I found in my tank I lost a few fish to ich even with garlic but after I introduced cleaner shrimp the very next day the fish had improved and it took about 3 to 4 weeks with garlic and cleaner shrimp and it was gone.
After I introduced the shrimp I never lost any more fish.
Its amazing how fast the fish buddied up with the shrimp, within 5 minutes some of the fish were laying on their side next to the shrimp just waiting to be cleaned up, the shrimp were scared at first and tried to get away, but soon went to work doing what they do.
The success I had with the shrimp I believe is because the shrimp reach into the fishes mouth and gills and remove the ich as well as the outer body.
With out this cleaning the fish soffocate.
By the way where is the spell check on this system?
see ya.
