I have a 29-gallon tank that is cycled, the stocking right now is only 3 platies and 3 guppies. The platys had red gills since I got them but I suspected it was because of the ammonia because I was cycling (Although I did dose Prime everyday to make the ammonia less harmful...) but right now the tank is cycled and I still see red gills, could it be gill flukes, or are they just stressed because they are all male and chase each other? I've also noticed white poop, it is not stringy, but it is white. One of the platys also had clamped fins when being chased, but it is only when he is being chased? Could there be a disease, or are they just stressed out?
