Yes, some will eat daily, but will stop when full(usually).

I have a couple that are on a 3 day schedule.
My 5 month old lesser is 500 grams(stuffed with 2 large weanlings).
She might eat every day, lol, but I have her eating at her rate and she just plugs along.
Her sibling sister is 300 grams and doing awesome, but doesn't quite have the same aggressive feeding response.

Your 5 day feeding schedule is very good, I'd stick with it if it's working well for him.
