I've had this guy a week, he gets 4 or 5 hikari betta bio gold pellets most days (he came with this food so I haven't changed it), he's also had a few bloodworms once, plus a fast day each week. I'm not sure if he's a little skinny? I don't want to overfeed and I know how good bettas are at begging and looking hungry! He was even begging when I tried to take this picture...
