Question about flatworms and Flatworm Exit

[Myka]

How big is your tank? Adding a mandarin or a wrasse could help keep your tank flatworm free. Not all wrasses eat flatworms though, you would have to research. Don't buy a 6-line jerk though...they are the devil.

I wouldn't dose the tank as a prophylactic treatment, but I would have the Flatworm eXit to have on hand to dip new corals.
