I haven't ever picked up Kona or Bernie's food after a certain amount of time. Kona is a slow, picky eater, so I'd rather she eat when she is hungry. Bernie will often eat all of his food right after I put it down, but sometimes he'll take his time.
I think because they are so little it is better to let them eat on their terms - when they are hungry.
