I've had my Blood Parrot Russell for almost two years now. He lives alone, and I moved him to a new tank in October and I believe he stressed and shed his slime coat. I fixed him all up so he's not shedding anymore, and hasn't been for a while, but he's stayed white. He used to turn white if I left him for a few days, but then turn orange about the day after I got back. He hasn't returned to his normal color, though. He's a Blood Parrot, not a dyed variety, so I don't know if this is a normal part of him growing up, if there's something I can give him to make him turn back orange (he looks so sickly, but his behavior is very healthy!), or if there is an underlying issue. All water parameters are fine, so what could be the issue?
