hello all, I really need a solution to this, I have a cold-water platy who is a male about 2 years old, for the past two days he has been really struggling to get up off of the ground of the tank where the stones lay, he has way larger fins than usual and when I transfered him to his own tank, now he seems to be struggling to keep himself upright, he's definitely still breathing and he's still slowly dragging across the floor of the tank every once in a while, please let me know what's wrong someone
