Hey, could I get some general care info for these guys? My LFS has about 10 Of them at about 12'' and I really want to get one or two. They are really awesome. Was wondering if I could keep one or two in a 75G(42''x18''x24'') with a Crenicichla Cincta, 3xSilver Dollars, and a Vieja Argentea. Thanks Guys...
