I have a little Gold Ram in an established QT, she has been there about 10 days. Ammonia 0, Nitrite 0, Nitrate 5, pH 6.6, Temp 79F She has been constantly loosing weight (her stomach is now inverted), hanging at the surface and has bright red gills which are always open and I can see inside under her Gill cover to her gills at all times. She coloured up then lost the colour after around 3 days (although she still has some). I have never seen her open her mouth and have just closely watched her try to eat for the first time. She swims over to the food so fast (then I have half watched her, half carried on feeding the others as she eagerly went over) nudges the food but never opens her mouth at all. It is open about 1mm. I have watched her for a couple of hours now and her mouth appears as though it cannot open or close at all. It just doesn't move. Please help me to help her!
