Gary--
I noticed a small group of flatworms in my tank at home and want to crontrol them before they reach epidemic levels. I dont want to use FW exit until its a last resort because Im not sure how it would affect my nudis or other simple inverts. Is this the fish you use for flatworm control? If so I wonder how it will cohabitate with an 8 line wrasse (in a 400 gal).
