I had an albino tiger Oscar few years ago that I got from lfs as a baby and had black markings like this and he was super healthy and grew to be like 10inches and still kept the black pigment

yep they are perfectly healthy, I was reading on Wikipedia I think that albino Oscars with he black markings are in fact not true albinos but are called a "Lutino" Oscar mine is a baby now about 2.5 inches and thriving. The Blood red parrot fish (which I have one of) will turn black if it is stressed or the water quality is bad. I had that problem and tested the water to find the ammonia levels were off and put an ammonia filter bag in my second filter system as soo as I did that with in 5 days the blood red was bright orange and the black is now almost completely gone. Needless to say I use he blood red as a water quality gauge and if it goes black again I know something is wrong
see nothing wrong with him, its a lutino, not a albino, they get graying on the fins, I would rather have a lutino than an albino, albino,s tend to come with issues, like seeing.
