White Flatworms

[swill]

I was going to get some Flatworm Exit on my next trip to the city (I live in a small town) but thought this might also work to keep them under control. I actually took some rocks out two days ago and did a freshwater dip which worked really well, the little buggers can't hang onto the rock once the freshwater hits them...but this is not going to get rid of them for good. I've read there is a slug that eats them but am not willing to take the chance with a slug in my tank and I do have a yellow wrasse that I was told eats them in there but he doesn't seem to be very hungry as they are expanding by the minute!!
