Master check above there is a sticky on ich Incysor is the one to answer this ........ I did a fresh water dip on my damsel ( when I had them) it worked and helped to rid it I also used garlic from walmart the gels puncture 1 gel soak in the food for 15 minutes , now it is proven that these are not as good as fresh garlic but that is all we had the ick was gone in about a week or at least from the fish , I also added another airstone to help with the breathing aspect for about 3 days (others opinions may differ on this) but here is my reciepe for ick
1 geltab (cut end off squeeze out)
, place on food if you use brine as a treat to get him to eat , if you use pelets soak in a little tank water .
now again this is the method I used along with fresh water dip
with the fresh water dip I used 1 minute incriments and distilled water at room temp , net the fish place him in a cup of tank water take him to the fresh water , set a timer for 1 minute in that minute you will be busy . Dip him in the fresh water it will look bad as he will go to his side rince the container containing salt water with hot tap water empty go to the tank get fresh salt water by now the timer should be beeping , place fish back in fresh salt water rinse fresh water dip cup in hot tap h20 refill fresh h20 dip fish repeate steps above 3 times for a toatal of a 3 minute fresh water dip . Return fish to tank let lights out for a while like 1- 2 hours or do right before bed ..........Now this is the method we use for ours some may disagree and say it is mean but we have had great succes with the fresh water dips and garlic combined method . Yes I am sure that it stresses the fish to be diped but it does help and I havent lost one by doing it , you may need to dip upwards of 1-2 weeks daily . The other method I have heard about is using a seprate dish /container placing matched salt water in and useing kick ich or copper treatment leave fish in for a couple of hours and return to tank . doing this daily till no more signs of ich are apparent . And never place copper in the display tank as inverts , and corals will react poorly to it .I have also read that ick is present in every tank but it is the fishes health and ability to fight it off ..
