I've had this guy for 6 months or so. Got him when he was just a wee lil fella. I had him in a 125 g with black substrate so his coloration was always very dark, which I liked. I moved him into a 29g with a female, and he lightened up a bit, and is showing a different color I've never seen before, kind of brownish yellowish. Kinda cool. Just thought I'd share.
