Every couple of weeks a fish or 2 die. All of a sudden they float upside down still breathing then usually die within 12hours. My tank is roughly 6 weeks old. I had the water tested a week ago and the water is fine. I have a 17 gallon tank. with 5 x cardinal Neons, 3 x molies 2 x Guppies, 1x clown loach and 1 x Another loach black with a red tail which is currently floating. So please help.
