Fish scratching more after garlic?

[bridge man]

I have been feeding some garlic soaked food to help combat a minor ich problem. I noticed that about five or ten minutes after I feed my fish, they begin to scratch more on the rockwork. The clowns and kole tang are doing this even though they show no signs of ich, as only my bicolor blenny shows some signs of the disease. Could the garlic be acting that fast to cause the ich to be irritated and thus irritating the fish? Would the ich detaching from the fish cause them to scratch?
Thanks

Yes, I suppose that's possible.

Dang that was fast. I hardly had any time to start working. I figured that was the case with the scratching, because they wouldn't scratch at all for the few hours I am home before I feed them. Then, after feeding, they begin to scratch. It is all quite perplexing to me.

Yes, but not definative. Keep us posted on the progress of your fish.

Well, the bicolor blenny isn't looking too good. It's a good possibility that he'll pass this weekend. I am not going to be home this weekend, so hopefully the hermits, emeralds, and peppermints will take care of the body. I do have someone to feed the clowns and tang garlic soaked food while I'm gone, and with any luck, they will remain disease free.

Well, you're best bet for avoiding such losses and hassles is to QT fish before they go in to your tank. Its better than jepordizing every fish in your tank.

Thats just the thing that makes this whole ordeal more of a mystery. I did QT all my fish for three weeks prior to placing them in the main tank (Not all at once, but rather over four to five months). I think the thing that set off the attack was that the bicolor made it into my overflow box, thus causing him to be stressed to the point of allowing ich to take hold.
