Just yesterday I got a small betta who wasn't in very good condition but I wanted to give him a chance so I took him home. He's not very active, but he did survive the night so I hope that's a positive sign. Anyway, I'm not sure how much I should feed him because he's so much smaller than my other two betta. My other two get 10 pellets of Hikari Betta Bio-Gold a day but since the new betta is so much smaller I'm not sure if I should give him the same. Here are pictures of the small one and one of the bigger bettas, sorry they're a little blurry:
