My oranda, Juliet, is red and black with white on her belly and a bit on her her face. She has beautiful blueish hazel eyes and is very social and sifts through sand and follows my hand around the aquarium. She's a juvenile still and I got her because she had a heart shaped marking on her side. The heart was orange and it was surrounded by black. I loved it but assumed the black would fade away and she'd turn completely orange. However I just noticed that unlike yesterday, her heart is hardly there anymore but instead of it being because the black faded away, it is because the black is spreading. Because she's originally mostly black with some red I assume this is a normal color change? No ammonia and I did start feeding more protein and I have the ph at an exact 7. Is Juliet okay?
