My wrasse is eating Ich!

[reefwithareefer]

Ok, I am not sure if this means anything or not. It may be known already, but I recently bought a Lubbocks Fairy Wrasse from my FS along with a Hippo Tang and some others.
About a week later, I noticed the Hippo had Ich. Not going to discuss where the Ich may have come from, because what interests me is that the Lubbock started to chase the tang. At first I thought it was being aggressive towards the Hippo. It seemed to be nipping at the Tang etc. Then after watching it for an hour or so, I noticed the tang not swimming away. Then the tang started to let it nibble at him and that is when I saw that it was actually biting the Ich. It was plain to see.

Within a day or two, the Tang had no more Ich. I am not saying the Lubbocks ate/killed it. The Ich could just be cycling or maybe the Lubbocks removed it from the tang but did not actully kill it...

All I know is that the Tang and the Lubbock do not have any visible Ich at this point. It has been approx 3 weeks since I first noticed the Lubbock doing this.

Has anyone seen this happen? Is it possible this fish will destroy Ich or at least take it off another fish?
