I give mine 1 or 2 pellets a day, and frozen brine shrimp every day, except 1 or 2 (diet day!) And then around 5 or 6 live brine shrip weekly. Once a week, I will give them some veggie flakes, and only once, I have given them cucumber, which they ate, but didn't enjoy...
I feed mine 3 pellets, 3 times a day unless 1 escapes and sometimes 4 go in!
So when I get up, then again at 3pm then again before I go to bed
And once a week, frozen bloodworm or daphnia or brine shrimp but no pellets that day and a day of starvation too
