Update...a lot of controversy here.
The Ich appears to me mostly gone with the garlic and water changes having done the trick. I am thinking of upgrading my skimmer now as the added feedings are causing a diatom bloom. (or perhaps I just need a reason to play with the gear!
)
Until a few weeks ago I can say with certainty that there was no Ich in the tank. Every fish with the exception of the last addition has been QT'd for at least 4 weeks to break the cycle.
I got impatitent with the blenny I recently added and he went in the main tank after only two weeks. Now I know better. I've been at this hobby for about a year and a half now and this is my first ich case.
None of the other fish are showing any signs.
Thanks for help Em, Carp, Riff, AJ, etc..
