I upgraded my planted 37 to a 55 today. The fish went into a 15 gallon tub with some of my plants, the bio-max from my filter, and an airstone under the bio-max. The 4 gouramis seem to be doing fine aside from some shyness. My angel, however, looks sick. He eats and his fins aren't clamped, but it looks like he has some kind of film that's peeling from him. Does anyone recognize this? He was the picture of health before the move.
