feeding crix more than one crested in tank

[ColleenT]

i was feeding some crickets last night, and i watched them, b/c i like to watch them hunt. well, two times, they accidentally went for the same cricket, and ended up biting each other. i was there to separate them, but i wonder if i should put them into separate enclosures to feed them crickets. Do any of you have two or more in an enclosure, and have you had this problem? mine are still too young to sex, and are about the same size. the oe is only slightly larger than the other. and they do not get aggressive towards each other.
