Six line wrasse eats ich off other fish????

[fishoholic]

I was reading up on six line wrasses and I read a few posts (from other sites) on how their six line wrasse ate the ich off of their other fish. Has anyone ever heard of this or seen it done?

I'm asking because my lavender tang has ich. The ich doesn't spread to the other fish and other then the white spots on her my lavender tang looks and acts perfectly healthy. She's nice and fat (eats lots) and doesn't try to scratch or itch herself on any of the rocks or sand bed. It's really annoying to see white spots all over her, if a six line could help that would be fantastic!

I have thought about QT but it's to hard to catch her in our 230g and if we take her out we won't be able to put her back in without the other tangs trying to kill her.

If anyone knows if this is possible please let me know
