Yeah they still havn't touched it, I tried not feeding for a few days and got them close to it but still have showed no interest... I don't know why but none of my fish ever go on the left side of my tank... all 4 of them stay on the right... no idea why, is it possible they don't like the high flow from my return? I'm thinking about splitting my return into two over the edge returns to reduce the intensity and to even out the flow more.
