I've been watching my guys change as they grow. The first photo is Bluey shortly after I got him. You can see his distinct white band. (When I picked him up, 2 weeks before I picked him up he was a butterfly pattern!) There's also a closeup of his fins a few days after he came home. His band is slowly fading and he's getting much darker. He's almost entirely blue at this point (as you can see in the small photo). I'll miss the band, but he's still pretty. He also builds incredibly large bubble nests.
