So I have had this Featherfin catfish for about a month now and it was doing great! Eating socializing ( my angels actually didn't bother it and they hate everything!) it had dark showy colors... But slowly it started to fade in color and hide more. No one bothers him he just seems to mozy along. He eats but not as eagerly as he once did. And I don't know it's a he I'm just guessing for now. My water is good. Nothing has really changed so I'm stumped. Anyone have any help???? Please!!!!
