I feel like a good amount of time is 1-2 hours, anything under 15 minutes isn't considered very useful.
mine is obsessed with hunting snails, he's been doing it pretty much all day.
Your palembang hunts snails? If so thats impressive, since my old pair wouldn't even bat an eye for snails... As for the size, at 3" that is definitely one small PB... i wonder how fast they will grow at that size / age... coz my pair i kept for about 3 years and honestly didn't seem like they grew too much...
