ok guys. I have had my tank up and running for about 2 years with no ick. I turned on the lights this morning and saw that my regal has 2 spots on him that are under the skin. I assume its ick.
My question is will it hurt to treat ALL of the fish in a QT
even though they dont show signs? Secondly, I have 4 small fish (1 tang about 2 inches long, 1 perc, 1 damsel, 1 velvet dottieback.), will this be to much for a 20 gallon QT
Lastly, I spoke to a guy at a LFS
that is very large in this area and his theory is ick is always in a tank and you can never get rid of it. Its either in the fish or water. He said he has had a tank for 2 years and has added nothing in over a year and found ick on his fish the other morning for no reason. Plus I was reading the posts and saw where Revtree has batteled this for a long time. Im beginning to wonder if this theory isnt right?
I dont want to QT
my fish unless I have to. Should I wait to see if the tang developes any more spots before putting him in QT
along with the others?
