as long as the bio gold+ has a good ammount of veggie matter in it, your foods look good. otherwise, add in a pellet or something high in spirulina.
i vary my feeding chedule up, and just toss in the tank whatever i grab at whatever time. in the wild they dont eat the same things at the same times everyday, so i try to not let them in my tank either. they may go a day, sometimes 2 or 3 days without getting a particular food/treat, and others they may get something 2 or 3x in one day.
