I have had him for, I guess, four months. So its not dropsy or whatever. Its how he is shaped. He is a spear with tiny fins. I took these pictures at night/early morning when he was sleep drifting. His butt tends to bob upwards when he sleeps so thats why he is facing down a lot. I don't see any other pearlscales shaped as spherical as he is. Will he grow out of it? Is he just misshapen?
