So my black moor always had a bronze/gold sheen to him, more noticable in the sunlight but when he was 2 years old, in the space of about two months he completely turned orange! And I mean Bright orange, not red or gold! So I guess he's just a telescopic eyed goldfish now and not a black moor i looked at my fish food and it says "enhance orange and red colours". so my question is, can you get pure bred black moors that will stay black? And did my food make him turn orange quicker? because I had one years ago that lived till it was old, grew massive and was always black.
