Update...I first noticed the black in him when I changed the backround to black, so I thought that could have been what was making him do it. I took half of the natural substrate i have in there out. It is quite bright and I think it was stressing him out. Mixed half all black substrate that came with my 100 (the guy had enough for like 2 100's) And he loves it . I'm deff not saying his color change has ANYTHING to do with the changes I made. He just likes the "calico" kind of mix I made. It looks so good I may do it with a bigger tank in the future.......Oh yeah the update, he is turning white now NO black at all pretty cool. Its like a gamble he could be any color when he groes up. I'll post some pics of the tank and him.
