[fishyfinder]

well since i have added a new male to my male guppy tank everything has gone wrong. i added this male and my fish acted normal for the first few days so i thought everything was fine. When i went to feed them i found a few of them with their color faded and then the next morning two were dead. they turned almost white and looked beat up but werent beat up so i dont know what it is. Now im almost out of it, i saved three from the illness whatever it is and now they eat fine and will peck on the ground but swim endlessly on the surface against the filter current.
please help me. I have no clue what it could be
