hi all woke up this morning to find one of my Pictucs catfish not very well. The water perimeters in the tank are all perfect (before anyone asks) the fish is breathing very rapidly and doesn't really have any control over his swimming. He was fine the other day, it seems to of happened over night, and he looks like he could die any moment. Does anyone have any ideas as i don't want to lose him. I have quarantined him.:cry:
