Wow guys. Thanks so much. All that makes total sense and really helped me out a lot. They are in their own cages now and seem to be calm and starting to adapt to new homes.
I freaked out when I thought about eating, stress, and things like that, so I ran to Petco to get a new aquarium and lid, and on the way back home I realized that I had an old heavy glass aquarium (a 30g tall for fish) that I had a while ago and then bought a wider one about a year ago. So, a long story short, I had everything I needed for a second habitat right here!! Thanks everyone for your words!!
