought about the gill issue, too many of them on the gills and when the dip makes them irratans "explode" it damages their gills. I had also emptied the tank and pulled everything out so it wouldnt come back after the dip.
I would have taken much more serious action earlier on if I had thought it really was ich.
@sniperhawk, its important to match the ph of the dip water to the tank water, or you risk throwing your fish into shock. I used baking soda to raise it, vinegar will lower it.
@cccapt, i did not konw the gills were the first point of penetration... As soon as I get a ph meter fw
dip will become part of my qt process.
