hey everybody, I have an empty 180 (6X2X2) and have no idea what to put in it. I need some suggestions. I want some interesting fish, but I dont want to have the same fish as everybody else. Right now, the only fish I have is a 6" oxyeleotris marmorata (basically a water cow but grows larger). I don't want dats or arowanas, they just seem too common to me. I was thinking a ray or two, but that takes up almost no tank space. HELP PLEASE!! thanks
