Mandarin vs. flatworms

[Frenchie2]

I got flatworms and got a yellow wrasse and psychedlic mandarin. My yellow wrasse did a fabulous job and I suspected the mandarin had something to do with it too as he is getting fatter and fatter (I don't even feed it - he feeds on copepods and probably flatworms). My yellow wrasse jumped out the boat recently (through egg crate cover, can you believe it), and I found the population of flatworms increasing quite a lot. So, I believe the mandarin helps a bit but definitely the yellow wrasse did an outstanding job!
