Rough Green Snake

[Sadie.bell]

Hi everyone! I recently found an adult rough green snake and what looks like a newly hatched black racer. i was wondering if it would be ok if i put them in the same aquarium? they're both so small that i figured they'd have plenty of space. and on more thing, exactly what do i feed the baby black racer? it's so tiny i thought maybe cutting a pinkie mouse in half lengthwise might make it a tad bit smaller so he could chomp down?
