Fluffy light poop

[crock]

Hi All. Please watch link.

This Juvenile Discus is showing an unusually thick and fluffy light colored poop (not white). I had given him Jungle Lab's anti-parasite food last 3 days which has pellets of same general tan color. Could that be just the tan pellet food coming through or some serious case of parasites? I gave him this food only as a precaution because the other Juvenile with him was showing signs of parasites (dark color, stringy white poop) so I quarantined him in treatment. This little guy seems otherwise fine, with no dark coloring, no scratching, no slime problems or odd behaviors. Water quality meets all of the safe parameters. Please help me find out with suggestions.

While this looks really bad as you say it could be as a result of the food you have fed. Finish the treatment as per the bottle then go back to normal feeding and see what happens. I would also vac this up asap when you see it.
