when i purchased mine about 8 months ago i recieved it with ich and i dont have a qt tank. the ich got soo bad that the blue tang could not see, all ovr eyes, fins, skin, and i would assume gills. so they told me the way to get rid of them was to...
1. buy a UV sterilizer
2. use garlic extreme
3. while the fish has the ich slowly raise temp to 82 then when there were no more on the tang they said to lower it slowly.
the higher temp makes the ich relese their host quicker, the garlic strengthens the fishes immune system, and the UV at proper water speed kills the ich.
since i have dont this i have not had one case of ich on any of my fish.
also with the garlic i add it right to the water instead of adding it to food, being that my tang was unable to eat being that he couldnt see this was my only option so ive been doing it this way since then. i only add garlic to the water whenevr i think something stresful happens like water change, or when ever you need to put your hands in the tank for any reason.
And now my tang is perfectly healthy about 6" and its eyesight did return, damage was not permanant, THANK GOD :cheer:
