4 Line Wrasse: Flatworm Control?

[jawfishjunky]

I`ve recently noticed some small mustard yellow Nudibranchs in my tank. I think they are considered gold Flatworms. I know that 6 Line Wrasses are supposed to eat them. Do the 4 Line Wrasses also eat these flat worms?
thanks for your help.

I think most wrasses will eat them or other worms in your tank.
