yeah i have a powder blue gourami who has been staying at the top of the tank for like the past month or so. I'm really not sure why. I just did a water change this Sunday, thinking that there was something wrong in the water, but he still stays up there. Now i know that they are top dwelling fish, but he stays like a few millimeters below the surface and he rarely strays to the bottom. in fact he rarely even moves from his little spot behind the output of the filter. He eats normally, but then just goes back and doesnt move. please help!
