warnersister is right on that part, those are very small babies, i figured you meant s/v length. they could have done well in the 5, but would have needed the 10 in a few months anyway. sorry about that. just remember to keep them misted well, and gvie em a few good hiding spots. my younger ones always love the larger leaf artificial plants. they also loved the base of a live spider plant i had in a tanke with them once.
