I have a little platinum plakat male and last night he had finally settled into his new home and was flaring and munchin on bloodworms happily. Then this morning (I have to get up super early on thursday mornings for class) when I turned on his light, he had lost ALL of his color! I was so worried! He looked like a muddy brown when he's usually dark silver-purple. And he didn't move. I left him alone for a couple of min, then when I came back he was still in the same spot. I was going to freak out because I don't know what could be wrong. Then, he yawned! And immediately started swimming around looking for food and his color came back almost instantaniously! (Thank God). I guess I just woke him up too early!!! Now he's flaring at the calendar like a happy boy!
