Ich in a reef.

[howdy20012002]

soaking the food in garlic only encourages them to eat the food
Honestly, I wouldn't worry too much about it myself.
Clowns are very tough and ich is more of a nuisance than a killer
the only time it becomes an issue is when it affects their breathing..ie gills
I personally doubt the ability of a cleaner shrimp to get rid of it.
even treating them in a QT is too late now as your tank now has ich, not just your fish...
To get rid of it out a tank, it has to be without fish for about a month.
If your fish are eating and healthy and your tank is in good shape the ich will be dealt with on its own
this, of course, is just my opinion and I am sure others won't and don't agree.
good luck in whatever way u decide
