I heard that there was like one fish that typically gets along with the D.P. fine. Does anyone know what fish that was? I know some people have good luck adding others with the D.P. but this fish typically has a great chance at not having problems with that. When I get my 55g, my 10g is going to be converted so a D.P. could live there, as the girlfriend wants one real bad... only problem is she wants more than just a D.P. in there.
