i think my channel catfish might have parasites. for the last couple of weeks he has been breathing very hard and not eating at his normal rate. he also has long, white, stringy turds(which i read about and it means something bad but i forgot what it was). could he have parasites? what should i do. other tank mates are florida gar, red tail payara, poly ornate, LSN, Marble saiflin pleco, Jack dempsey and an orange spot sunfish. my channel catfish, gar, sunfish will be moved to my 1350 gallon pond soon but if the channel has parasites i don't know if i want to put him in the pond until i can cure him.
