My once active bubble nest building Mushu seems to not be doing better at all. First he stopped eating. Then he just started floating at the top or laying around on the bottom of the tank. About 4-5 days later I got him to eat 1 pellet. Now hes not eating again, he doesn't look bloated. However, he looks rather skinny. He is in a 1 gallon QT with nothing in it but a heater. Water changes every other day. He keeps his fins closed all the time now, also Mushu best picture is what I use as my avatar. The water temp is a stable 78*. I fear he is close to death. I am using boiled oak leaf to keep the water a bit darker. I really need some help I don't want Mushu to die
