Hi, people! I was surfing the web at 1:30 am and I got bored. I uncovered Daron's tank and turned the lights on and noticed that his head was brown. During the day, his head is black/very dark maroon. I saw his head turned light brown another time, when it was night too; and another time, when he was freakin cold :/ poor Daron. The temperature was 26 degrees Celsius the last time when I noticed his brown head. I waited for several minutes and.. His head was still brown. Does this have anything to do with slowing the metabolism? Or stress, maybe? By the way, his body color is royal blue, his head is (usually) black and his fins are mostly red, with some blue on them, too.
