I always cut frags off whatever they're mounted to anway, so taking a frag like this wouldn't be an issue.

I have never lost a fish to ich. I think ich is kind of like fleas on a dog if the fish has a strong immune system it can fight them off...marine velvet on the other hand is a nasty parasite :twised: .

ich-y frag
 

I think ich is a permanent resident of my tank already so I have no problem with frags coming from an ichy tank. Like others, I remove substrate from all frags and iodine dip them. I'm guessing that it's unlikely I would transfer ich in this way anyway.

Without a doubt.
