this am i noticed my male auratus kind of resting on the gravel in the bottom of my tank, as i began to take a closer look i noticed that he is not moving one of his side fins and is unable to balance himself well he also appears to be semi-bloated. i just recently in the last few days had another fish appear bloated and doing the same thing he was also an auratus and died that day water parameters all test fine all other fish appear healthy so far any advice? tia
