does anyone have any tips for pac-man frogs??

i currently don't own one but i want one so bad, im looking at one right now but i have absolutely no clue on how to care for it

i have a few main questions 1)iv looked on a few websites but nothing is too in depth on how to care, it only says when to feed it nothing about what and other websites say other dates so if anyone can confirm what to feed it and how often to feed it that would be awesome. 2) what's the ideal size tank?? 3) do i need a light source if so what kind 4) how to set up their tank if you have a picture describing what is what that would be amazing 5) are they handleable?? 6) do you need to have multiply pacman frogs in one terrarium or are they solitary??
