I got my first FH and am wondering what kind it may be. The first picture is when I first got it home. it has the 3 black marks on its right side. The second picture is two weeks later. His horn has grown a lot and he only has the 2 marks on his left side. The ugly bright gravel I had in the bottom was originally for a tank for my girlfriend who was getting her "cute fish" then I stumbled upon this FH and had to put him in here since he was unable to co-habitate with my oscar. So the gravel highlights his stomach, it isn't usually pink like that and he is a lot more blue that the picture portrays. Any help identifying would be a help. Thanks.
