My black asian scorplings left their mom last night and now i have abt 15 or so or them in a 2 feet tank , they are varocious eater eating 4 adult crickets last night and now they are hiding all over the place, how do i continue feeding them, should i kill the prey abd leave it lying around or should i place it near them? which is sort of hard as they dont travel in groups and some are in the smallest stone crevices that i am surprise how they got in .
