I have had my female JD for just under a year now. She is 6.5" her growth spurt has passed but she is still slowly growing. I have kept Jacks in the past and they have always been black with metallic blue and purple scales. The one that I have currently has some of the blue but she is mostly an olive green color and purple.
The only time she gets really dark and turns any shade of black is when she gets stressed out. Mostly when I get the gravel washer out. I can do water changes and move my hand around in her tank and it never bothers her, but whenever the gravel washer comes out she turns really dark and runs off and hides in one of her caves. She has a great personality and is by far my favorite fish I have ever kept.
Anyways I was wondering if this color pattern is common, I had never seen it until I got her. I posted pics down below.
