Okay, I've had my Betta for exactly 9 days. His name is Prince William because I was watching the Olympics when I was thinking of names for him.

He's a Half-moon Betta and his fins were like that when I got him. So I'm taking care of that with Bettafix.
Anyway, I've never noticed it before until I started reading articles about Velvet disease. So I'm not sure if he's always had a gold-ish hue and I'm just being paranoid, or if he really is sick. I've answered the form and will attach photos next.

Food
What type of food do you feed your betta fish?
I alternate with pellets, dried bloodworms, and dried mysis. He doesn't like Daphnia.
How often do you feed your betta fish?
2 pellets in the morning and 1 at night. or 1 bloodworm cut in half in the morning and another one at night. (I do this same process with the Mysis. I have to cut it because it's too big for his mouth.)
I didn't feed him today because I read that I have to skip a day to help him clean out his system. So I'm thinking I'm not going to feed him on Tuesdays.
